eading Steve Sica’s scuba-travel adventure stories almost inspires me to learn to scuba dive. Almost. While the idea is appealing, I do have some defensible, rational reasons for not doing so―really! These stories also bring to mind the many and increasingly popular opportunities for viewing aquatic and marine creatures “up close and personal,” in zoos and aquaria, as well as in their natural habitats, to say nothing of the burgeoning number of television shows dedicated to the watery world.

On the one hand this has been a great thing.

New Yorkers are fortunate to have had a long history of prestigious institutions such as the Bronx Zoo and the New York Aquarium. Many other cities now have public aquaria, which are often central to the local economy, giving potential visitors a great reason to come and spend a few days―and a few dollars. Increasingly these institutions are seen not only as great educational resources (be sure and eat your greens, children!), but as quality-of-life assets that will attract business, lend the community some prestige, and encourage their citizens to stay, rather than move elsewhere.

For those of us less willing or able to travel, public television and many of the “cable” channels offer programs of tremendous scope and diversity. On any given day, you’ll likely be able to spend an hour or two learning about some kind of fish, reptile, mammal, or even more primitive life forms, including information about their history, diet, social organization, ecology, population statistics, etc., all presented in an entertaining and compelling way. The available choices and their quality are staggering!

As much as I appreciate it though, there’s something vaguely unsettling about it all. Perhaps it’s because this apotheosis of nature film-making and aquarium building seems to be taking place against a backdrop of desperation as regards the real-world situation of most of these creatures.

Yes, it’s all beautiful―even breathtaking―but much needs to be done to assure that such scenes will survive in the wild (will there even continue to be a “wild?”) and not just in our electronic

images of them. Habitat destruction continues apace, fueled by continued human population growth, about which conversation seems to have ceased.

So the paradox seems to be that more people than ever are conscious of the imperative for conservation, but “more people” are making that conservation more difficult by the day. I’m confident that our speaker this month, Jim Breheny of the Bronx Zoo (and GCAS member) will have some insights for us, which I look forward to hearing. For other conservation insights, be sure and see Claudia Dickinson’s “Cichlidically Speaking” in this issue. Claudia has been and remains a force behind the CARES program, a ‘fishkeeper-centric’ conservation program that deserves our support.

Besides the entries this month from Claudia and Steve, we have a “Wet Leaves” from Sue Priest that’s very relevant to this evening’s speaker.

Sue also presents us with a new “Anonymous Fishkeeper” to unmask. Al Priest profiles Betta pulchra, the rarely encountered but aptly named ‘beautiful’ betta, while Bill Amely gives us breeding tips on a hobby favorite, the zebra danio. “Through the Lens,” “The Undergravel Reporter,” and “Fin Fun” round out the issue.

My thanks, as always, to our wonderful authors.

President’s Message

by Dan Radebaugh

arly last month I took advantage of an opportunity to attend the NEC’s (Northeast Council of Aquarium Society’s) annual Presidents meeting in Farmington, Connecticut.

The event was well attended. The speaker was John Todaro, from the Brooklyn club, who did a presentation based on his series of articles, “Secrets to Society Success,” that has been running in Aquarium Fish International.

John has experience in marketing and advertising, and his ideas are sound. I don’t propose to recap them all here, but his presentation, coupled with another I attended last week―this one presented by well-known media maven Jeff Jarvis, and based on his new book, What Would Google Do?, stimulated me to reflect on the state of the fishkeeping hobby, and to wonder how organizations like Greater City fit into the changing landscape of the society at large.

One of the complaints I hear from many people (inside and outside the hobby) is that young people today are only interested in computer games, so they’re not going to keep fish, they’re not going to go to meetings, and we’re all going to die. Well, we are all going to die (If you discover a loophole, do let me know!), but I don’t think it’ll be from young people playing computer games (though there was that movie, War Games, a few years back, so maybe I’m wrong).

What there can be little dispute about however, is that there is now a lot of competition for peoples’ attention, and it comes at us from more sources than ever. When I was growing up, there was print (newspapers, magazines, etc.), radio, and television.

That was about it, unless you count billboards (and we used to do that―literally―on long, preInterstate car trips). Now, with satellite radio, about a gazillion TV channels, and the World Wide Web, our attention is much more fragmented.

This in turn means that, on the positive side, we have loads more choices than we used to about nearly everything. Need a left-handed cataract surgeon who speaks Ladino and is on your insurance plan? Look on the Web! On the negative side, there are so many choices out there that even good ones can easily be overlooked.

Things change. I began keeping fish a good number of years ago (Eisenhower was President).

Even then, traffic patterns changed, neighborhoods and towns rose and fell, and once-successful businesses failed, to be replaced by others. Much has changed in our hobby. The equipment we use is better, the foods we buy are better, and we have a more solid scientific basis for a lot of our fishkeeping decisions. One of the things that has remained true is that people like to gather and exchange thoughts and experiences with others who share their interests. If you look around the room tonight, you will see that this is so.

Greater City has been helping us keep up with changes in fishkeeping knowledge for many years.

I’ve only been a member for about five years, but during that time our membership, while of course changing somewhat from year to year, has remained strong and stable. I take this to mean that we are providing something of value to our members (ourselves, after all). We must of course continue to do so. Our other challenge is to be sure that we’re visible. Potential new members need to know that we exist, and to be able to find us.

I recall that in Joe Ferdenzi’s retrospective of his tenure at GCAS (published last year in Modern Aquarium), he mentioned learning of GCAS from a flyer posted in a fish shop. There’s an example of a small effort that certainly paid dividends many times over. More personally, when I had reimmersed myself in the hobby a few years back, I mentioned to Marsha, “You know, there are chess clubs and camera clubs. I wonder if there are aquarium clubs.” So we looked online, and found the GCAS Web site. The moral is that there’s no one and only way to do it, but we do need to help people find us.

Speaking of our Web site, if you’ve looked lately, you’ll have noticed that it’s “under construction.” The old hosting service has shut down, and our Webmaster, Al Priest, has moved us to another. I say “moved” rather casually. In fact Al’s having to rebuild it from scratch. You can find us at http://www.greatercity.org. Greatercity.com will also work. Right now it’s just the bare bones, but we have some ideas for improvement which you’ll hear more about in the future. Stay tuned!

Handsome is as Handsome does The Handsome (or Beautiful) Betta, Betta pulchra

by ALEXANDER A PRIEST here are many species in the genus Betta (with new species still being discovered), and some of them are very attractive. One member of this genus has the scientific name of Betta pulchra (pulchra is Latin for “handsome” or “beautiful”) and at least the males of this species certainly live up to their Latin name. I highly recommend this species to anyone in the aquarium hobby. It is not endangered, but it will almost never show up in your local fish store. If it does show up in your local store, grab it. If it shows up at an aquarium society auction, grab it. If it shows up at a tropical fish auction site, such as AquaBid.com, grab it—I’ll tell you why.

Betta pulchra is a somewhat newly described fish, having first been described in 19961. It is native to blackwater habitats in Pontain, which is in the southern province of Johor, on the southwestern side of the Malaysian peninsula, Betta pulchra quite close to Singapore.

Betta pulchra is a paternal mouthbrooder, and can be bred in captivity. The spawning ritual of Betta pulchra is similar to that of other mouthbrooding bettas. Generally, it’s the female that initiates the spawning. First, the pair entwine their bodies, with the male gently squeezing the female. When eggs are squeezed out of the female, they land on the slightly arched anal fin of the male. The female picks the eggs up in her mouth, along with some of the male’s milt. The eggs are mixed with the milt in the female’s mouth and become fertilized. Then, the female spits the now-fertilized eggs out in front of the male, who catches them and holds them in his mouth. Finally, the male incubates the eggs in his mouth until they hatch.

The incubation period for Betta pulchra ranges from 12 to 18 days, with 14 days being the norm. The incubation time can vary with water temperature (the warmer the water, the shorter the incubation period). Generally, once the fry are hatched, they are ignored by the parents, who

T

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

provide no parental care (but, unless starved, the parents also exhibit no predation towards the fry).

A spawning tank should contain no more than one pair of Betta pulchra, and have multiple caves.

It is my practice to have a sponge filter in all my spawning tanks, because within two weeks or so of operating in a tank with fish, the sponge starts to become a colonizing site for infusoria and paramecia that can serve as first foods for fry.

While he is incubating the eggs, the male will hide in a cave. It is usually not necessary to remove the female parent while the male is brooding, but I prefer to do so if—and only if—I can remove her quickly and without unduly disturbing the male.

Once released by the male, the fry should be fed newly hatched brine shrimp, microworms, and daphnia.

Most of the species in the genus Betta have been grouped by hobbyists and some Photo by Al Priest conservationists into “complexes.”

These complexes do not necessarily represent the degree of genetic relatedness among the members of a given complex, but rather seem to be based more on similarities in physical appearance. Betta pulchra is a member of the Betta pugnax complex, but it is never found together with Betta pugnax in the wild. For that reason, and because of various physical similarities, Betta pulchra was originally suspected of being a blackwater variation of Betta pugnax. However, Betta pulchra and Betta pugnax have each been found to breed true, regardless of the water quality in which they were raised. (In other words, when Betta pugnax was kept in the same blackwater environment that Betta pulchra is native to, the resulting fry resembled Betta pugnax, not Betta pulchra.)2 Betta pulchra differs in appearance from Betta pugnax by having a stouter body and a caudal fin that tapers to a sharper and narrower point. A female pulchra is slightly wider, is less colorful, and has shorter fins. Males may fight among themselves, whereas multiple females can be kept together.

LIONFISH INVADE CAYMAN ISLANDS

by Stephen Sica

O

n May 1, 2009 at approximately 9:30 AM Central time, a divemaster named Sunshine discovered a juvenile lionfish, Pterois volitans, about two inches in length plus fins and spines, hovering next to a concave piece of dead coral on a dive site called Marilyn’s Cut, just offshore of Little Cayman Island. The fish was living on a coral reef in about thirty feet of water, atop the six thousand feet deep Cayman Trench. I was swimming just behind Sunny when she found the fish and signaled her discovery to me. I did not see what she was so excited about until the fish swam under the coral that appeared to be either the fish’s home or hiding place.

The coral was about fourteen inches long, and probably weighed about six or seven pounds.

Since I did not immediately see the elusive fish, I did not have an opportunity to photograph it.

Sunny used a thin metal rod about eighteen inches long to work the coral and the fish into a large, clear, heavy duty plastic bag, and then she used the rod to push the coral out of the bag, which she immediately took to the surface while Donna and I continued our dive.

the thirty-fifth lionfish captured in the Cayman Islands (the group consists of only three islands).

Sunny stated that all fish are captured alive and studied (including DNA testing) by the local marine biology laboratory. Afterwards, most of the fish are euthanized and dissected. Since lionfish have very few predators, and propagate easily in the wild, the general policy of the local scientific community has been to destroy them, though a small number of fish are tagged and released for follow-up study. Sunny claimed that one dissected full-sized Cayman lionfish had more than twenty-five grunt fry in its stomach.

The fish that Sunny captured was placed in a plastic pail where Donna and I inspected it. I never thought to photograph it in the pail until later, when I was formulating this brief article in my mind. Of course by then it was too late! Anyway, I did take a few photos of Sunny capturing the fish. Some of these photos accompany this article. If you look carefully, you can see the fish in the plastic bag.

Later, on the boat, Sunny said that the first Cayman Islands’ lionfish was discovered and caught in February of 2008 off Little Cayman. No more were found until December of that same year.

The fish that Sunny captured was approximately Modern Aquarium - Greater City A.S (NY)

by William Amely

ne of the easiest species of fish I have ever bred is the zebra danio (Danio rerio, formerly Brachydanio rerio).

Even their fry are very hardy and easy to rear.

The danios’ torpedo shaped bodies allow these small fish to swim about very rapidly. It is always an entertaining sight to see a group of six or more of these energetic fish moving rapidly back and forth in the aquarium, seemingly playing a game of “tag” with each other.

While the information I will provide below focuses on the zebra danio, this technique would also work well with the leopard danio and pearl danio, as well as the black tetra.

A two-and-a-half or five-and-a-half gallon aquarium will do fine as a breeding tank.

Zebra danios are egg-scatterers, so I recommend lining the bottom of the aquarium with glass marbles. The eggs can then fall between the marbles, preventing the adults from getting to them and eating them.

Males are very slender in appearance, while the females are very round in their belly area. In the evening, place at least one ripe (really round) female and two males into the breeding tank.

Overnight, they will spawn, and dozens of eggs will be laid scattered about. At normal room temperature, the eggs will hatch in about 24 to 36 hours. The very small fry will be surprisingly hardy, and can be fed fine powdered or flake food if there is no live or frozen food available. They grow rapidly and can tolerate a wide range of water conditions.

Temperatures between 72 and 76 degrees Fahrenheit are fine. Water changes do not hurt the fry―to the contrary, they will thrive.

I normally change about 50% of the water once a week.

Zebra danios are fun to watch, and their colors can be striking when they are in peak form. They are a great addition to a community aquarium, where they generally swim in the upper levels of the water column.

Give them a try. You won’t be disappointed.

Happy Fish Keeping.

ACA Founding Fellow Dr. Paul V. Loiselle and Ptychochromis loisellei Named after ACA Founding Fellow, Dr. Paul V. Loiselle, Ptychochromis loisellei was described by Melanie Stiassny and John Sparks of the American Museum of Natural History in 2006 in honor of Loiselle’s vast achievements and the contributions that he has made in preserving Madagascar’s most endangered vertebrates. Pt. loisellei was discovered

by Loiselle in the year 2000 in the Mahanara du Modern Aquarium - Greater City A.S (NY)

Nord River of northeastern Madagascar. This is the second cichlid to bear Loiselle’s name, the first being Parachromis loisellei of Central America.

A renowned and highly respected ichthyologist and champion of conservation, not only within the ranks of the ACA, but reaching worldwide, Loiselle travels on an annual basis to Madagascar under the Wildlife Conservation Society. His invaluable field research has played a major role in establishing conservation priorities for aquatic habitats in Madagascar as well

Very Fishy Medicine 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. t one time, swallowing live fish was popular among college students. While I would have thought people are smarter today than they were then, it seems that what is no longer being done for “fun” is still being done in the name of medicine (folk medicine, that is).

For the last 162 years, the Goud family in India’s southern city of Hyderabad has been offering a cure for respiratory illnesses, such as asthma. The treatment consists of patients swallowing a live two-inch-long Murrel fish that had a secret herbal mixture stuffed inside its mouth.

A satisfied patient?

There are a number of fish, including species kept by some aquarium hobbyists, that are known to change sex, in response to the lack of a member of the opposite sex within a group. However, scientists are discovering that pollution is also a major factor in sex changes of fish.

British scientists have found male fish are taking on female characteristics because of hormones and pollutants discharged into rivers and estuaries. They believe that high levels of estrogen compounds found in the water are due to the widespread use of the contraceptive pill. Sex changes in fish are a concern because, if males take on female characteristics, it will interfere with reproduction and could jeopardize the survival of a species. Last year, the British Environment Agency warned that a third of male fish in English rivers could be changing sex due to female hormones in the water.2 Australian scientists intend to use a new $6 million laboratory to establish whether traces of drugs in the waterways are changing the gender of fish. Research scientist Dr. Anu Kumar said she wanted to see what would happen when native fish were exposed to effluent from waste water treatment plants which contains residues of drugs and personal care products that interfere with hormones. Her laboratory is equipped with the tools she needs to find out whether males start turning into females.3

This live fish travels through the throat, wagging its tail and fins. In the process it negotiates through any phlegm and congestion, and is claimed to provide a 100% cure. Three extra doses of the medicine must be consumed once every 15 days thereafter, with patients following a specified diet.

To effect a permanent cure, treatment must be repeated for three consecutive years.1

How often have you asked “how long will that fish live in my aquarium?” Well, the oldest known fish at a public aquarium is called “Granddad.”

Granddad came to Chicago’s John G. Shedd Aquarium in 1933. As the world’s oldest living aquarium fish, his age is possibly 80 plus.4
