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.




Recent news

Baltic cod are shrinking due to overfishing
(8/26/2008) By comparing Neolithic cod with contemporary cod, researchers have discovered that the species has evolved over a relatively short period due to overexploitation by humans. According to a paper published in Proceedings of the Royal Society B, contemporary cod attain adulthood earlier and are generally smaller than their ancestors.

DNA study reveals new 1,000-pound grouper species
(8/21/2008) DNA analysis has revealed that a 1,000-pound grouper found in both the Atlantic and Pacific Oceans is actually two different species.

Coal burning may make food supplies toxic
(8/18/2008) Coal burning is contaminating the Arctic, and may be affecting human health and polar ecosystems, warn scientists writing in the online early edition of the Proceedings of the National Academy of Sciences.

The long-ignored ocean emergency and what can be done to address it
(8/18/2008) This year has been full of bad news regarding marine ecosystems: one-third of coral species threatened with extinction, dead-zones spread to 415 sites, half of U.S. reefs in fair or bad condition, increase in ocean acidification, tuna and shark populations collapsing, and only four percent of ocean considered pristine. Jeremy Jackson, director of the Scripps Center for Marine Biodiversity and Conservation at the University of California, San Diego, synthesizes such reports and others into a new paper, published in the journal Proceedings of the Naional Academy of Sciences, that boldly lays out the scope of the oceanic emergency and what urgently needs to be done.

How sustainable is your canned tuna? It depends on the retailer
(8/13/2008) To aid concerned tuna-lovers, Greenpeace has ranked eight of the top canned tuna retailers in order from most sustainable to least. Canned tuna from John West, the biggest retailer of tuna in the UK, proves to be the worst of the lot, whereas Salinburys is the most environmentally-friendly. In a press release Greenpeace said that Salinburys is "the only tinned tuna brand that is fished using sustainable methods".
