T
his issue of Modern Aquarium has several elements that are familiar to our readers, and a few elements that are a little bit unusual. For instance, we have not one, but three CARES-related articles, led off by Tommy Chang’s “Who CARES?”. Of the remaining two, “Paratilapia sp. ‘fony’ is written by a Greater City member (me), but reprinted from another publication, Buntbarsche Bulletin, and the third, “Melanotaenia of New Guinea” is a new article written for us by Derek Tustin, the author of an article we re-printed back in May from the Durham Regional Aquarium Society’s Tank Talk. Another unexpected voice this issue is former Greater City member Charlie Kuhne. See Charlie's “How To Get Out of the Fish Biz? Move!” on page 16. Charlie also has an ad in Member Classifieds for his house out in New Mexico. Dan Puleo’s “The LFS Report” this month features World Class Aquarium, a shop that has been a regular advertiser in Modern Aquarium for many years. Steve Sica gives us another wonderful photo essay of one of his and Donna’s traveling and diving adventures in “Shark Diving at the North Carolina Aquarium.” Appropriately, Sue Priest’s Wet Leaves column this month features Steve’s contributions to Modern Aquarium. Sue also once again contributes the always-popular “Pictures From Our Last Month’s Meeting.” Meanwhile Al Priest contributes another of his astute and informative articles, this time on Betta ocellata, the “eyespot betta.” The Undergravel Reporter tells us about noisy, satellite-spawning midshipmen (not from Annapolis), and the issue closes with our monthly Fin Fun puzzle. 2
Remember, we need articles. We always need articles! Modern Aquarium is produced by and for the members of Greater City Aquarium Society. Our members are our authors, and with ten issues per year, we always, always need more articles. I know several of you are keeping and/or breeding fish that I would like to know more about, and I’m certain other members would be interested as well. Share your experience with us. Write about it! If you’re a little unsure about the state of your writing technique, don’t worry – that’s why there are editors. If you have an article, photo, or drawing that you’d like to submit for inclusion in Modern Aquarium, it’s easy to do! You may email it to gcas@earthlink.net, fax it to me at (877) 299-0522, or just hand it to me at a meeting. However you get it to me, I’ll be delighted to receive it!

President’s Message by Dan Radebaugh
A
little over a year and has passed since Hurricane Sandy's visit, and since the meeting that didn't happen. But now it’s time to turn our thoughts forward. About a month from now, on December 4th, we will be gathering for our annual Holiday Awards Banquet. Last year we held our banquet for the first time at the Flagship Diner on Queens Boulevard. Last year Flagship charged us $22.50 per person. The club picked up $2.50 of that, and so members paid $20 each. This year the price has gone up by a couple of dollars each, but the club will make up the difference, and members will once again pay only $20 each. Think about that—a year’s membership in Greater City is $20, which includes monthly speakers, refreshments, auctions, raffles and door prizes, not to mention the camaraderie of hanging out with people who share your interest in fish. On top of all that,
another $20 gets you a great meal and dessert, and yet more festivities! Is this a deal, or what? I pay that much for a container of freeze-dried krill! And I don’t even eat them! Last month I asked for some volunteers to help the club in various ways, and I was pleased to get a few positive responses. I’ll be speaking with our new volunteers to see how they can both help us out and do something that interests them. More news will be forthcoming soon! On another matter, I recently received the letter below from Christine Policastro of the North Jersey Aquarium Society, which I thought our members should see. See you at the banquet!
Dan
October 12, 2013 Dear Greater City Aquarium Members, On behalf of the Board, Officers and membership of the North Jersey Aquarium Society, I would like to thank you for your support of our 60th anniversary event, by sponsoring two classes in our All-species Tropical Fish Show. No hobbyist club could exist without the support of their members, local pet shops, vendors, manufacturers, and sister societies. The reality is we have been a viable club for sixty years because of the support we have had for all of those years. NJAS is only one of a couple of aquarium societies in the northeast that have an annual show, so your support of the event is important not only to NJAS, but to the tropical fish hobby as well. NJAS is renowned for their amazing ability to consistently organize a fun and informative event, and this year will no doubt prove to be especially extraordinary. Your sponsorship of show classes this year will help to defray the cost of our show, and provide hobbyists a great opportunity to view a large number of show-quality fish. It may even generate new interest in the hobby with the number attendees expected who are not familiar with North Jersey or the organized hobby. We are aware of the tough economic times most of us are still facing, and yet you offered your support. In closing, I would like to thank you once again for your continued support of our organization. You have supported our annual show throughout the years, and we greatly appreciate that! Sincerely, Christine Policastro NJAS Show Class Sponsorship Chairperson

Who CARES? by Tommy Chang
ou all may recall a blurb from me about GCAS CARES about a year ago—how the CARES program here at the GCAS had a slow reboot at the beginning of 2012, and how I intended to contribute to the program by managing it. Unfortunately, I must humbly accept responsibility for the fizzle in the progress of that revival to date. I would also like to apologize to anyone with CARES fish who were due awards for their efforts at conservation, such as Jules Birnbaum and Al Priest. I quote King Hal, Henry V in the play of the same title: “Once more onto the breach!” At the beginning of 2013 I broke my right foot; I then had weight and hip flexor problems which required physical therapy. Finally, I had cataract surgery. It was a grueling year of doctor’s appointments. But I am happily back! They say the third time’s the charm, but I hope to nail it the second time around—or is it actually the third time around—this being the third year? Anyway, thanks to all, and I urge you to get involved in this worthy project. There are a few ways that you can participate. First, and most important, you can devote some tank space—you decide how much—to keeping, breeding, and distributing to the hobby an at-risk species. You can help me run the CARES program. What that might involve is unclear to me right now, but if the program prospers, we will need to keep records, perhaps institute an awards program, and communicating with other clubs so that we and they are truly involved in this program that may be the last hope for survival of so many at-risk species. At the very least we should have at least one person acting as backup so that one of us is always present at our regular club meetings. If you would like to help out, please let me know or tell Dan, who will pass the info on to me. Thank you, and Happy Fishkeeping!

The LFS Report by Dan Puleo
LFS in the spotlight: World Class Aquarium 2015 Flatbush Ave, Brooklyn, 11234 www.worldclassaquarium.com
T
his month the LFS Spotlight falls on a store that is new to me, but an old favorite for some of our members: World Class Aquarium. I had been to the shop only once before, but was happy to return to do this article. World Class has been a part of the Brooklyn aquarium scene since 1986, and has flourished in that time to be considered among the best. Anyone familiar with the Brooklyn shops knows that that’s saying a lot. If you’ve never spent a day fish-shop-hopping in Brooklyn, you’re missing out. While talking with the owners and employees, and looking at the tanks, a common theme in the best shops once again becomes apparent: beautiful, healthy fish and serious customer service. I spent quite some time talking with Dwayne, who maintains all the tanks and cares for all the fish with a passion that is incredible. Once he got rolling about “his” fish, and how he works with “his” customers, I realized that here was someone with a love of fishkeeping that rivals or exceeds that of any member of our society. He grew up in Jamaica (NOT Queens!), and some of his earliest memories are of diving to look at the fish on the reef when he was three. While growing up he earned a living capturing fish for the aquarium trade, and he came to New York when he was 21. Not long after his arrival he started working at World Class and has never looked back. He is serious about how his customers take care of their fish—he won’t sell you any fish until he knows what size tank they’re going into, and what other fish are in that tank. If he thinks you shouldn’t be adding those fish he won’t sell them to you, and if you return with a sick fish he Modern Aquarium - Greater City A.S (NY)
insists on getting a water sample, keeps the fish, and won’t return it until “we get your water dead on right.” He also has a passion for breeding cichlids, and loves to try different crosses to see what will come of it. It seems like his bosses take very good care of him and give him the room to do his breeding experiments. He had a white Midas cichlid and a flowerhorn in a cube tank preparing a spawning site as we spoke. “Watch this.” he said, and reached into the tank. The Midas immediately came up to be petted! “I love my fish and they love me.” Once his hand was out, it was right back to prespawning. Some of his crosses have come out quite beautifully, and have sold for as much as $300! This shop’s love of big fish is obvious when you see the 280 gallon tank. It contains a 3-foot silver arowana, red devils, buttikofferi, Oscars, a gorgeous gold tilapia, plecos, and a lukanini that’s obviously one of Dwayne’s favorites. All he has to do is look at it, and it acts like my dog when I come home from work. While I was there, some of the other fish that stood out to me were the silver distichodus ($5), beautiful monos ($10), and the dollar sized red-eyed platinum pearlscale angels ($10). There were large rummynose tetras ($2.50) that were properly colored up, and Odessa and black ruby barbs ($7) that make you realize what these fish should look like. In the African tanks the yellow labs ($9) absolutely glowed, and I was treated to a species I had never seen or heard of before—Aristochromis christyii ($20). They also had impressive lyre-tailed peacocks & kenyii ($7)

and blue dolphins ($8). All fish are “buy 3, get the 4th free.” On the salty side, all the fish and inverts looked incredible. I was especially impressed by the yellow carpet anemones. It turns out that Alan, one of the owners, is a marine biologist, so you know you will be getting the best advice when you come in with a question for that side of the aisle. As to other aspects of this shop that make it special, one is that they make all kinds of custom tanks. This is the work of the other partner, Robert. He had rimless flat-back hex tanks, and lots of oddball sizes ready to go in “the tank room,” and his talent and creativity show in many of the stock tanks. I had never seen a store with the top shelf tanks shaped so that the front glass is tilted down toward you at about a 30 degree angle, but it certainly made for easy viewing.
12
He also makes some impressive custom paludarium tanks. The other side of the coin at World Class is their birds. You won’t just find the typical parakeets, finches, and cockatiels. Here you can find the big boys: conures, parrots, cockatoos, and more— both hand-fed babies and adults. Of course you will also find a knowledgeable and dedicated staff to make sure you know what you’re doing when you consider making a purchase—just like on the aquarium side. So take some time to go visit World Class Aquarium. It’s definitely worth the trip!

are paternal mouthbrooders (meaning that the male holds the fertilized eggs until they hatch). Based on my experiences with many other mouthbrooding Betta species, once the fry are released and are free-swimming, the parents will take no more notice of them, either by providing care or predating them.

Betta ocellata is a paternal mouthbrooder and the male incubates the eggs from 12 to 17 days. (Incubatio n time can vary with water temperature.) Females normally initiate spawning. 5 There are varying opinions on the difficulty of having these fish breed in the home aquarium. One source claims: “Eyespot mouthbrooders are very difficult to breed in the
November N ov ember2013 2013
Modern Aquarium - Greater City A.S M odern A quarium - G reater C ity A .S. (N Y )(NY)
aquarium. In the wild they will breed in waters with very low pH. The male will mouth brood the young; at this stage it is best to remove the female to prevent aggression. When the fry are released they can be fed on rotifers or newly hatched brine shrimp.” 4 On the other hand, I obtained my fish from a member of our aquarium society who apparently had no problem in breeding them. My specimens have not yet spawned, so I’ll withhold judgment on the degree of difficulty of breeding in the home aquarium. I can at least attest to the fact that they are very easy to maintain, and are not demanding with respect to precise water parameters or food (so far, I haven’t found a fish food that they won’t eat!), but they do prefer cooler water (in the mid 70s). There are two schools of thought regarding what should be done with the female while the male is holding eggs. Some breeders remove the female, others do not. For Betta bubblenesters, the female should always be removed when the male starts tending his nest, as he will attack any fish, including his mate, that approaches that nest. However, in the case of Betta mouthbrooders, I have never seen a brooding male attack his mate. On the contrary, I’ve seen several instances where the female positioned herself to guard a brooding male. The best argument for removing the female is that once the male has released free-swimming fry, she will attempt to mate with him almost immediately thereafter. Since his mouth was filled with fertilized
eggs, the male has not eaten for over two weeks by the time the fry are released; and he needs time to eat and regain his strength. My recommendation is IF the female can be removed quickly and quietly (so as not to alarm the male who, if alarmed might eat the eggs), do it. Otherwise, wait until the fry are free swimming and remove her then. As with all Betta species, Betta ocellata are prone to sudden and sometimes quite dramatic and long jumps. A tight-fitting cover should always be in place. I find that caves and bottom-level hiding places (plants and driftwood especially) help reduce some of the tendency to jump out (when startled, the fish will usually head for a place previously determined to be safe). Caves also provide a place for the male to stay when brooding the eggs in his buccal pouch, and driftwood helps to lower the water’s pH. (While Betta ocellata are tolerant of a wide range of water parameters, a lower pH appears to be most conducive for spawning.) This is not a very colorful fish, but it is interesting and not at all shy. It will accept almost any food you give it and beg for more. It tolerates a wide range of water parameters (but regular water changes are still required). While not common in local shops, it is fairly well established in the hobby and available through local aquarium societies (which is how I got mine) or from the Internet.

How To Get Out of the Fish Biz?
MOVE! by Charlie Kuhne
A
ngels, angels, angels... Black, marbles, golds, lace tails, lyretails, and super lace. I had been a member of GCAS for over 20 years through 1993. In the final years I specialized in angels, bringing bags of young fish to every meeting for auction. That year we discovered our dream retirement home in a small town called Truth Or Consequences, New Mexico. We were to move on January 31, 1994, and needed to dispose of everything in a two to three month window. Fortunately, GCAS member Richie Gambina bought my entire collection of tanks and fish. Richie had been disappointed by past claims of “guaranteed breeder angels” that did nothing, but within a week he was delighted to have his first spawn. Today those who know him can tell you he has a house full of angels. Back in T Or C a few years later, I picked up a 20 gallon high at a yard sale (whatta mistaka to maka). So on my next trip to New York Rich loaded me up with angels and twin corys. In those days you could travel by air with shopping bags full of fish!
16
So began (again) the proliferation of tanks and fish throughout the house, until my wife Shirl got peeved about angelfish staring at her while she bathed. She swears that they gathered in the nearest corner of the tank, pursed their lips, and whistled. I managed to escape the situation with my life and at the same time expand my hobby by creating a 10-tank fishroom out of the carport—and a depletion of almost twenty grand from our bank book. Now it’s almost 20 years later, and I’ve managed to sell off my breeders and adult fish, leaving me with five empty tanks, but a slew of fancy guppies, assorted swordtails, and a handful of immature cory catfish. Oh yes; I forgot to mention that a year after the carport conversion we built an indoor pond to house our tropicals as well. I’m ready to get out of the fish biz again—does anyone want to buy a house? Help!!!

The obvious choice was a lionfish. But what about the Fish Bytes logo, or maybe one of Steve collecting a few of his writing awards? For some reason I was particularly drawn to the December 2011 cover photo of a barracuda, but in the back of my mind I kept returning to a photo of Donna and Steve which was taken at the July 2013 GCAS meeting (printed in the August issue) showing yet another side of this dynamic duo, their patriotism.
In 2011 Steve wrote an article called “Aquaria as Art.” In it he describes the “renovation” of a small aquarium. In my opinion, his description of a “gray and white striated rock with a small pointed peak - sort of a three inch miniature Matterhorn,” demonstrated a particularly artistic flare for writing as well as decorating. He goes on to say that “Modern Aquarium is itself a higher form of art, thanks to all the people who are responsible for its being. It is my singular honor to occasionally contribute in a small way.” Amid all of his talent is a streak of humility! Thank you, Steve, on behalf of all of our readers, for filling the pages of Modern Aquarium to overflowing with your insights, your photos, and even a few smiles along the way!

Melanotaenia of New Guinea A Crisis on the Horizon? Or One Already Here? Part I by Derek P.S. Tustin
I
n this hobby, we all have one or two, or sometimes even three passions that we follow before everything else. For some it is cichlids, for others livebearers, some anabantids, and still others cherish catfish. Me, I have two passions – aquatic plants and Sahul rainbowfish. When I first got into this hobby in a serious fashion, Sahul rainbowfish were the ones that first caught my attention, and are the ones that have held it ever since. I’ve dabbled with keeping other types of fish, but time and time again I return to rainbowfish. But even further, I have found that of the 10 genera that are considered Sahul rainbowfish, Melanotaenia are the ones that capture my attention the most. I’m hoping that most of you are somewhat familiar with Sahul rainbowfish, but for those of you who aren’t, let me tell you a bit about them. First off, I should point out that I am only addressing the Sahul rainbowfish, and am not looking at either the Celebes rainbowfish (Marosatherina ladigesi), or the Madagascar rainbowfish (the Bedotiidae family encompassing the Bedotia and Rheocles genera). Sahul rainbowfish consist of two families of closely related freshwater fish, Melanotaeniidae and Pseudomugilidae, that originate from and are restricted to Australia, New Guinea, and several small islands off the coast of New Guinea. While there is some controversy over Pseudomugilidae being a separate family or a subfamily of Melanotaeniidae, they are all commonly referred to as rainbowfish. The two families, with their associated genera, are: Melanotaeniidae Cairnsichthys (1 species) Chilatherina (11 species) Glossolepis (9 species) Iriatherina (1 species) Melanotaenia (60 species) Pelangia (1 species) Rhadinocentrus (1 species) Pseudomugilidae Kiunga (2 species) Pseudomugil (15 species) Scaturiginichthys (1 species) Modern Aquarium - Greater City A.S (NY)
It must be emphasized that the number of species listed for each of the genera is not static; new species are being discovered all the time. For instance, of the 60 known species of Melanotaenia, 22 were described between 1843 and 1979, 16 described between 1980 and 1989, 10 between 1990 and 1999, and 12 from 2000 to the present day. (In fact, the most recently described Sahul rainbowfish, Melanotaenia sneideri, was only first formally collected in March 2013 and first described in July 2013.) In other words, of the 60 Melanotaenia species currently described, 38 of them, or approximately 63% of the entire genus, were described in the last 33 years. When you consider that the earliest description of a Melanotaenia species occurred in 1843 (170 years ago), you can see that the past three decades has seen a virtual explosion of knowledge about rainbowfish. Overall, they are relatively small and very colorful, with all being native to freshwater habitats, although some can tolerate brackish water. They can be found in a variety of habitats throughout Australia and New Guinea, including rivers, lakes, and swamps. They are usually less than 5” (12.5 cm) in length, although some species are reported to grow up to 8” (20 cm). As mentioned, the first Sahul rainbowfish was described in 1843. Since then countless ichthyologists have tramped through Australia and New Guinea, poking, diving, and wading into further countless bodies of water and finding new and wonderful forms of these fish. In the past 30 years the two most prolific discoverers and collectors have undoubtedly been Dr. Gerald Allen and Heiko Bleher. But… Why Are They From Two Places? I’d bet dimes to dollars that most of you have never heard of Sahul. So to confuse you, I’ll tell you that rainbowfish are from Sahul. During the last ice age, about 18,000 years ago, the sea levels were substantially lower around the world. As a result of the lower sea levels Australia, New Guinea, and Tasmania were actually one land mass. (In fact, from about 100,000 years ago to 5,000 years ago, some part of Australia was always connected to some part of
November 2013

New Guinea.) The attached map shows the current landmasses of Australia, New Guinea, and Tasmania outlined in red within what was the Sahul continent of 18,000 years ago.
But why can’t people just (easily) wander through New Guinea and discover stuff? Well, the population of New Guinea is not homogeneous, but rather heterogeneous. (Didn’t know you were going to get a language lesson, did you? Homogeneous = composed of similar or identical parts, uniform in nature. Heterogeneous = differing in kind, having unlike qualities or characteristics.) The inhabitants of New Guinea have several thousand different communities or tribes, most with only a few hundred members. Each group may have different languages, customs and traditions, and many have been engaged in conflict with other groups for thousands of years. Then there is the geography and infrastructure of the island. The CIA World Factbook provides information on every country on the planet, and provides detailed information on various facets of the country like population and infrastructure. For Papua New Guinea, the eastern half of the island, the CIA World Factbook informs that there are 561 runways. Of those, only 21 are paved. So to fly there, you are flying into primitive conditions. Under the section for “Economy” the CIA World Factbook notes that “Papua New Guinea is richly endowed with natural resources, but exploitation has been hampered by rugged terrain and the high cost of developing infrastructure.” So you’ve got an island with rugged terrain that is difficult to cross, has very little infrastructure, is divided between two countries, and is home to thousands of different groups who don’t necessarily get along with their neighbors. The primary concern of the native population isn’t finding new species of fish, but rather just surviving. So it is kind of hard for ichthyologists to go exploring. You have to give kudos to these intrepid modern day explorers who manage expeditions to one of the last truly wild and unexplored frontiers on Earth, returning with new species previously unknown to science. Melanotaenia of New Guinea As mentioned, the Melanotaenia genus is the one that has caught and captured my interest. As detailed above, as of October 2013 the genus contains 60 species. Of these 60 species, 49 are endemic to New Guinea and the outlying islands, 10 are endemic to Australia, and one species, Melanotaenia maccullochi, is found in both. As I write this, there is some confusion regarding a fish that is currently known as Chilatherina lorentzi. In a paper published in April 2013, Phylogeny and biogeography of rainbowfishes (Melanotaeniidae) from Australia and New Guinea, Dr. Peter Unmack, Dr. Gerald Allen, and Dr. Jerald Johnson make the argument that Chilatherina lorentzi should actually be placed in the Melanotaenia genus rather than Chilatherina. However, as this has not yet been conclusively established, I have not included Chilatherina lorentzi in addressing the following. But what is really interesting about Melanotaenia and their relation to both Australia and New Guinea is the progression of discovery:
As you can see, it was possible to walk from the southern coast of today’s Tasmania all the way to the northern coast of current day New Guinea. And of course where you can walk, water can flow. Rivers flowed throughout the Sahul continent, and the predecessors of today’s rainbowfish swam in those rivers. As the ice age receded, the ice caps melted and the sea levels rose, once again separating the landmasses of Australia and New Guinea. But the rainbowfish remained in the now distant rivers, becoming separate but closely related species. (For those of you interested, Monash University in Melbourne, Australia has a project tracking the progression of the Sahul continent over the millennia as the oceans rose and fell. It’s really very interesting and you might want to check it out at http://sahultime. monash.edu.au.) Now modern day Australia is pretty well explored. Most of the species of rainbowfish living there have probably been discovered. Oh, there are still some places to go and things to find, but for the most part it has been pretty much explored and is a pretty hospitable place, at least compared to New Guinea. Why Hasn’t New Guinea Been Totally Explored? At 303,381 square miles (785,753 square kilometers), New Guinea is the world’s second largest island (Greenland is first at 822,706 mi2 [2,130,800 km2]), but is one of the least explored places on the planet. While New Guinea is less than 0.5% of the surface of the Earth, it has an estimated 5% to 10% of the total species on Earth… and many, many of those are unknown and undiscovered. Politically it is divided in two, with the eastern half of the island being a separate county, Papua New Guinea, and the western half comprised of two provinces of Indonesia. 20 November 2013

As is evidenced, only two new species of Melanotaenia have been discovered in Australia since 1980, while 36 species of Melanotaenia have been discovered in New Guinea in the corresponding time period. With a ratio of five species of Melanotaenia endemic to New Guinea for every Melanotaenia species endemic to Australia, and with the vast majority of new species of Melanotaenia being discovered in New Guinea since 1980, it is easy to see why anyone interested in Melanotaenia has to be focused on New Guinea. The IUCN Red List and CARES Preservation IUCN Red List of Threatened Species It is neither my intention, nor within the realm of practicality to give a comprehensive overview of the IUCN Red List of Threatened Species. For those interested in better understanding it, I refer you to their excellent and thorough website at www.iucnredlist.
org. However, to understand the relationship between the IUCN Red List of Threatened Species and the CARES Preservation Program Conservation Priority Species at Risk List, a basic understanding of both is required. IUCN is the acronym for the International Union for Conservation of Nature, the world’s oldest and largest global environmental organization with a stated mission to “influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable”. They have created an inventory for the global conservation status of species, both animals and plants, which is based on evaluating the potential of extinction of thousands of different species. It is a living document, with revisions of both the categories and criteria occurring over time. Presently there are nine categories into which a given species may be placed. They are:
Extinct:
A taxon is Extinct when there is no reasonable doubt that the last individual has died. A taxon is presumed Extinct when exhaustive surveys in known and/or expected habitat, at appropriate times, throughout its historic range have failed to record an individual.
Extinct in the Wild:
A taxon is Extinct in the Wild when it is known only to survive in cultivation, in captivity or as a naturalized population (or populations) well outside the past range. A taxon is presumed Extinct in the Wild when exhaustive surveys in known and/or expected habitat, at appropriate times, throughout its historic range have failed to record an individual.
Critically Endangered:
A taxon is Critically Endangered when the best available evidence indicates that it is facing an extremely high risk of extinction in the wild.
Endangered:
A taxon is Endangered when the best available evidence indicates that it is facing a very high risk of extinction in the wild.
Vulnerable:
A taxon is Vulnerable when the best available evidence indicates that it is facing a high risk of extinction in the wild.
Near Threatened:
A taxon is Near Threatened when it has been evaluated against the criteria but does not qualify for Critically Endangered, Endangered or Vulnerable now, but is close to qualifying for or is likely to qualify for a threatened category in the near future.
Modern Aquarium - Greater City A.S (NY)

21
Least Concern:
A taxon is Least Concern when it has been evaluated against the criteria and does not qualify for Critically Endangered, Endangered, Vulnerable or Near Threatened. Widespread and abundant taxa are included in this category.
Data Deficient:
A taxon is Data Deficient when there is inadequate information to make a direct, or indirect, assessment of its risk of extinction based on its distribution and/or population status. A taxon in this category may be well studied, and its biology well known, but appropriate data on abundance and/or distribution are lacking. Data Deficient is therefore not a category of threat. Listing of taxa in this category indicates that more information is required and acknowledges the possibility that future research will show that threatened classification is appropriate.
Not Evaluated:
A taxon is Not Evaluated when it has not yet been evaluated against the criteria.
These are basic descriptions of the categories, and that for a species to be placed in one of these categories there are specific criteria that must be met. CARES Preservation Program
CARES Preservation and Melanotaenia
The IUCN Red List has several sub-divisions where focus is given to a different area of biological diversity. One of these areas is freshwater habitats, which include fishes, mollusks, reptiles, insects, plants, and mammals. It is in this area where the IUCN Red List and the CARES Preservation Program have their overlap. As of October 2013, the CARES Preservation Program Conservation Priority Species at Risk List contains 561 species divided amongst 11 categories. Of these 561 species, 231 have the IUCN Red List as the primary or shared authority for the risk classification. However, this changes slightly with relation to Rainbowfish. One of the 11 CARES Preservation Program categories is “Rainbowfish”, containing 38 listed species, or 6.77% of the total number of all species listed in the program. But of the 38 species, 27 have the IUCN Red List as the authority.
Now the CARES Preservation Program Conservation Priority Species at Risk List groups all rainbowfish (that is all Sahul species from both the Melanotaeniidae and Pseudomugilidae families, and all Madagascar rainbowfish from the Bedotiidae family) under the unified heading of “Rainbowfish.” Of the 38 species contained in the “Rainbowfish” section of the CARES Preservation Program Conservation Priority Species at Risk List, only 6, or 15.79% of the 38, are Melanotaenia species.
The 6 Melanotaenia species listed are; • • • • • •

Modern Aquarium - Greater City A.S (NY)
One of the six fish, Melanotaenia eachamensis, is native to Australia and as such, I won’t examine it here. (I will say that the story of why it is a vulnerable species is very interesting, and for those who are interested, I would direct you the excellent summary of the species provided by Adrian Tappin at his Home of the Rainbowfish website, http://rainbowfish.angfaqld. org.au/). I also find it interesting that the distribution of known species of Melanotaenia between New Guinea and Australia is at roughly a 5:1 ratio, and the distribution of Melanotaenia species on the CARES Preservation Program Conservation Priority Species at Risk List is exactly a 5:1 ratio between New Guinea and Australia… Of the five New Guinea Melanotaenia species that are on the CARES Preservation Program Conservation Priority Species at Risk List, two (Melanotaenia
lacustris and M. oktediensis) are from the country of Papua New Guinea, and the other three (M. arfakensis, M. boesemani and M. parva) are from the Indonesian province of West Papua.
In Part 2 we'll take a look at each of these fish and see why they're on the list.

scale replica of the Monitor was in the back of the tank. I failed to recognize the ship when we first entered the main tank, but then it dawned on me that this replica was a recreation of the wreckage of the Monitor in its current state. The model was fifty feet in length, so I assume that the original Monitor was 150 feet long, which seemed to me to be rather small, but I guess that half the length of a football field is not too small. I understood that this would be the closest that I would ever come to personally viewing the original Monitor. Still, the model gave me an historical perspective, even though I knew that if I came across the real ship on the seafloor I wouldn‘t know what I was looking at. Sandbar shark, Carcharhinus plumbeus. These specimens were four to five feet in length. They mostly circled the tank continuously and ignored us, but every now and then one swam close to inspect us. I did the same with my camera.

I was too buoyant and had difficulty submerging, so Jason snapped a two pound weight to my shoulder harness, and down I went. Laaron, a young woman transplanted from California, held a four or five foot pole made from white PVC, with striped tape to fend off aggressive sharks. She also had a small waterproof camera, and took photos of us and the fish. Later, I asked her to clarify her name. “Aaron preceded by an L,” she replied. When we had entered the water, Jason monitored us from a catwalk above the tank. While Laaron was to assist us in case of an emergency, Jason’s dive briefing explicitly stated that if Laaron had difficulty, we were expected to assist or rescue her—not that we wouldn’t help a fellow diver. It was the first time that we have been specifically asked to save the dive professional! As in most sports, there is camaraderie among divers.
Sand Tiger shark, Odontaspis taurus.
The model was the home of the nurse shark. It never left the inside of the hull, but there were openings to look inside and see the shark. I wondered if any sharks lived in and around the real Monitor. We have seen many nurse sharks in a similar state of relaxation. Nurse sharks average five to nine feet in length, but can grow to fourteen feet. I couldn’t see the whole shark, but estimated it to be at least seven feet.

A fully grown specimen is eight feet in length, but it can grow to ten or eleven feet. They swim with an open mouth full of long curved teeth, and can be found inhabiting North Carolina’s offshore wrecks. Their color is grayish brown. They are not considered to be a threat, but we would be with them in a very confined space. Before we entered the main tank, I did ask Jason if the sharks had been fed that day. He replied that they were fed the day before. “When are you feeding them today?” I inquired. He responded that they are fed three times a week, and would not be hungry today. We kept that assurance in mind from the time we entered the tank until we made our ascent.

residents, it also occurs on the offshore island of Nosy Boraha. The northern range limit is yet to be determined. (Loiselle, 2011) Diet
P. sp. ‘fony’ are crepuscular (more active during dawn and dusk), prefer taking their food (prey) from the water’s surface, and are not fussy eaters. Most cichlid pellets and sticks are taken with gusto. Mine have shown no interest in vegetable fare, though all predators get some veggies by way of whatever is in their prey’s digestive tract, so a high quality pellet with some vegetable content is a good choice as a staple. They will gladly eat feeder fish, though I prefer not to use them due to the danger of introducing Ichthyophthirius multifiliis, commonly referred to as ich, Oodinium pilularis or related species, or other parasites (remember their susceptibility to skin infections). Commercial foods these days are good enough that live feeders aren’t nutritionally necessary, and freezedried krill and the occasional bug keep them in good spirits. I have to put in a plug here for Hikari Massivore Delite™ pellets. All my big fish love them. Their only drawback is that pellets missed on the way down will not necessarily be retrieved, so I reserve these Modern Aquarium - Greater City A.S (NY)

sinking pellets for when I have time to individually hand-feed. Sexual Dimorphism Sexually dimorphic, the P. sp. ‘fony’ males I have seen usually have a darker (nearly black) base color than females, which lean more toward brown. The spots of the females seem to me to resemble spangles rather than spots, though this could be because of the lighter base color. As with many cichlids, color can vary because of mood and other factors, so don’t get too cocky when using this method to guess sex. While most of the males I’ve seen have spots that vary from white to blue, I’ve also seen individuals, clearly males, with a brownish base color and yellowish spots. The males grow larger than the females, and can develop a pronounced nuchal hump. When mature, both sexes are intolerant of conspecifics. Dominant behavior may be expressed by direct attack, or by not allowing subordinates to feed, particularly from the surface. Housing In my experience, keeping a fully grown P. sp. ‘fony’ pair without a divider requires at least a 6-foot tank, with some good hiding places for the female. Both

(known) spawnings by my fish have been in a 55-gallon. In a 4-foot tank a divider is not optional. Interestingly, and somewhat misleadingly, the male is not always overbearing to the female. Even when not spawning, they can give the appearance of affection, even tenderness, often ‘lying down’ together next to a rock, or in a hollowed-out area of the gravel. However, the female needs a safe retreat when that mood ends. For a time I was keeping a pair in a 125gallon tank along with a pair of Herichthys carpintis. When the behavior of the male P. sp. ‘fony’ became too oppressive, the female often took refuge with the H. carpintis pair where the male P. sp. ‘fony’ would not pursue. Spawning Attempts My original pair spawned twice. The first time, they seemed confused about what to do next, and finally ate the eggs. The second spawning failed at my hand– literally. I didn’t realize they had spawned, and I smushed the eggs while attempting to adjust one of the filter intakes. Their eggs are produced in a gelatinous mass which they may or may not attach to a handy surface; in this case the handy surface was the side of the intake, and I didn’t see it until too late. They didn’t spawn again, and last year both became gravely ill—the first symptoms were the familiar fluffy patches on their skin. The male pulled through, but I wasn’t quick enough to save the female. At a recent auction I picked up another pair from GCAS member Jeff Bollbach, so we’ll see what happens with them.
that comparison. Yes, the youngsters will display that puppy dog enthusiasm when you come near the tank, but to me it has always seemed to come with a more mercenary edge (where’s that food?) than A. ocellatus project. In a community tank– even a spacious one–P. sp. ‘fony’ has always seemed more concerned with food and social rivalries than with anything else. Well, of late I have been forced to reconsider that view. While subduing yet another stubborn columnaris outbreak (you’d think that such combative fish would have less sensitive skin), I put the big male in a 55-gallon tank, alone except for a couple of catfish. Once again I was reminded that fish behavior depends to an enormous extent on how you are housing them. With no female to attend to and no other potential competitors to try to dominate, this big guy suddenly became a warm and friendly ‘people person.’ It’s been a good reminder. I think that sometimes, particularly with cichlids, we can become so fixated on the breeding and family life interactions that we can forget to just enjoy having a fun pet to come home to–a role that P. sp. ‘fony’ can fill admirably. Also, remember the crepuscular activity cycle? Well, for those of you who go off to work at daybreak and return as the sun is going down, your P. sp. ‘fony’ will be up and alert while you’re getting ready to leave in the morning, as well as when you return in the evening. Most of my other

Satellite Spawners A series by “The Undergravel Reporter” In spite of popular demand to the contrary, this humor and information column continues. As usual, it does NOT necessarily represent the opinions of the Editor, or of the Greater City Aquarium Society.
ver heard of “satellite spawning?” It’s a mode of reproduction used by Midshipman fish. They belong to the genus Porichthys (toadfishes) and came to my attention from a post on the Mother Nature Network titled “Mating fish keep British town up all night”1
E
Midshipman fish, of which there are currently 14 recognized species, have three sexes (or, depending on how you want to look at it, two and a half sexes): Females, Type I males, and Type II males. The reproductive organs of Type II males are seven times larger than those of Type I males. On the other hand, Type I males are eight times larger in size, and have much larger vocal organs than Type II males. Type I males use their vocalizations to attract females to the nest with hums that can last up to an hour. Type II males then “sneak” into the nests (because they look much like females) and fertilize the eggs. (This behavior is referred to as cuckoldry or satellite-spawning.) Mother Nature Network reported that residents in the British town of Hythe have complained to the local council, saying they’ve had to leave the area just to sleep because of nocturnal noises. The Scottish Association for Marine Science thinks the noises are coming from male midshipman fish, whose mating ritual creates a sound of such low frequency and long wavelengths that it carries through the ground and into homes.
a Midshipman fish According to Wikipedia2, “Mating in midshipman fishes depends on auditory communication. Male midshipman fish produce several different vocalizations while females only make grunts in non-breeding situations.”

And, this isn’t the first time midshipman fish have interfered with people’s sleep. Last year, the mysterious sound was so loud that it woke Seattle residents in the middle of the night. I think I’ll just stay with my Trichopsis vittata (croaking gourami).
