September 2011 volume XVIII number 7
Series III ON THE COVER Our cover this month features Pterois volitans, popularly known as the lionfish. Long a favorite of saltwater fishkeepers with a taste for exotic beauty with an element of danger, the venomous lionfish isn't so welcome in its newly adopted range, the southern Atlantic coast of the U.S.A.

From the Editor by Dan Radebaugh he FAAS Article Competition winners have been announced! Actually, they were announced in time for last month’s issue, but the annual Silent Auction didn’t seem to be the best venue for presenting awards, so we held off to this month. Modern Aquarium once again did very well, sweeping several categories, including the Author of the Year category. Al Priest, our FAAS delegate and former Editor of Modern Aquarium, tells us about the contest and the winners, on pages 8 & 9. Congratulations to all our authors on another fine showing, and a special congratulation goes to Al for being named FAAS Author of the year! The subject of our cover photo this month, the lionfish Pterois volitans, is also the subject in this issue of the latest in a series of articles by Steve Sica. Steve, who tied for Second Place along with Sue Priest in the FAAS Author of the Year category, has written several articles documenting the spread of P. volitans that have graced the pages of Modern Aquarium going back to 2008, my first year as Editor. Steve has not only kept us abreast of this fish’s adventures in the New World, he has provided us with some beautiful photographs in the process. As a side-note, I came upon a news item regarding P. volitans in the current issue of Aquarium Fish International. A study done by the University of Queensland (Australia) has shown that in protected (no fishing) areas of the Caribbean, large groupers such as the Nassau Grouper Epinephelus striatus are able to effectively control the otherwise almost predator-free lionfish. Outside the protected areas, the groupers are too overfished to have a significant effect. The scientists recommend a drastic reduction in the harvesting of groupers until their numbers can build up sufficiently to be an effective control on the lionfish population.1 Later on in the issue, in an article with a complex title, Al Priest tells us about a couple of small bettas with a complex of their own. Sue Priest reviews a new book on aquarium plants, and I contribute a brief article on fish tuberculosis, a subject I’m sure none of us is eager to learn too much about. The Undergravel Reporter reviews the new Animal Planet show Tanked!, and the Fin Fun puzzle is “The Colorful Cory.” “MA Classics” this month celebrates the FAAS awards by presenting a First Place winner from 1998 by Joe Ferdenzi, "Five Days in the Life of Corydoras adolfi,"along with a cartoon by Bernie Harrigan, who

was also a First Place winner that year in the Cartoon category. Speaking of cartoons, the winning caption in last month’s Cartoon Caption Contest is shown on page 6, and the new cartoon challenge is on page 7. We didn’t have too many entries last month―maybe everyone was too involved with their winnings in the Silent Auction. To make entering easier, this month we’ll distribute entry sheets along with your Modern Aquarium issues. Just fill in your name and a caption, and turn it in to us before you leave the meeting. Good luck! * * * Remember, as always, we 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 fax it to me at (877) 299-0522, email it to gcas@earthlink.net, 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
s difficult as it sometimes is for me to remember this, there are fishkeeping periodicals besides Modern Aquarium. One of these is Aquarium Fish International. I had just about decided to let my subscription to this expire, but as there lately has seemed to be a slight but noticeable up-tick in quality, I went ahead and renewed. While perusing the latest issue (October) the other night, I saw a couple of items of interest. One of these I’ll let our Editor talk about in his column. The one I’ll address here was headlined, “San Francisco Considers Tropical Fish Ban.” It seems that the city, prodded by its Commission of Animal Control and Welfare, is considering a ban on the sale of all animals commonly kept as pets. This proposed legislation is purported to be for the purpose of “cracking down” on puppy and kitten mills by “discouraging impulse buying of animals that will end up in shelters.” Fish are to be included “because most fish in aquariums are either mass bred or taken from the wild.” Now while eliminating so-called puppy mills may be a laudable goal, this approach is not laudable. A couple of years ago (see
Modern Aquarium, May, 2009, pp. 2530), the Humane Society of America tried to get a bill (HR 669) through Congress that also had the apparent goal of ending pet ownership―but in the entire country. After pet owner groups realized what was going on and rallied against the bill, it was crushed in Congress. This new action in San Francisco smacks of the same authoritarian mindset as that defeated bill, and seems to signal a new strategy―divide and conquer. Maybe its proponents can slip it through in San Francisco and then set their sights on other cities, effectively avoiding national petowner organizations (and therefore organized opposition). Responsible pet owners and animal lovers these days need to be very careful and vigilant about what sort of legislation is being foisted upon the public, and very wary of what’s behind noble sounding marketing messages such as “cracking down on puppy mills.” If you look at the actual proposals, you might find that the true aim is to “crack down” on all of us who keep pets.

The G.C.A.S. Proudly extends a most Warm Welcome to
Our Guest Speaker Mark Soberman Speaking On Keeping and Breeding Corydoras by Claudia Dickinson rom the time he was a young boy growing up in Sunnyside, Queens, Mark Soberman was fascinated by all aquatic life. Occasional visits to a neighboring apartment were savored, as here oldfashioned fishbowls, filled with the allure of guppies and live plants, lined the walls. At the age of ten, Mark received his first tengallon aquarium from another neighbor with like interests. The tank came equipped with all of the fittings, which included an old Supreme piston pump, and two fish that Mark remembers well—one kissing gourami (Helostoma temmincki) and one blue gourami (Trichogaster trichopterus). Encouraged by the full support of his parents, Mark’s passion flourished. It was a memorable day when his father took him on an excursion to Brooklyn for the purchase of his first thirty-gallon tank. His bedroom soon held this plus three more tanks, which housed everything from guppies to discus, and even saltwater fish! Attending college at the State University of New York at Brockport, where Mark went on to get his Masters, put fishkeeping on a brief hiatus. In 1984, the newly wed Mark and Robin Soberman went for a day’s outing at the racetrack, where Mark won an Exacta. Well, he immediately drove to Tropical Fish Supermarket with his winnings! The store’s proprietor, Charlie Murphy, assisted Mark and got him back into

full swing with a twenty-nine gallon setup. Mark’s hobby had been rekindled and it expanded, until eventually he was able to create his dream of a fishroom. Putting in long days as sales manager of a dental supply company, he can now rejuvenate in this basement room, immersed amongst the fish and bubbling waters of forty aquariums which range in size from 10 to 125 gallons. With Mark’s precise and meticulous style, the neat rows of tanks shine with healthy, vibrant, and prolific fish. Although Mark specializes in breeding Corydoras catfish species, over the years he has also bred cichlids, killifish, characins, and livebearers. He is involved in a variety of projects, his most recent being to attempt the breeding of some of the riverine Synodontis species. One can always spot Mark’s fish in a show, most particularly if they are catfish, for they are certain to stand out from the rest due to the brilliant colors, large size, and striking beauty. His walls and shelves are filled with numerous trophies in recognition of his talents. Mark’s reputation travels far and wide for his ability to condition his fish and provide appropriate conditions for the spawning of the most difficult species.

With a deep interest in the history of the aquarium hobby, Mark has a remarkable collection of antiquarian literature and ephemera that joins numerous aquatic artifacts. This is displayed in special bookcases, with extra space available for his insatiable desire to discover yet another rare book. The premier “All Aquarium Catfish Convention,” held in 2004, began a new journey in Mark’s outstanding career as he served as a panelist on the Corydoras Forum and united with fellow catfish experts from across the world. Since then he also did a workshop on catfish aquascaping in 2008 and gave the banquet catfish quiz in 2010. As a result of his acquaintances there, he now serves in the distinguished role of moderator on the highly respected forum, “Planet Catfish,” www.planetcatfish.com, and he is a member of the British Catfish Study Group. In 2006, Mark was invited back to the biannual convention to speak on African catfish. Involved with the formation of the North American Catfish Society, as well as other catfish organizations, Mark is also an author, having written
articles for Tropical Fish Hobbyist, Modern Aquarium, and several catfish journals. A highly sought after speaker, Mark has traveled extensively, giving his programs across the country as well as in Bermuda for the Bermuda Fry-Angle Society. A member of the Greater City Aquarium Society since 1984, Mark has served on its Board of Directors for more than 15 years. Named to Greater City’s Joseph Ferdenzi Roll of Honor in 1998, he is also one of the club’s top lifetime breeders. Aside from the GCAS, Mark is a member of the Long Island Killifish Association (LIKA), the American Killifish Association (AKA), and the American Cichlid Association (ACA), as well as the aforementioned British Catfish Study Group. It is with great pride and warmth that we welcome Mark tonight as he shares his extensive knowledge and experience with Keeping and Breeding Corydoras.

The 2010 FAAS Publication Awards by ALEXANDER A PRIEST embership in the Federation of American Aquarium Societies (FAAS) is open to aquarium societies in North, Central, and South America. Formed in 1973 to fight against a proposed federal law which would have severely restricted the importation and transshipping of tropical fish, FAAS is now primarily a virtual, web-based organization providing information to help societies run better. FAAS has a Publication Award Program to recognize the efforts and contributions made by aquarium societies and their members through their publications to educate their members, and to promote the hobby. Articles and artwork from non-commercial publications during a calendar year are submitted for judging. There are 30 categories for consideration. Some awards offer a junior level competition based on the age of the individual author. Greater City is a FAAS member, and participates in the FAAS Publication Awards program. The results of the judging of last year’s articles is below. For the 2010 publication year, there were 248 entries. All awards for all participating societies are listed here. For specific details (such as the title of award winning articles), go to https://acrobat.com/#d=ZkmQguqlM-DyryJpSSAf*A (this information will soon be on the official FAAS website at www.faas.info). While Greater City authors did well, we could (and should) have done better. Look at the 2010 Article Index in the March issue of Modern Aquarium and you’ll see no articles on killifish, cyprinids, plants, loaches, or rainbowfish, and that’s just to name a few of the areas I know some of our members are interested in. So, please consider sharing your interest and knowledge by writing articles.

A Simple Complex The “Albimarginata Complex” Betta Albimarginata and Betta Channoides by ALEXANDER A PRIEST - photos by the author
A
ccording to Wikipedia “A species complex are two distinct species. If the fish in both tanks is a group of closely related species, where were somehow combined into one group, I doubt the exact demarcation between species is that I could separate them back into two distinct often unclear or cryptic owing to their recent and species populations with 100% accuracy. They usually still incomplete reproductive isolation. look and act very much alike, and their care is ...Species complexes are more common among identical. So, this one article will essentially be plants, but animal examples exist, such as the about the “Albimarginata Complex” consisting of dog-wolf-coyote complex (the genus Canis) and the two species: Betta albimarginata and Betta cobras (genus Naja).1" The International Betta Channoides, both from Indonesia. When I first Congress currently shows 11 different complexes encountered Betta albimarginata, they were known for the genus Betta.2 The placement in a particular as Betta albimarginata sp. malinau (what was to Betta complex appears to be determined mostly by later become channoides was, at that time, called physical similarities. For example, the Picta Betta albimaginata sp. pampang). Complex consists of five small mouthbrooding They are small, both sexes as adults being species: Betta falx, Betta picta, Betta pallida, Betta slightly less than 2 inches, Total Length. Both are simplex, and Betta taeniata. The two species that currently make up the Albimarginata Complex: Betta albimarginata and Betta channoides are certainly similar in appearance. (There has been discussion about breaking albimarginata into three species based upon their local data, but so far this has not happened.3) If you do an Internet search for either species, you will find many people Male Betta albimarginata questioning the difference between them, basically asking “Which species do I have?” paternal mouthbrooders, with males incubating the eggs for about two weeks before releasing the fry, Betta channoides are slightly smaller, darker, after which the parents provide no additional care. and more intense in color, have a more blunt head, As long as the parents are well-fed, predation is and have less black around their gills than Betta rare. I recommend removing the parents after a albimarginata. At least one person indicated that spawning simply because it’s easier to care for the the most reliable way to tell the difference is by the fry. I always have an active sponge filter in every color of the fry, with the fry of Betta channoides tank. A sponge filter that has been in use for three being grey and those of Betta albimarginata being or more months will usually have infusoria and black.4 (I have not found this to be true.) microorganisms upon which the fry can graze. In I have a tank of each, which I acquired them addition, the fry can be fed microworms and finely from a reliable exporter who claims that what I have ground flake or pellets (I use a mortar and pestle).

Male Betta channoides Since this is a relatively small fish, both the number of fry per spawning and the size of the fry are small, with 30 to 40 being the absolute maximum number you should expect to see. Females initiate the spawning and will often show their readiness to spawn by displaying vertical body stripes (somewhat similar to those of female Betta splendens who are ready to spawn). Both species do best in soft, acidic water with a pH from 6.0 to 6.8, and with a temperature from 76E to 82E F. Betta species are primarily carnivores, so live or frozen worms and brineshrimp are the best foods for conditioning them for spawning. A tightly covered tank (these are jumpers!) with plenty of caves should be provided. (Not only are these relatively shy fish that appreciate hiding places, but the males will also use those caves while holding eggs.) While plants are not disturbed by either species, they prefer a low-light environment. That, coupled with soft acid water, somewhat restricts your choice of plants. Plants in the genus Anubias, as well as Java Fern can usually survive under these conditions.
The generally accepted common names for these species are: for Betta albimarginata, “Whiteseam Fighter” ( A l b i = w h i t e , Marginata=border, referring to the white stripe on the border of the anal fin), and for Betta channoides, “Snakehead Fighter” (Channoides = resembles channa, or snakehead). Also, as I mentioned, Betta channoides are darker and have more intense color, so other common n a m e s f o r Betta albimarginata and Betta channoides are, respectively, “Strawberry Betta” and “Cherry Betta” (supposedly, “cherry red” is darker than “strawberry red” -- who knew?). Males of both species are brightly colored (with red bodies, as indicated above). Females of both species are drab gray. When ready to spawn, males become even more intensely colored. While you can house more than one pair in a tank, usually only one dominant male will exhibit full color. These species are generally timid, nonaggressive fish, They can be housed with other small peaceful fish having similar water parameter requirements; but they do best (and are more likely to spawn) in a species-only tank of their own. The males of both species, while small, are brightly colored and very attractive. Males will get territorial when brooding, and females tend to be more aggressive, especially towards other females. I would rate them “moderate” with respect to the degree of difficulty to keep them, mostly because maintaining a soft, acid tank requires a bit more effort.

Grand Cayman’s Lionfish Story and Photos by Stephen Sica
S
pring is a time of year when Donna and I enjoy traveling, and more often than not, it’s a trip to the Cayman Islands. When Donna read that the Cayman government finally sank the USS Kittiwake in January, she proclaimed that we had to dive this shipwreck before it is destroyed by a hurricane. “Okay,” I responded; “book it Donna!" and she did. The Kittiwake is a former United States Navy submarine rescue tender that had been decommissioned and eventually donated to the Cayman Islands as a dive industry tourist attraction. The ship is exactly 251 feet in length with a beam of 40 feet. For many years it was in mothballs in the state of Virginia, before it began the process of being environmentally cleaned and prepared to become a reef. Then it had to be towed from Virginia to Grand Cayman for its “inaugural” sinking, which took place on a patch of white sand just offshore of the trendy and touristy Seven Mile Beach on the west side of Grand Cayman Island, where most of the hotels are located. The Kittiwake was the first United States Navy ship that was donated to a foreign country under America’s artificial reef program. We arrived on Grand Cayman on May 20th. After dinner that evening I unpacked our gear. We were looking forward to our 8:30 pickup the next morning. We were booked for two morning dives, and then the Kittiwake dive in the afternoon. We were apprehensive, because it was going to be a strenuous day, with six additional dives planned for the following three days. Saturday morning found us riding with a couple from Minnesota in a rickety van down the back streets
Modern Aquarium - Greater City A.S (NY)
of Georgetown, while a parade took over the main streets. We arrived at the dive shop, completed our paperwork, and took our gear to the boat that was tied up at the dock a short walk from the door. The crew of three helped us haul our gear aboard, and soon we were heading out to sea with seven other divers. Most dive outfits ask the divers which sites they have already dived during their current stay, in order to try to avoid repetitive dives to the same location. Unlike Donna, who prefers wide open spaces, most divers like to swim through coral canyons, overhangs and caves. The first dive usually has narrow walls and overhangs, and is the deeper dive. L i o n f i s h generally prefer cavelike protection. All of the lionfish that I have observed in the Cayman Islands were found at depths of forty to ninety feet, and protected by coral―sort of in their lair. I have very rarely seen a lionfish swimming in open water, and never in the Cayman Islands. In the Bahamas I observed some lionfish in the open on the reefs―usually at fifty feet or deeper. These would hover in one place―sometimes out in the open, but usually in their lair. During the course of our trip we made nine dives in four days. As a result, it was difficult to keep track of all of the lionfish that we saw. On some dives I saw two or three that I would mention to Donna while we were writing our dive log, which I usually did during dinner while we were waiting for our meal. Donna takes notes after our dives to keep our recollection fresh and to help me recall anything worthwhile or unique. Donna would say, “Didn’t

you see the big one in the nook over there, or the one with the long spines over here, or the two together on the ridge by the rock…” Needless to say, between us we saw quite a few lionfish, but contrary to the rules of the buddy system, I often lag behind taking photos, while Donna swims ahead close to the divemaster. Often we see different things, and it seems that there were just too many lionfish to keep track of. The only dive where neither of us saw a lionfish was the Kittiwake shipwreck. Next to the ship was a large tract of garden eels. There also were numerous tracks in the sand, and at the end of each was a juicy conch. After a long day of diving, while we were waiting for our ride back to the hotel, we studied the bulletin board next to the dive shop doorway. There was a white chalkboard that I photographed. A few weeks later I was reading the June 2011 issue of Sport Diver magazine. Its “Dive Briefs”

section on page 10 was titled, “Deadliest Catch: Lionfish.” It stated that 53 was the highest number of juvenile fish found in the stomach of a single lionfish. Furthermore, the species has a stomach that can expand up to 30 times its normal size. Their diet includes virtually any small fish, shrimp or mollusk that you can name. In one month a single lionfish can lay 30,000 eggs. If all of these eggs hatched and matured into adult lionfish, these fish could lay 200 million eggs in two more months, and 8.1 quintillion eggs in three months. I do not know the magazine’s source of this information and I cannot vouch for its accuracy, but I believe that it is probably safe to say that the lionfish is a prolific reproducer! While all of the lionfish (to the best of my
recollection) that I have photographed have had brown to reddish brown stripes, I did observe a single smaller specimen that had black stripes. I viewed it from as many angles as possible to see if its dark coloration was an optical illusion or some such, but it sure looked black to me. I have included a photograph of this specimen, along with other photos of several of the other lionfish that we observed. I estimate that Donna and I saw at least 25 lionfish between us. It is safe to say that the lionfish epidemic is fully in attack mode. Will man be able to thwart this abnormal force of nature? I surely hope so, but I am beginning to have doubts. Only time will tell. Stay tuned for future updates.

MA Classics
In this installment of our series showcasing articles from past issues of Modern Aquarium, and mindful of the FAAS Publication Awards listed elsewhere in this issue, I looked through some past FAAS Award-winning articles, and found this one from 1998. This is the first article from Modern Aquarium Series III that we have featured in "MA Classics." In fact, it isn't only an article—it's an article and a cartoon! Immediately following Joe Ferdenzi's 1st Placewinning article on spawning Corydoras adolfoi is a cartoon by Bernie Harrigan, who won 1st Place in the Cartoon category that year (among others). So we get two blue ribbons for the price of one!

antibiotics. The usual treatment is kanamycin, but often two different antibiotics are used over a three month period.3 The thick, waxy coat of the bacteria, along with the “clumping” that occurs in some strains, also makes them resistant to disinfectants.5 If you suspect that one of your fish has died from this pathogen, the recommended sterilization procedure is to first thoroughly soak the tank and its contents with chlorine bleach. Once the bleach has been neutralized and dried, soak or spray with alcohol (65-90%) for 15 to 30 minutes.5
Symptoms of fish tb • • • • • • • • •
loss of appetite fish remains in seclusion and out of sight rapid breathing (respiration) eyes appear to be cloudy or “popping out” fish lies on its side near bottom of aquarium stomach of fish appears to be sunken whitish blotches on exterior degraded and frayed fins distorted, "bent" spine
As experienced aquarists will recognize, the problem with these symptoms is that none of them, either individually or collectively, is unique to fish TB. Even the characteristic "bent spine" can have other causes, such as a deficiency of vitamin C. Causative organisms • • • • • •
Mycobacterium piscium Mycobacterium platypoecilis Mycobacterium anabanti Mycobacterium fortuitum Mycobacterium salmoniphilum Mycobacterium marinum Betta showing advanced lesion.
This list is by no means complete. There are thought to be around 50 other related organisms that can cause disease, living in all manner of environments. At least one researcher is using zebra danios to research the genus and hopefully help find a cure for human TB.4 Prevention The organisms that cause fish TB are ubiquitous, and thrive especially in warmer water. The key to preventing this disease lies in good basic husbandry practices—keep your fish healthy! Just as in humans, a fit immune system is the best disease preventative. Good food in the proper quantity, good filtration and frequent water changes to maintain beneficial water quality, keeping stress to a minimum—all these basic practices are important for keeping your fish desease free. Quarantine, while generally a good idea for new acquisitions, is not effective for fish TB, as this disease can take years to manifest.
Traditional aquarist strategies, such as adding salt and raising water temperature, are a waste of time with this disease, as these bacteria occur in both fresh and salt water, and thrive in warmer temperatures. Some sources say that treatment of this disease in the aquarium is so difficult, and a positive outcome so unlikely, that it’s best to go ahead and euthanize the infected fish, as well as its tankmates, followed by drying out and disinfecting the tank. Other sources however do recommend treatment. According to National Fish Pharmaceuticals, “Kanamycin + Vitamin B-6 for 30 days is the most effective treatment that we know of for tuberculosis. The fish should be quarantined during treatment time. Liquid baby vitamins found at your local pharmacy are a good source of vitamin B-6. One drop per every 5 gallons of aquarium water is sufficient. Replace the vitamins according to how much water is changed in the tank during treatment time.”1
While aquarists rarely contract this disease, it does occasionally happen. There are some precautions you should consider, especially if your immune system is compromised in any way. Avoid starting water siphoning with your mouth. Don’t let any broken skin come in contact with the water. If you have broken skin on your hands or arms it’s probably wise to wear protective gloves when putting your hands in the tank. 20

Conclusions Fish tuberculosis—more properly fish mycobacteriosis—is a potentially serious condition. Fortunately, while the causative bacteria are common in the environment, human infection is relatively rare. However, if you do happen to be one of the unfortunate few who do contract the disease, action is required. The first signs of an infection are usually skin lesions or a rash. If you suspect that you may be infected, a visit to a dermatologist would probably be a good first step. Along with a description of your symptoms, do mention to your physician of choice that you are a fishkeeper, and that you're concerned about the possibility of an infection involving M. marinum.
Probably your doctor will want to take a tissue sample for biopsy, and for sensitivity testing to determine the best antibiotic choice should one be necessary. Don't be afraid to ask questions. If your physician doesn't seem to be familiar with the disease, or doesn't seem to be taking you seriously, don't hesitate to get another opinion. Be an informed patient. Remember though, your odds of contracting this disease are quite low, so if your doctor assures you that you don't have it, you can probably believe him (or her).
