t’s summertime! Not that anyone who was here at our meeting last month would doubt it. During this time of year, many aquarists’ thoughts turn to subjects like moving their fish outdoors, and cultivating live foods. Coincidentally enough, this issue contains articles on both of those topics! Steve Sica tells us about his experience setting up an outdoor fish tank, and Joe Ferdenzi gives us an overview of how to raise a never-ending supply of daphnia, one of the best live foods available for small fish. Steve also checks in with his “Fish Bytes” column, a review of other fish society journals from around the country, and even outside the country! Al Priest contributes a photo spread from last month’s meeting, dedicated to recipients of FAAS awards for 2009. Al reminded me to mention that Greater City had three married couples who won awards this time! Wow! For all you authors out there, remember that winning an award from the FAAS or the NEC gives you bonus points in Greater City’s own Author Awards Program. Al’s photos also include last month’s Bowl Show winners, and he also gives us a short, beautifully photographed article on the use of caves for spawning mouthbrooding bettas. Ever prolific, Al also chips in with the Fin Fun puzzle that ends the issue. As I write this introduction to our issue, I notice (all by myself) that every author in this current issue, including the Undergravel Reporter, is a current FAAS award winner. This highlights the quality of contributions we have become accustomed to here at Greater City. Once again, I congratulate all of our talented writers!
We need more articles! We can’t be complacent! 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 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!

MY BACKYARD AQUARIUM Story and Photos by Stephen Sica
H
aving attended many monthly meetings of the Greater City Aquarium Society, and as its exchange editor, having read countless club publications and magazines on the fine merits of outdoor fish ponds, barrels and tubs, I decided that, as a result of having some free time, 2010 would offer me an opportunity to give it a try. When we purchased our house many years ago, it had a small backyard pond that I never used. After a rain I would often find frogs and other creatures in it, but the next day they would all disappear. After a couple of years, I deemed that it was not practical, and filled it in. I did not wish to invest much money in this new venture, so in order to support my project I went down to my basement to rummage through any unused or broken equipment that might be there collecting dust. I found the six gallon acrylic tank from my broken Marineland Eclipse Aquarium. The next day I dragged a heavy concrete pedestal from my garage and placed it up against the garage’s south wall. The pedestal was one of two that were formerly used to display carved dragons that had adorned the backyard. We had purchased our home from a Chinese family, who had decorated their property in a traditional Chinese motif. Coincidentally, about fifteen years ago we donated the other decorations to the Queens Botanical Garden. Some of them were on display in the wedding garden area for a number of years.
Modern Aquarium - Greater City A.S (NY)
I placed the six gallon tank on the pedestal, and half-filled it with aged water from an operating tank. I topped it off with regular water, threw in a small clump of Java moss, and covered the top with a piece of black fiberglass screening. Last year, I had repaired the screen on my front storm door, and had fortunately kept the leftover screening. The very small holes were perfect for keeping leaves and acorns from my neighbor’s tree from falling into the tank. A few days later, I purchased six White Cloud Mountain minnows (Tanichthys albonubes) from a local pet store, and added them to the setup. I figured these hardy fish would be too small to attract the attention of the local raccoons. Besides, since it was mid-May, with its cold nights, these fish should be quite comfortable. I lost one fish about ten days later, but the remaining five appeared robust.
A week later I attended the June GCAS meeting, and successfully bid on a bag full of White Clouds ranging in size from adults to fry. I also won a bag of duckweed (Lemna minor) that I really did not want, but that no one else was bidding for. When we arrived home, Donna asked where I would put the fish. I didn’t have an answer, so I put them in a small holding tank for the night. The next morning I went down to the basement to scrounge around some more. I discovered my old SeaClear twenty gallon acrylic “show” aquarium. Of course its face was scratched, but the non-viewing sides were perfect! It is described as a “show style” because its width is only ten inches with a thirty inch length. I decided to replace the six gallon with this twenty.

I hauled out the second pedestal and placed it end to end with the first one, then laid a short plank of pine across both pedestals, and centered the twenty gallon on the wood. I trimmed the screening for a better fit, and in my garage located a twofoot section of one-by-four inch pine, that I laid across the top to keep the screen in place. Then I transferred the water, fish and moss from the six gallon, and added the new fish, along with another clump of moss, and additional water from my garden hose. I have read that the experts believe that this filling method is contra-indicated due to alleged toxic chemicals in the hose composition that are harmful to the fish. My opinion is that if I could take an occasional drink through a garden hose in my younger days, it’s good enough for the fish today. It’s never bothered me―so far! I left two inches of clearance in case a heavy rain should flood and overflow the system. Finally, I spread almost all of the duckweed on the surface of the water. About one week later I changed a few gallons of water, and the Java moss floated to the surface, where it remains in spite of all my efforts to poke it back down to the bottom. I think that the duckweed may be keeping it afloat.
8
When a June heat wave arrived, the water and aquarium walls developed a coating of algae, so I changed about one-third of the water, but with no effect. Then I put a siphon in the tank while concurrently refilling using the garden hose. It dawned upon me, albeit rather late, that the green water look was predominantly the result of algae on the aquarium walls, so I scraped the front clean. Behold, I saw my fish―and I think that they saw me! I completed this article in early July. On the thirteenth of the month, Donna and I will depart town for almost two weeks, so the fish are going to be on their own. Right now, I wonder what we’ll find when we return home. Ironically, by the time this is published, I’ll know!

Live Foods: My Perpetual Daphnia Tank by Joseph Ferdenzi
S
ome of the best discoveries are made by accident. So it was with what I call my perpetual daphnia tank. What makes it a wonderful discovery? That will become clearer after I give you a little background on daphnia and daphnia raising. Daphnia are minute freshwater invertebrates, and they make an excellent live food for aquarium fish. Here is the problem: pet shops don’t sell them anymore. Once upon a time daphnia were the staple live food used in the aquarium hobby. Just peruse any book or magazine devoted to aquarium fish from the 1930s, ’40s, or 50s, and you will see copious references about daphnia as fish food, where to collect them, and how to culture them. When I was just starting out in the hobby (mid 1960s), you could walk into virtually any pet shop, especially those featuring tropical fish, and find daphnia for sale. I don’t know exactly when shops stopped carrying them, but they gradually were phased out (at least in New York City) sometime in the ’80s. Real old-timers tell of collecting daphnia in the wild from stagnant ponds that were free of predators (like fish). Alas, land development and mosquito eradication programs have done away with once cherished collecting sites. With no commercial or wild sources available, what was a hobbyist to do? The answer seems simple―grow your own! Ah, but there is a rub to that as well. You see, no live food is all that easy to culture. There are ways to do it, but all the methods I had observed first hand were somewhat cumbersome. Allow me to illustrate. One of the great veterans of the hobby, Bill Jacobs (New Jersey), used to culture his daphnia indoors with a system of 5-gallon plastic pails. Bill would set out a row of about three to four pails on the floor of his basement fishroom, in the path of sunlight streaming in through one of the windows. Each pail would then be filled about three-quarters with water that was allowed to age for a few days. Into this aged water would then be added the following: a few scraps of iceberg lettuce, a handful of red ramshorn snails, and then some daphnia. The idea was that the snails would eat the lettuce, thereby producing the “green water” that the daphnia would then feed upon. By staggering the inoculation of the buckets, Bill could produce a steady supply of daphnia. When a bucket went bad (foul water), he would start afresh.
Modern Aquarium - Greater City A.S (NY)
Another well-known hobbyist and live food expert, Harry Faustmann (Long Island), uses a different method. He sets up a small tank that produces green water, primarily by using intense lighting after he has inoculated the tank with some green water starter. When the tank is full of green water, he then feeds it to his daphnia culture. In essence, he has a rotating system of tanks: one produces green water, and the other houses the daphnia. While the daphnia are eating the green water in one tank, another tank is producing the next batch of green water. The only problem with both of these methods is that you have to be vigilant; if you are not producing enough green water, the daphnia will eventually die out. Suffice it to say that indoor daphnia propagation is enough of a hassle that most aquarists who want daphnia propagate them outdoors. There, a container of water inoculated with grass clippings or rabbit food pellets, set out where it gets some sunlight, will produce daphnia throughout most of the year. When the weather turns cold the adult daphnia die, but their egg cysts survive until the return of spring. It is much easier to culture daphnia outdoors; the only drawbacks being that you have no daphnia in winter, and you have to figure out a way to keep mosquitoes from reproducing in your “daphnia pond.” I do this by using window screening over the container.
A few years back, I acquired an old-fashioned stainless steel tank at the annual Greater City A.S. Silent Auction that was probably the most diminutive that I have ever seen. It measures 10”L X 6.5”W X 8”H, and probably holds about one-and-a-half gallons. I decided it would be suitable for growing some pygmy chain sword plants and a small colony of August 2010 11
non-fancy guppies. I outfitted the bottom with about an inch-and-a-half layer of number three size natural quartz gravel (which has a light gray cast) and an incandescent stainless steel reflector that fit the top. However, I did not want to use an incandescent bulb, because it a) is not energy efficient, b) produces too much heat, and c) would not give off as much light as a compact fluorescent bulb. I reasoned that the sword plants would need abundant light to grow well, so I chose a bulb that produced the equivalent light of a 40-watt incandescent bulb. I also reasoned that the algae would be kept in check by the pond snails I would add, as well as the ever-nibbling guppies, not to mention the hoped-for lush growth of sword plants. Well, reason can only take you so far. The setup worked fine for awhile. The plants sent out runners, the snails did their thing, and the guppies were fine. But after some weeks, the water began to turn pea-soup green. Granted the tank had no filtration, but obviously the intense lighting was largely to blame for the green water. OK, I thought to myself, the green water is not killing the guppies, and if I keep up with my water changes and don’t overfeed the fish, eventually the sword plants will win the battle with the algae, and all will be well. Nice theory, but no such results; the water stayed so green that I could hardly see the fish. This struggle went on for months without any success on my part. Next move: remove the fish, and for now (I said) I’ll just get some of my outdoor daphnia, put them in the green water, and after the water is clear I’ll figure out what kind of lighting will give me the correct balance to enable the sword plants to thrive, but not produce green water. As for the daphnia, I’ll have enough for one feeding of the fish, and that will be that. Sure enough, the scoopful of daphnia did their work. Within a week the water was crystal clear. OK, next I’ll figure out what lighting to use, and then my fish will get a daphnia treat. Next never came. You know how it is―you get busy, you’ll do it next week. As we say in Italy, tomorrow never comes. But as time dragged on, I began to think that something remarkable was happening. I observed that the daphnia were not dying off, but rather were increasing in number. They were multiplying despite the fact that the water was not green, and that I was not feeding them anything! Hmmm, I thought to myself, how long can this go on? Over a year later, it is still going on. The tank has the same gravel, the same sword plants, the snails, the compact fluorescent bulb (warm white), and no filtration. The water temperature fluctuates between 73° and 75°F, and the pH is about 7.5 (slightly alkaline). Despite the snails, algae does grow on the sides of the tank and over the plants, so I recently added a small (two inches) Ancistrus catfish (that’s a suckermouth variety) to help with the algae chores (I also feed it tablet food several times a week). The 12
Colony of albino Ancistrus catfish (in a larger tank).
daphnia continue to thrive, and I do nothing except an occasional 10% water change (maybe once a month), and I top it off if there’s significant evaporation. My perpetual daphnia tank produces enough daphnia to feed my smaller fish this treat about once every two weeks (I consider 35 of my 45 aquariums as having smaller fish, albeit there are small populations in each tank). This may not be a lot, but the benefit is that there is no real effort involved. Given my busy life, I’ll take that trade-off any time! My explanation for this phenomenon is simple (remember that I’m not a professional scientist―I have a doctorate, but it’s in law): the light that produced the green water is still doing so, but because it is in equilibrium with the daphnia population, the water does not get a chance to turn green. The algae cells that produce the green color are eaten as fast as they reproduce. Does anyone have a better explanation? If so, I’d like to hear it. But regardless of the explanation, anyone who wants to have a nofuss method of culturing daphnia indoors can try to replicate these conditions. Maybe it would work in an even bigger tank―say a ten-gallon, with even more satisfactory results (more daphnia for more feedings). Anyway, good luck to anyone who cares to try this method; I’d enjoy hearing about your results. Or better yet, reading about them in the pages of Modern Aquarium!

or, Spawning Mouthbrooding Bettas by ALEXANDER A PRIEST - photos by the author he genus Betta consists of species that reproduce in one of two ways: by building bubblenests, or by mouthbrooding. Bubblenesting bettas belong to one of three “complexes” (there are currently eleven): the Splendens Complex, the Coccina Complex, or the Bellica Complex. All other Betta species are mouthbrooders (although some members of the Coccina Complex have also been reported to spawn by mouthbrooding). All mouthbrooding Betta species are paternal mouthbrooders, meaning the male holds fertilized
T
First, I use no substrate. Mouthbrooding bettas spawn by the male encircling the female, thereby expelling her eggs. The female puts the eggs in her mouth and nibbles at the male’s vent to obtain his milt, thereby fertilizing the eggs in her mouth. Then she “tosses” the eggs, one by one, to the male, who catches and keeps them in his mouth. This process is made more difficult if an egg falls among gravel. Plants are hardy low-light species (Java moss, Anubias sp., etc.), anchored to driftwood or rocks.
Suitable “caves” come in all sizes, shapes and colors eggs in his mouth until they hatch. Most mouthbrooding bettas require soft acid water, and low-light tanks. The only exception I know of is Betta simplex which, being native to limestone pools, prefers hard alkaline water. So, except for B. simplex, here is how I create favorable spawning environments for mouthbrooding bettas. Keep in mind that for many species of Betta mouthbrooders, unless the pair are totally compatible, there is nothing the aquarist can do to induce spawning. Modern Aquarium - Greater City A.S. (NY) Modern Aquarium - Greater City A.S (NY)
Next, I use dual filtration: a power filter of some kind, and a sponge filter. I cover the intake of the power filter with filter material to avoid “sucking up” fry. The sponge filter provides even the smallest fry with microorganisms to graze upon. Most Betta species adapt to a wide range of water parameters, but I find duplicating their native water assists spawning. Since most Betta species (except for Betta simplex) come from soft, acid water, I add blackwater extract or Atison’s Betta

Now for the big “secret”: CAVES! Caves provide a sense of security (stressed fish don’t spawn), give brooding males a quiet place to stay, and provide shelter to harassed fish. For Betta mouthbrooders, always have more caves than fish.

I
was trying to make a quick exit from Greater City’s March meeting when Claudia called out my name. Foolishly, I stopped and turned around, and she pushed at me a handful of publications from various aquarium societies. Thank goodness they are mailed to her rather than to me. Back home, it occurred to me that now I have an excuse for some of my dated ramblings―it’s Claudia’s fault! Well, it sure feels good to be off the hook (for now). Some online publications that are beginning to be e-mailed to me are the Pioneer Valley Aquarium Society’s The Underwater News, the Delaware County Aquarium Society’s Fin Fax, and the Cleveland Aquarium Society’s The Wet Thumb. Pioneer Valley is located in Springfield, Massachusetts; Delaware County is in Springfield, Pennsylvania; and Cleveland is in Cleveland, (Ohio, of course). The Cleveland society was established in 1923. Its March/April issue reprinted an article that was originally published in its April 1968 issue. They also publish a member’s tank profile that reminded me of Sue Priest’s GCAS “Fishkeepers Anonymous.” I found the tank profile both interesting and enjoyable reading. I realize that some of our members may also be members of the Long Island Aquarium Society, but “Angelfish Surprises” in February’s Paradise Press caught my eye. A female and two male angelfish lived happily in a twenty-nine gallon tank. The males took turns caring for fry; the “stepfather” initially tended newborn fry and the biological father tended young free-swimming fry. Both returned wandering fry to the nest. They may only be fish, but I found the story heartwarming! Here is some interesting information from Kitchener-Waterloo’s Fins & Tales. The Canadian

government wants to treat ornamental fish similar to the manner in which it treats exotic birds, reptiles, and mammals. Shipments will be subject to a good deal of paperwork and inspection. Zenin Skormorowski’s April “Exchange Editor’s Report” mentions Sue Priest’s book review of Catfishes by Lee Finley, and Dan Radebaugh’s chocolate cichlid article, both of which appeared in Modern Aquarium’s March issue. After attentively listening to Mark Soberman’s “Keeping and Breeding Corydoras,” I came across Eric Bodrock’s spawning article, “Corydoras sp. CW 21,” in the July 2009 Finformation. From Mark’s talk I now know that “CW” indicates a yet to be described species; this one happens to resemble C. axelrodi. The author reported success in breeding this catfish. The January issue of the Reflector contains a very brief article, “The Miracle of Subwassertang and Taiwan Moss,” by Ray Spahn. He recounts that at a club meeting he picked up the above two plants that were new to him. He added them to his thirty gallon aquarium that always had some algae growing on the glass and on the leaves of the older plants. After six weeks the glass was clear, and after eight weeks all plants were algae-free and growing better than ever before. The Youngstown Aquarist’s January/February 2010 issue reprinted from our August 2009 issue of Modern Aquarium Al Priest’s “The Fish from Bung Borapet Swamp, Rasbora borapetensis - the Brilliant Rasbora.” The Missouri Aquarium Society’s March/ April 2010 The Darter reprinted an article coauthored by Joe Ferdenzi. “The Natural History and Aquarium Husbandry of Pachypanchax sakaramyi

(Holly, 1928), The Lost Killifish of Madagascar” was originally published in the June 2005 Modern Aquarium. It was kind of Aquatica’s Exchange Editor, Stu Hershkowitz, to mention articles by both Sue Priest (“My First Favorites”) and Dan Radebaugh (“A Visit to Cold Spring Harbor Fish Hatchery”) in his January/February column. Also, Izzy Zwerin profiles two plants in his “The Practical Plant” column: propagating Anubias congensis and Cryptocoryne balansea. He recommends Caribe Sea’s “eco-Complete” as a substrate for both plants. Alesia Visconti authored “Tips to Prevent Fish Loss” in January’s North Jersey Aquarium Society’s Reporter. She believes that the primary reason people give up our hobby is fish loss, and offers these suggestions: before putting your hands into the aquarium, remove all potential pollutants, such as lotion, cologne, and nail polish remover, from your hands and arms; don’t let your (long) hair touch the water if it has gel, mousse, or spray. I wish that I had this problem. I guess it mostly applies to females and former hippies. Keep aquatic gloves available for emergencies. Make sure that your frozen fish food did not thaw prior to purchase. This may be difficult to determine if a dealer is unscrupulous. Use the drip method, or something similar, to acclimate new fish; and lastly, (I never considered that some shops keep fish with plants); fish diseases can be carried in on plants―including the cyst and/or larval stage of ick. Bathe new plants for fifteen minutes in a water and a clarified lime mixture; rinse thoroughly afterward. But be careful, or you may also kill your plants. Joe Graffagnino authored “Thorichthys malculipinnis” for North Jersey’s May Reporter. This small Central American cichlid is “beautiful, friendly, and would be a welcome addition to any aquarium.” Here’s a credit that I probably missed. The October 2009 Reporter reprinted Joseph Ferdenzi’s “DOUBLE ROYALTY: LaCorte’s Emperor Tetra.” Did you know that there are various species of emperor tetras, differentiated by color variations? Me too, because I read both the original and the reprinted article! In its October Exchange Report, the Reporter mentioned several articles from the July, August, and September 2009 issues of Modern Aquarium: my own experience with lionfish in the Cayman Islands, William Amely’s “Breeding the Zebra

Danio,” Joe Ferdenzi’s “Voyage to the Bermuda Fry-Angle,” Michael Vulis’ “Breeding Rhinogobius duospilus,” a William Amely article on Betta splendens, Donna’s “Bermuda Blues” experience, Jules Birnbaum’s “A Small Fish for a Small Room,” Dan Radebaugh’s “On the Road, A Visit to Mote Marine Aquarium;” and finally the lovely Marsha Radebaugh’s “The Fishkeeper’s Wife’s Top Ten.” Still another article that caught my eye was published in the September/October 2009 issue of the Brooklyn Aquarium Society’s Aquatica. “Rummynose Tetras, A Fish That Can Drive You To Drink,” by John Todaro, describes his experiences with a new fish. His article begins “This is a very sensitive fish.” Personally, I feel that every fish is sensitive! For several years I have kept a school of about twenty-five in a thirty-six gallon aquarium along with cardinal, and currently neon tetras, after the cardinals expended their life span. The tank has no catfish. I believe that John is quite accurate when he states that the fish need to be carefully acclimated to a cycled tank. Although John eventually lost all but three of the twenty-four fish that he put in his tank, I have not lost a fish in years other than to old age. I think that the secret might be to have many plants in a well-established tank. I read an endorsement for an ingredient or food referred to as “natural astaxanthin.” It may be a frozen fish food or perhaps an additive that is supposed to help condition breeder fish without having to feed them live food. I know nothing of this substance, including the accuracy of this claim. But I thought I’d mention it as a potential research project for someone.
This Rock hind, a member of the Grouper family, does its best to blend into the background, but Donna knows she’ll have an easy time making a fish with the measles talk!
