CICHLIDS



CENTRAL AMERICAN CICHLIDS


Central American Cichlids are well-known for their pugnacious behavior and their stunning colors. Most of these cichlid are large, thus requiring large tanks. Most of the Central American Cichlid belong to a group known as Cichlasomines. These fish inhabit most types of water ways throughout Central America including lakes, streams, rivers, even underground water sources.


SIZE: Many of the fish in the group of Cichlasomines attain a size of 8" (20 cm) or more. In only a few species does the male not exceed 6" (15 cm)


TANK: Cichlasomines need a large, roomy tank with plenty of open swimming areas. Usually a 48" (122 cm) tank with a capacity of 55 gallons (209 L) will do. With their pugnacious nature, the tank should always have large hiding places created for fish that are harassed or ailing. An over-turned flowerpot, a large piece of wood, or a rocky cave will serve as an adequate retreat. Unfortunately, many Cichlasomines have a habit of destroying plants in some way: either eaten, up-rooted, or just demolished.


WATER: Cichlasomines usually inhabit water with a pH ranging from neutral (7.0) to alkaline (8.5). They prefer medium hard to hard with a dH from 8-20. The water temperature is usually from 72-81°F (22-27°C).


SB: Cichlasomines are known for their aggressive behavior. Battles between mates, males, and other species often leave the tank looking like a war zone. In these conflicts it is common to have an injured fish or fishes. The trick to avoiding these attacks is to provide a large open tank with plenty of territory for each fish. Do not over-populate the tank because cichlids in close confines will fight. Combine fish that have equal power and size so one fish does not have a disadvantage. With all species, the brood is carefully cared for and defended rigorously. Spawning time is probably the most dangerous for other fish in the tank. It is best to remove the other fish in the tank when pair begins to prepare for spawning


SC: Cichlasomines can be combined with each other, along with large, robust catfish such as Pimelodids, Loricarids, and Doradids. In one chooses not to keep a geographically correct aquarium, South American cichlids and African Haplochromines,Tilapia, andHemichromis are also acceptable. Large South American Characins are also suitable tank mates.


FOOD: Cichlasomines will eat almost any food. Most fish enjoy being fed an occasional feeder fish along with frequent helpings of earthworms,Tubifex, insects, insect larvae, and large crustaceans. They will also accept large flake foods, pellets, tablets, and such vegetables as spinach, peas, and lettuce.


B: To attempt breeding Cichlasomines, one must first find a compatible pair. This can be done by obtaining 6-10 juvenile fish and letting them pair off. When a pair that appears suitable for each other forms, use the pair for breeding. Cichlasomines for the most part, are open spawners, who lay large amounts of eggs on a rock, root, or plant. The female usually guards the egg, while the male aggressively defends the territory against all other fish. The parents continue their guard for the fry even when they are first free-swimming. The fry can be raised onArtemia nauplii, dry foods, and other small live foods.


BP: Usually breeding is not that difficult although the parents often cause many problems with their aggressive brood care.


R: The Cichlasomine group is undergoing taxonomic review, after genus ofCichlasoma was taxonomically orphaned. To avoid this controversy and ion lieu of any better suggestions, the fish formerly of Cichlasomawill be referred to with quotation marks "Cichlasoma." In parentheses will be the sub-groupings as suggested by Miller. This section will be organized into the sub-groupings.


DC: For the most part, Cichlasomines are hardy, but highly aggressive fish. They can be combined with each other in large tanks.

Atlantic sturgeon gains protection under the Endangered Species Act

(02/01/2012) The U.S. federal government has listed the massive and bizarre Atlantic sturgeon (Acipenser oxyrinchus) under the protection of the Endangered Species Act (ESA). Historically overfishing decimated the Atlantic sturgeon, while on-going threats include pollution and infrastructure, like dams and bridges that destroy habitat. Fishing for the Atlantic sturgeon has been banned since 1998, they are still caught as bycatch.


Photos: 46 new species found in little-explored Amazonian nation

(01/25/2012) South America's tiniest independent nation still hides a number of big surprises: a three week survey to the sourthern rainforests of Suriname found 46 potentially new species and recorded nearly 1,300 species in all. Undertaken by Conservation International's (CI) Rapid Assessment Program (RAP) the survey found new species of freshwater fish, insects, and a new frog dubbed the "cowboy frog" for the spur on its heel. While Suriname may be small, much of its forest, in the Guyana Shield region of the Amazon, remains intact and pristine. The Food and Agriculture Organization (FAO) estimates that 91 percent of Suriname is covered in primary forests, however this data has not been updated in over two decades.


Featured video: tuna industry bycatch includes sea turtles, dolphins, whales

(01/16/2012) A Greenpeace video, using footage from a whistleblower, shows disturbing images of the tuna industry operating in the unregulated waters of the Pacific Ocean. Using fish aggregation devices (FADs) and purse seine nets, the industry is not only able to catch entire schools of tuna, including juvenile, but also whatever else is in the area of the net.


Bycatch-reducing fish trap wins $20,000

(01/11/2012) An innovative fish trap that allows small non-target fish to escape won a new content by RARE Conservation and National Geographic to fund solutions to overfishing. Developed through studies in CuraƧao and Kenya with the Wildlife Conservation Society, the trap has gaps for juvenile fish to swim out of reportedly reducing bycatch by 80 percent. The entry won a $20,000 grant.


World's most expensive tuna

(01/05/2012) A 593 pound Pacific bluefin tuna sold for $735,000 (56.49 million yen) in Tokyo's Tsukiji market today. This beats the previous record price hit last year by over $260,000. Why so expensive? Bluefin tuna, considered the best sashimi and sushi in the world, have been fished to near extinction with the population of the Pacific bluefin the most stable to date.


Top 10 Environmental Stories of 2011

(12/22/2011) Many of 2011's most dramatic stories on environmental issues came from people taking to the streets. With governments and corporations slow to tackle massive environmental problems, people have begun to assert themselves. Victories were seen on four continents: in Bolivia a draconian response to protestors embarrassed the government, causing them to drop plans to build a road through Tipnis, an indigenous Amazonian reserve; in Myanmar, a nation not known for bowing to public demands, large protests pushed the government to cancel a massive Chinese hydroelectric project; in Borneo a three-year struggle to stop the construction of a coal plant on the coast of the Coral Triangle ended in victory for activists; in Britain plans to privatize forests created such a public outcry that the government not only pulled back but also apologized; and in the U.S. civil disobedience and massive marches pressured the Obama Administration to delay a decision on the controversial Keystone XL pipeline, which would bring tar sands from Canada to a global market.
