Ohio University scientists André Fernandez and Molly Morris studied three populations of female swordtails, tiny Our guest speaker for February will be Bill Gibbons, talking about what the hobby has meant to him and his experiences. researchers placed a female swordtail in the middle of a tank with two partitions. They positioned a male with the faux pattern from which melanomas freshwater fish native to North form on one side, and a male Aug. 18, 2008 and Central America, and found without the pattern on the www.ohio.edu/research/ that two of them preferred other. After releasing the female c o m m u n i c a t i o n s / males whose tails were painted from an opaque tube into the fish_cancer_gene.cfm ATHENS, Ohio — Though skin cancer is deadly to male fish, it also has one perk: The black melanoma splotches arise from attractive natural markings that lure female mates. A new study published in the Proceedings of the National Academy of Sciences this week shows that the melanoma gene can be conserved in swordtail fish because of its beneficial role to resemble the skin cancer spots. The researchers also examined specimens of swordtail fish with real melanomas, which confirmed that the cancer gene is switched on only in the tissue with the dark pigment. The study marks the first time scientists have found a cancer gene linked to a pigment pattern that functions to increase mating success in animals. In the current study, the tank’s center chamber, the scientists observed how much time she spent looking at each male during an eight-minute period. The project builds on previous studies in the Morris lab, which used the same tests to show that female swordtails are strongly attracted to males with dark vertical bars. To avoid any bias the female might have for a particular side of the tank, Fernandez then switched the males. Two days later, he conducted the trials again, this time changing which male received the painted skin cancer spot. The female consistently chose the male with the dark pigmented marking in two of the three populations, he said.

Unsung Hero’s of the London Aquaria Society Over the years there have been so many Members who have given up their time to help run our club, never asking for anything in return. This year, I hope to mention some of those Members to tell them how much we appreciate what they do for us. Last, but certainly not least is Steve McDonald. Steve has been with the club for at least 20 years that I know of. He works very hard when it comes to taking care of the clubs needs such as, getting the room ready for each monthly meeting, with many of the Members helping him to put things right at the end. He helps to set up for our yearly auction & show and works in the kitchen for these Auctions. Steve, on behalf of the London Aquaria Society, we would like to thank you for all the work you have done for Thanks Steve this club.

Bill has a presentation with lots of past memories good and bad and his love for big fish. This will be a great talk from Bill as he has a lot of knowledge in the tropical fish hobby. I hope everybody enjoyed the get to know you talk we had at our last meeting, it was nice to share the good and the bad of the hobby and sharing our personal experiences. A big welcome to the new members that were present. March will be a night to learn about fixing a leaky tank. If all goes as planned, this should be a very interesting evening because our own John Swick will be doing a presentation for us. The fish show for February will be in Anabantids (Bettas, Gouramis, Paradise Fish) and the Open Class and the Open Class for Plants. We also have the Bowl Beautiful, so come out and try your luck. It’s always fun to participate. The auction will be there as usual. Happy Valentines Day and be nice to your honey.

Picture from Lake Dunlap, TX. Thanks Laurel & Bob London Aquaria Society Page 3 APISTOGRAMMA NAME GAME Submitted by: Doug Capel, London Aquaria Society, January 2015 I have always been amused when I listen to other fish nuts like me discuss the various fish they keep. Invariably the pronunciation of the names gets terribly mangled in a slightly different way by no matter who is talking. I am not educated in the classics of Latin or Greek, so I guess I am no better than anyone else. Getting past the pronunciation issue, I have taken great interest in the etymology of the names. My current passion is for the various Apistogrammas, and the following is a focus on the names of the more common members of the Apistogrammas group: The list hereunder shows the various scientific names, which are always shown in the format of scientific nomenclature. The Latin-derived scientific names are capitalized except for the specific and subspecific names. The generic, specific, and subspecific names are underlined or italicized. Generally Latin or Greek are the languages used in scientific naming. Even where a species is named after, say, an English person, that person's name is likely to be "Latinized" by adding a suffix "-i" (if it's named after a male), or "-ae" (if it's named after a female). So, a species named after Paul would be called pauli or, if it was named after Elizabeth it would be elizabethae. In order to be officially registered, a newly discovered species must first be given a scientific species-name. This must differ from all previously allocated names and will be valid throughout the world, irrespective of national language. To be complete, the scientific name includes the authority or person who described the species, followed by the date. The first consideration in this article is a definition of the Genus name Apistogramma: Originally the genus was called Heterogramma, but it was discovered that this name was already taken for a genus of beetles, and given that it was already taken, could not be used. In 1913 Regan discovered the prior use and suggested an alternate name Apistogramma. From the Greek, Apisto means irregular or broken, and gramma means line. This describes the key delineating feature of the genus, the interrupted lateral line. An examination of this genus is appropriate as it is one of the fastest growing as many species have been discovered and described in relatively recent years. The table set out hereafter attempts to show the meaning and/or origin of the names: A. agassizi Steindachner, 1875 after Dr. Louis Agassiz. A. atuhualpa Romer, 1997. Named after last king of the Incas, murdered by Pizzaro in 1533. A. baenschi Kullander, 1998 named for Hans A Baensch, publisher of the Cichlid Atlas.

Just imaging winning the lottery and dropping everything to go on an exploration trip to the Amazon to find a heretofore undescribed Apistogramma. My dream has been to discover a new fish. Based on the above, the following are the minimum requirements for the ultimate ichthyological ego trip – to have a fish named for you. Get a PhD in ichthyology. Ask Sven Kullander to be your child’s godfather. Get your second wife Elizabeth’s concurrence. Members of your exploration team should avoid getting murdered. Conquistadors are to be avoided. Write Uwe Romer and tell him how much you just loved his Cichlid Atlas. Discover an Apisto with more or less than 2 bands, all the Latin names for 2 are used up. Take up Belgian citizenship and win the 6-49 (in that order). Have your fish exporter sign a non-competition agreement. Lastly, do your exploring on a river that already has a fish named after it. Apistogramma capeli has a nice ring to it, don’t you think? Bibliography: South American Dwarf Cichlids by Hans J. Mayland & Dieter Bork – 1997 Mergus Cichlid Atlas by Dr. Uwe Romer - 2000 Thanks Doug Fish cancer gene linked to pigment pattern that attracts mates cont’d from front page But the research suggests that the swordtail fish population also keeps the prevalence of the cancer gene in check. A third population of females in the study rejected the males painted with the pattern that can form melanomas. The scientists suspect that’s because the third group had a higher ratio of both males and females with the gene for skin cancer, which increases the likelihood of too many offspring inheriting the gene and dying off. London Aquaria Society Page 7 Fish cancer gene linked to pigment pattern that attracts mates cont’d from page 7 Swordtail fish usually live for 1.5 to 2 years in the wild and sexually mature at 4.5 months. The ones with the skin cancer gene can develop melanomas at about 7 months and die a few months later. “Melanoma formation cuts the reproductive life cycle in half,” Fernandez said. “It has a huge cost for males.” But during the few months when the male is sexually mature and healthy, he also can produce a lot of offspring, he noted. The swordtail melanoma has been studied since the 1920s, and scientists previously believed that fish developed the cancer only in captivity. But in the recent study, 10 percent of the swordtails collected from the third population in Mexico also exhibited the disease, said Fernandez, who joins the University of Texas M.D. Anderson Cancer Center this fall as a postdoctoral fellow. He hopes to conduct further studies on the habitat, such as whether stronger exposure to the sun’s UV rays might be driving more instances of skin cancer in the wild. The study was funded by a National Institutes of Health Research Service Award predoctoral fellowship to Fernandez and a National Science Foundation grant to Morris. Morris is a member of Ohio University’s Ohio Center for Ecology and Evolutionary Studies. Contact: André Fernandez, (616) 901-4639, af180603@ohio.edu; Molly Morris, (740) 707-3431, morrism@ohio.edu.

Foster & Smith Educational Staff www.liveaquaria.com/PIC/article.cfm?aid=15 Today's aquarium filters offer a wide variety of options to keep your aquarium water clean and healthy. When choosing filtration, base your decision on the size of your aquarium, as well as number of fish you hope to keep. To achieve the absolute best water conditions, you may need to use more than one type of filter. Air-driven Internal Filters: These small, inexpensive box-like or foam filters are ideal for rearing fry, hospital aquariums, and small aquariums with very small fish. They are strong enough to maintain good water conditions, yet gentle enough to keep small aquarium inhabitants free from harm. Most of these devices provide mechanical, chemical, and biological filtration. These filters are placed inside the aquarium and allow you to locate your aquarium very close to adjacent walls to save space. Undergravel Filters: As their name suggests, these filters are placed underneath a layer of aquarium gravel. These filters move water through the gravel to create conditions favorable for biological filtration. Once the beneficial bacteria colonize the gravel, they begin to efficiently break down waste materials. Undergravel filters are relatively inexpensive and rely on either an air pump or powerhead to function. Undergravel filters are primarily biological filters. However, many models feature a replaceable cartridge placed at the end of the rigid tubing to provide supplementary chemical (activated carbon) or mechanical (filter floss) filtration. These filters are available for small or large aquariums but are best suited for aquariums with a light fish load. Internal Power Filters: Imagine a power filter you can completely place underwater. These handy filters have the space-saving feature of air-driven internal filters and the power and versatility of standard power filters. These filters provide excellent filtration and water movement since they are generally placed near the bottom of the aquarium. Waste products are removed before they have a chance to settle on the bottom of the aquarium. They are made for smaller aquariums, generally under 20-gallons. London Aquaria Society Page 9 Aquarium Filter Selection Guide cont’d from page 9 Power Filters: Power filters are probably the most widely used aquarium filters - and for good reason. They are very easy to use and provide excellent biological, chemical, and mechanical filtration. They are designed to hang off the back of your aquarium and are the perfect filter for most popular aquarium sizes housing a variety of tropical fishes. Replaceable filter cartridges make maintenance simple and convenient. Newer models feature either a biological filter pad or BIO-wheel to provide extra pollution removing power. Canister Filters: Canister filters provide superior mechanical, chemical, and biological filtration for larger aquariums or aquariums with a lot of fish. The body or "canister" portion of the filter is significantly larger than most power filters - imagine how much media canister filters are able to hold! Depending on the model, canister filters will have one to three (or more) large media baskets to hold different filter media types. Each media type is layered on top of each other to maintain excellent water quality. Compared to power filters, canister filters require slightly more effort to set up and maintain. However, you will be amazed by their filtering power. These multipurpose filters are ideal for African and South American Cichlid aquariums, saltwater aquariums, as well as freshwater planted aquariums. Wet/Dry Filters: Wet/dry filters provide the ultimate in biological filtration. They are great for saltwater fish-only aquariums or any large aquarium setup that demands efficient biological filtration. These filters are called wet/dry filters because the biological filter media is exposed to both aquarium water (wet) and a significant amount of air (dry). This design creates the ideal environment for large numbers of beneficial bacteria to actively process waste materials. In general, these aquarium filters require the most effort to set up since they need to be installed or plumbed to the aquarium in a rather elaborate manner. However, for the creative and avid aquarium hobbyist, setting up a wet/dry filter provides the ideal opportunity to construct a custom, one-of-a-kind filtration system. Most models are designed for placement under an aquarium and require an overflow box on the back. Most wet/dry filters include a sump/reservoir that holds auxiliary equipment along with the required water return pump. London Aquaria Society Page 10 Sailfin Pleco (Glyptoperichthys gibbiceps) Leopard Pleco, Gibby, L083, L165 http://www.theaquariumwiki.com/Glyptoperichthys_gibbiceps Additional scientific names Pterygoplichthys gibbiceps, Ancistrus gibbiceps, Liposarcus altipinnis Origin: These impressive fish come from the Orinco and Amazon River basins in Brazil, Ecuador, Peru, and Venezuela. They are found in sluggish, slow river waters and move to flooded areas during the wet season. They love to burrow into muddy banks to make their homes. Sexing: These fish can be sexed by viewing their genital papilla on their belly, only really apparent in mature fish, the males will small thick stump that protrudes from the fish's undercarriage, the females are less obvious and lies flat to the body. Tank compatibility: Larger individuals are territorial towards other Plecos. A tough fish that can live with semi-aggressive and moderately aggressive tank mates. One best kept to a tank due to tendency towards being territorial and being quite messy fish. Best not kept with very aggressive fin-nippers due to it's tall dorsal fin. Diet: Will take most vegetarian foods including algae wafers and blanched vegetables, will eat soft brown algae in the tank. When mature will also take prawns and similar. Feeding regime: Feed once or twice a day, may be more active towards feeding when the tank lights are off. Environment Specifics: Requires exceptional filtration, although not fussy with water quality, this fish produces a high amount of waste. Appreciates wood in the tank and places offered as hiding spots. Planting is not ideal as although this fish won't generally eat the plants, they will uproot them. Behaviour: Territorial once mature. Will out compete other catfish for food. Identification: A large and attractive Pleco with a large dorsal which does appear saillike when raised, giving this fish its common name. The body colouration is a light brown to black in base colour with dark brown to black spots going into the fins also. The fins occasionally have a reddish brown edging to them. Albino variations have been seen.

One day it was there and the next day it was gone, replaced by a giant crate of 50 metres (164 feet) wide and 30 metres (98 feet) deep. Although its cause has not been verified, it is likely that changes in the soil, or possibly a dry water table could be reasons for the water disappearing - literally overnight. Now trees cling to the edge of this sinkhole near the village of Sanica where local folks ponder the situation and children try to find a new pond in which to fish.

Thanks for the laughs Dad London Aquaria Society Page 13 Peacock Eels http://www.aquaticcommunity.com/mix/peacockeels.php The Peacock eel is also known as the Siamese Spiny Eel, and its scientific name is Macrognathus siamensis. It belongs to the Family Mastacembelidae, the Spiny eel family. Just like many other eels, the Peacock eel has an elongated body. Wild specimens often grow up to 30 centimeters long (12 inches), but in captivity the will often stay around 15 centimeters (6 inches). The Peacock eel has a dark brown back and light brown flanks, while they belly is much lighter. You can see a fine yellow line that runs from the snout and all the way to the caudal fin. At the dorsal and caudal fins the Peacock eel is decorated with five eye-spots. The colors and patterns will vary between geographically separated populations. The native environment for the Peacock eel is slow flowing and densely grown rivers and streams in India, Sri Lanka, Thailand, Sumatra and Malaysia. It is a bottom living creature that likes to bury itself in silt, sand or fine gravel, and only display a small part of its head. It prefers to forage for food at dusk. Wild Peacock eel will eat worms, crustaceans and larvae and keeping them on a similar diet of live food in the aquarium is recommended. Live brine shrimp, blood worms, mosquito larvae and cyclops are all good suggestions. A small Peacock eel needs to be housed in an aquarium that is at least 61 centimeters long (24 inches) and has a volume of 75 liters (20 gallons). If your Peacock eel grows larger, you must move it to a bigger aquarium. The water conditions in the aquarium should resemble those found in slow flowing Southeast Asian rivers. You can add some salt to the water. The ideal pH is 7.0 and the ideal dH is 10, but the Peacock eel will tolerate a pH between 6 and 8 and a dH in the 6 to 25 range. This fish like warm waters so make sure that the temperature stays between 23 and 28° C (73 and 82° F). The Peacock eel is commonly kept in community aquariums since it is a quite peaceful fish. Avoid keeping it with small fishes, since they will be considered food. Similarly sized and peaceful fish that appreciates the same water conditions as the Peacock eel are much better companions. When the Peacock eel has been introduced to a new home, it is usually very shy and prefers to stay hidden most of the time. If you provide it with an aquarium environment that makes it feel safe, it can become very friendly over time. As mentioned above, the Peacock eel inhabits densely grown waters, and keeping this fish in an aquarium with plenty of plants is therefore recommended. Your Peacock eel will also appreciate PVC pipes that it can hide inside, and sheltered spots created by rocks, roots and wood. As of 2006, there are no recorded instances of Peacock eel reproduction in aquariums. Distinguishing between male and female Peacock eels can be a bit difficult, but the maA number of peacock eels hiding in the same spot. ture female will have a plumper body.

Allen, WWF Published June 27, 2011 New Guinea has some of the most beautiful freshwater fish found anywhere, including tiny and vibrantly colored rainbow fish, according to WWF. Seven new species of rainbow fish, including Chilatherina alleni (pictured) were found in New Guinea during the ten-year period. "New 'Rainbow Glow' Jellyfish Found.") Ergasilus (gill maggots) www.fish-disease.net/diseases/gill_maggots.php Symptoms: Infected fish can be seen with small maggots attached to the gills, gill plates, and inside the mouth. Severe infestations can cause severe gill damage, emaciation, anemia, and even death. Cause: The crustacean Ergasilus. Treatment: Treat the entire aquarium or pond with organophosphorus insecticides such as metriphonate. Medicate the aquarium (0.25 to 0.4 mg/L) for 7-10 days. Some fish, such as piranhas, are sensitive to this medication so treat them separately using potassium permanganate with 30 minute baths for 7-10 days. It is important to improve your aquarium or pond's water quality, being careful not to overfeed. London Aquaria Society Page 17 GIVE YOUR FISH WHAT THEY DESERVE!
