From the Editor by Dan Radebaugh


ell, here it is nearly summer, both by the calendar and by the temperature, and some of us (not me) are getting ready to move some of our fish to outdoor quarters until Fall. Speaking from some experience, this is a great way to get your fish to put on some size, color up gorgeously, and in some cases spawn, where they might not readily do so indoors. Of course there are attendant risks – unexpected cold snaps, neighborhood cats, dogs, raccoons, and children, but by and large it’s a pleasant way for the fish hobbyist to justify being outside. I happened upon an article on this subject in an old issue of Modern Aquarium, written by Jack Oliva, a name I have heard Joe Ferdenzi mention, but who was here at Greater City before my time. I’ve used it this month as part of our MA Classics series. The article is titled “I Raise Tropical Fish in my Bathtub,” and I’m sure that more than a few of us have had that thought flit through our minds on more than one occasion. In fact, one of my sisters used to keep goldfish that way, though that was not the bathtubs’ primary purpose. She used these bathtubs as water troughs on her horse farm, and the goldfish were in there at least in part to eat any mosquito larvae that took up residence―Florida has no shortage. Also, the fish were just neat to have there. There were two or three bathtubs per pasture, right by the fence where they were easy to refill. The fish lived in those tubs yearround, with only a few losses to predators. It was only just before she finally sold the farm that the raccoons finally pretty much cleaned them out. While it may have been the end for most of those goldfish, for the tubs it was a different story. They were old bathtubs―I don’t even recall now (if I ever knew) where she got them, and she learned that if she had them re-porcelained, they could be sold for a surprisingly large sum. I wonder what Jack Oliva did with his old tub when its fishkeeping days were done. Staying with the reminiscent mood for a moment, in “Wet Leaves” this month Sue Priest reviews Ask the Fishkeeper, by Mark Morrone, whom some of you may remember from a television show called Petkeeping With Mark Morrone. The show can still be seen in reruns on some local channels, and Joe Ferdenzi tells me that Mr. Morrone owns a pet store in Rockville Center. In “A Touch of Gold,” Al Priest tells us about keeping and breeding Betta midas, a newly discovered


species from Borneo, and along the way updates our knowledge on some of the finer points of managing low-pH water chemistry. Elsewhere in the issue, Steve Sica treats us to a photo travelogue of “Grand Cayman’s North Sound,” while Claudia Dickinson, our American Cichlid Association delegate (among other duties) treats us to a new installment of “Cichlidically Speaking.” Claudia also contributes photos from last month’s meeting in “Through the Lens,” introduces this evening’s speaker, Mark Soberman, and reminds us in “Enriching Lives” that we must remain alert to the political world and its effects on matters of concern to us, both as fishkeepers and as citizens. The Undergravel Reporter explains to us why he hasn’t yet become rich, and the issue ends with the popular puzzle, “Fin Fun.” We need more articles! Remember, 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, 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


irst of all, welcome back to the Queens Botanical Garden! No, it wasn’t all a dream―we were planning to meet this evening at the Bronx Zoo, as guests of fellow GCAS member and Zoo Director Jim Breheny. The fact that we are here “at home” this evening has a great deal to do with the current financial situation of all our institutions such as the Zoo, the New York Aquarium, and the Queens Botanical Garden. Having already suffered major funding cuts last year, they are once again in line for drastic cuts by both state and local government. Clearly, there is no quick or easy solution to this funding crisis. Probably every one of us has directly felt the impact of the financial meltdown of the past couple of years, and we all understand that things aren’t going to recover overnight. Meanwhile, no one wants to, or should have to bear the burden of funding cuts alone or disproportionately, so every group, cause, or organization that depends on public funding is mobilizing to defend its lifeblood. This is natural, and is the way our government works. It is up to us to make sure our elected representatives know what we value, and what we expect of them. Yes, I know it’s a drag and a bit of a cliché to “write

your Congressman,” but if we don’t tell them what we’re thinking, how will they know? So write, call, email. Do what you need to do to let the people you elected know what you think. The animals, fish, trees, and school children can’t do it―they don’t vote. Jim and I will continue to explore ways to make our Evening at the Bronx Zoo happen. Meanwhile, our thanks are due to Mark Soberman for heroically filling the breach this evening with his presentation on keeping and breeding Corydoras catfish. On a different subject, you’ll notice that on one of the tables this evening we have some free samples of freeze-dried blackworms from a source selling them online. If you like them (I found them to be quite tasty with a little cocktail sauce), re-ordering information is included with the packets. Thanks!

The G.C.A.S. Proudly extends a most Warm Welcome to

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 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.


Modern Aquarium - Greater City A.S (NY)

Mark’s hobby had been rekindled and it expanded, until eventually he was able to create his June 2010 7

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. In 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. As a result of his acquaintances here, he now serves in the distinguished role of moderator on the highly respected forum, “Planet Catfish,”, 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 and is currently Vice President of the club. Enrolled in 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.

unexpected places. For example: “When I was about seven, we collected cans and saved up money to buy fish, so we always bought them one at a time.” If you want to know what happened when young Marc bought one tiger barb, you will have to read the book! Having read and reviewed over 100 books on the subject of the tropical fish hobby, I have found that Marc offers a uniquely satisfying solution to a problem which aquarists often encounter, and I am going to quote it in its entirety:

you catch a lot more oscars, managuenses, and other South American cichlids than largemouth bass. Your question was about native fish. If you originally caught these fish in a pond, you may think it is O.K. to return them to the wild. But they may have picked up pathogens through contact with fish that you purchased at a pet store. In a perfect world you would have a fishpond in your back yard for fish you no longer want in your aquarium. This prevents any contact with wild fish.”

“If I keep a fish native to my area, would it be illegal or harmful to the fish to release it into the wild? Whether it is legal or not (often it is not), releasing a fish into the wild is unethical and harmful. Our waterways and native fish populations are already in serious danger from aquarium fish that have been introduced into these habitats. Anyone who has gone fishing in Florida knows that

Do I like this book as well as I did the TV show (which has been off the air since September 2006)? Without the drama of watching for Harry to pull the glasses off of Marc’s face, I would have to say no. It does, however, keep you laughing and learning in equal measure!

You need only look at the gill cover to see why this fish was named after a king who turned things to gold. pH of the water you add, you risk an almost immediate pH shock to your fish, and a deadly ammonia spike. I know of no betta species that is not mostly (if not exclusively) carnivorous. The large upturned mouth of Betta midas is a clue that this species is a surface feeder, most likely eating insects that land on the water’s surface. So, I fed my B. midas mostly live, rinsed adult brine shrimp with added liquid vitamins, and live black worms, with occasional feedings of a high protein floating pellet (I used Atison’s Betta Pro). Due to the almond leaf and the Betta Spa, the water was a light brown color. The tank was kept in a dimly lit environment, with full lighting provided only four or five hours a day. My specimens were less than an inch and a half long when I acquired them. Since the scientific paper referenced 66.0 mm specimens (a little over 2.5 inches), I expected to grow them up in this tank, then transfer them into a 20 gallon tank in about year or so when, I supposed, they would have reached breeding size. Only a month or so after having acquired them, I was very surprised to see a few small fry darting about. While there are almost always exceptions, I have had very good luck with leaving the fry of mouthbrooding bettas in the same tank as the parents (and generally poor experiences with removing the fry). I could see no indication that the parents were cannibalizing or harassing the fry (mouthbrooding bettas provide no parental care once the fry are released, and generally just ignore them), so I left the fry in the same tank with the parents.

Modern Aquarium - Greater City A.S. (NY) Modern Aquarium - Greater City A.S (NY)

I always have a culture of microworms going (when I don’t have any fry to feed, my Endler’s Livebearers, Poecilia wingei, appreciate them). When I put some microworms into the tank, even more fry came out to grab a snack. Using a mortar and pestle I pulverized some dry food into dust to make a suitable fry food, which brought even more fry out from hiding. I can now see several generations in that tank, still with no observable predation or aggression (at one point, one of the adult fish sported a torn caudal, but some fin nipping is a frequent occurrence in the spawning ritual of both bubblenesting and mouthbrooding bettas). Mouthbrooders typically have a comparatively small spawn, and considering the size of my specimens, I estimate less than a dozen fry result from each spawning. While Betta midas is still very new to aquarists and not yet common in the aquarium hobby, their small size, relative ease of care, and easy breeding in captivity should make these fish quite popular in years to come.

GRAND CAYMAN’S NORTH SOUND by Stephen Sica hanks to frequent flyer miles, we were sitting in the first class compartment of our plane at Miami International Airport, eating and drinking for free. It was Sunday afternoon, December 6, and we were preparing for departure. Then the pilot’s voice disturbed our fun. A food loading cart had rammed a door, which was now damaged and could not be locked. The plane could not take off without the door being properly secured. The parts warehouse had been contacted, and a search had begun to find a replacement part. There would be a delay. I guess that when you get married on the fiftieth anniversary of the attack on Pearl Harbor, you occasionally have negative thoughts. I wondered if our personal “Day of Infamy” would arrive a day early. Anyway, there was a good chance that the plane would not leave at all. I conjectured aloud to Donna that, today being a Sunday, it would be highly unlikely that anyone would be around to search for the part, retrieve it, and repair the door. Fortunately, I was, as usual, wrong. We landed at sunset. On the half-hour drive to our hotel, the roads were empty. We saw Christmas lights in plazas, resorts, and private homes. We arrived at our “all inclusive” resort in time for dinner. We chose the Cobalt Coast because it was remote, with an


on-premises restaurant, dive shop, and the opportunity to dive the relatively pristine North Sound of Grand Cayman. The resort was small and intimate, with only about two dozen rooms, and modeled after a Jamaican Great House. All rooms were one or two bedroom suites. After breakfast the next morning we returned to our room, where I packed our dive gear for an 8 A.M. departure for the reefs. When on vacation, I believe that it’s good to sleep a bit late. But when diving, the early bird gets to the best dive site first! The boat dock was literally a fifty yard walk straight from the door of our ground floor room. We walked out the door, and to my immediate surprise there was no boat, but plenty of wind and waves. Because of rough seas, the boat had been moved to a protected anchorage about a mile away. Since the sea was too rough to dive the North Sound, the boat headed west to the tourist-fashionable Seven Mile Beach to dive the famous West End. We dove there our first two mornings. The next two mornings we were able to dive the North Sound in a calm sea. Here is a photo essay of just a few of the sights that we saw.

Cichlidically Speaking Your Link to the American Cichlid Association

by Claudia Dickinson

First appearing in the February 2001 issue of the American Cichlid Association’s Buntbarsche Bulletin, my ‘Cichlidically Speaking’ column ran until August of 2005. Its commentary covered current ACA news, as well as relevant cichlid research and conservation efforts. As your ACA Club Delegate, I continue to bring you that column here in the pages of Modern Aquarium. Let us think of it as ‘Volume II,’ or now on its second year with the GCAS, ‘Volume III’?!

ACA Convention 2010 The event that we all look forward to, our annual ACA Convention, is almost here!

July 22―25, 2010 Hosted by the Milwaukee Aquarium Society Olympia Spa and Resort Have you registered yet?!?! Register today at! Be sure to get your room reservations now by calling 800-558-9573. The group code for our special convention rate is MAC10. It’s all about cichlids, and cichlidophiles. We can barely wait to see you there! ACA Convention 2010 Milwaukee The time is here, the time is now for the ACA to take the Olympia Resort and Spa in Milwaukee by storm on July 22 to 25 as we convene for the largest gathering of like-minded cichlidophiles you have ever before witnessed! Rumor has it that this is the year to top all. It must be the famous Milwaukee beer and brats, or is it because word got out that the Bermuda contingent is heading west with a generous supply of Dark and Stormy ingredients?!? Or, maybe it’s those Babes In The Cichlid Hobby who are at it again preparing for their huge silent auction to support the Paul V. Loiselle Conservation Fund, Modern Aquarium - Greater City A.S (NY)

June 2010


the Guy D. Jordan Endowment Fund, and the Stuart M. Grant Cichlid Conservation Fund, as well as that famed Friday night auction of rare and conservation priority species. One never knows what will happen behind those doors, but one can be sure it’s full of fun, and all for a good cause in the name of cichlid conservation and research! The convention speaker line-up has everyone buzzing with celebrated greats such as Ad Konings, Paul Loiselle, Anton Lamboj, Juan Miguel Artigas Azas, Oliver Lucanus, and Lee Newman, plus the late night study groups that offer a plethora of fantastic presenters and topics. If you have yet to meet these cichlid celebrities, your chance is now, as they will be in Milwaukee all weekend and look forward to greeting you, answering questions, and talking fish! Speaking of cichlid greats to meet, the red carpet goes right to Milwaukee with TFH Editor-inChief David Boruchowitz, South American cichlid luminary, Wayne Leibel, Central American cichlid collector and icon, Rusty Wessel, Lake Victoria authority, Chuck Rambo, ACA Chair and Central American collector, Mo Devlin, and the list goes on with so many others. These red carpet stars want to see you there and get to know you, too! Did you say you were looking for cichlids for sale? Milwaukee is the place to be to purchase more rare and exquisite cichlids than you can imagine, or fit into your tanks! To top off the event, witness and take part in the largest cichlid show in the nation, an extraordinary vendor room, entertaining side trips, and a Sunday auction as immense and diverse as your wildest cichlid dreams. Most important of all, enjoy the true warmth and camaraderie of fellow cichlidiots as only our hobby knows. Join the sprint to and, if you have yet to do so, register now! I know I can barely wait to see you there!

News On The Cichlid Scene: Amphilophus rhytisma (López 1983) With a limited distribution from Rio Sixaola in Costa Rica to Rio Calovébora in Panama (Artigas Azas, 2008) and preferring moderate to fast flowing rivers, Amphilophus rhytisma resides in the benthic zone where it feeds on aquatic insects and detritus (http://www.fishbase. org). Less aggressive than other members of the genus, it may even appear shy when housed with more assertive tankmates. The relatively mild manner of A. rhytisma coupled with its medium size of 13.5 cm (5.3 in) make this CARES conservation priority species a perfect candidate for the aquarium.

As sparse as it is in its narrow native range, A. rhytisma is also somewhat challenging to locate in the hobby, although with perseverance a few sources can be found. Hopefully, in the near term we will have more specimens of this exquisite at risk species to distribute amongst fellow hobbyists.

Lake Victoria CARES Conservation Through Education Update Refurbishment of the Kenya Marine and Fisheries Research Institute Aquarium in Kisumu continues to progress! The central air system has just been shipped and hopefully will be in place in the coming weeks in time for a visit to the facility from heads of state. Dr. William Ojwang reports the following: Dear Claudia, I hope all is well with you. We did receive the boxes in good condition with all the items intact. I guess this is a sign that all is well and you may proceed with shipment of the rest. We plan to ultimately have ‘many’ tanks, at least 60 (in the Aquarium, the big outdoor tank, plus the outside racks). That would certainly require a bigger pump as you indicated. The notes were great! Thanks for your insight in the Aquarium setup, outlet numbers, etc. The idea of having a backup air unit is welcome. On the update, we have continued to receive numerous visitors to the facility, people from all walks of life: students from elementary to college levels, heads of government ministries, heads of East African research institutions, universities, and notably we were also visited by honorable members of parliament from the East African Legislative Assembly (EALA). All of our visitors have been full of Modern Aquarium - Greater City A.S (NY)

encouragement and appreciation to our dear donors, you in particular, your friends, and other United States based organizations. We have since moved into the other portion that was hitherto used as storage space. It has been painted and given room for the Aquarium expansion. I talked to Peter in Nairobi on the possibilities of getting a 19 mm (.75 in) thick glass from there as I have visited every shop in our town but in vain. I might have to get it from Nairobi as soon as I confirm its availability. As you may also recognize from our pictures, the outer wall of the facility requires new paint. I hope to embark on that shortly! On another front, we used part of our Aquarium setup during the just concluded Kenyan public service week display. This is an annual event held all over the country, mostly at provincial headquarters by public institutions, to update Kenyans on their respective activities which range from conservation efforts to innovations, etc. The displays are usually judged and positions awarded. As you can see from the pictures and trophies, KMFRI, Kisumu took the first position as the best in delivery of services, thanks to YOU, as we could have not done as well without display of items from our improved Aquarium facility.

Why I’m Not Rich 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. hat aquarist has not thought about turning his or her aquatic hobby into a profitable business? I remember one Greater City member who had a small aquarium store in Queens. As a hobbyist, he was interested in Lake Victorian cichlids, which is a fine speciality. But, instead of concentrating on the “bread and butter” common fish (fancy bettas, common dwarf corys, and common livebearers like guppies, swordtails, etc.), he devoted a disproportionately large amount of his limited tank space to those cichlids. Well, his business went (as we say in the fish hobby) “belly up” and, in hindsight, you can see why. It’s hard to combine work and play, and succeed at both. But what if you could make a profit from a byproduct of your hobby? No, I’m not talking about selling used fish water as plant fertilizer (hmmm now that I think of it, that might not be such a bad idea!). No, I was thinking of algae (you know you have it, come on, admit it).


A researcher from Indiana-based Cereplast holds a plastic disk made from algae. Photo ©Popular Mechanics 1

Popular Mechanics recently reported that an Indiana company intends to make plastic from algae, substituting up to half of the material normally derived from fossil fuels with biomass Modern Aquarium - Greater City A.S Modern Aquarium - Greater City(NY) A.S. (NY)

from the aquatic plants. According to the article, the biggest problem is “getting enough of the green stuff to make it in quantity.” It takes about a pound and a half of dried, pressed algae to make a pound of the algal portion of the plastic. (Oh boy, do I ever have a tank or two to show them!) O.K., here’s the hitch, to make plastic from algae requires “a precise strain of algae from among thousands” that has to be harvested in quantities and dried. Then oil is extracted (that can be used as fuel) and from the left over biomass, plastic can be made. (Today, that left over biomass is, among other things, fed to cattle.) And, just when I’m about to tell my “significant other” that I need a dozen or so 200+ gallon tanks to start an algae factory, some students at the University of Illinois at Urbana-Champaign find a way to grow algae using “electronic waste.”2

A “Bio-Grow” device Photo ©Discovery News

They invented the “Bio-Grow,” a device made from the side panels of an Apple G4 computer tower, with PVC pipes and acrylic panels for support, an Apple iMac CRT monitor for light and heat, and a modified Dell Latitude CPX laptop to control the CRT so that specific light spectrums are used at different times to adjust the temperature within the tank. The tank uses a water pump to aerate the algae, and a faucet to extract the algae. What’s missing in the Bio-Grow is a fish tank with fish! These college kids have just dashed my hope of getting an OK for a bunch of 200 gallon tanks (stocked with fish, naturally), and becoming rich at the same time. Sigh. energy/biofuel/algae-to-plastic
