Album Info:
(DSC05025) At the Oceanarium "Agos" (Flow): Astronotus ocellatus is a species of fish from the cichlid family known under a variety of common names including oscar, tiger oscar, velvet cichlid, or marble cichlid. In South America, where the species naturally resides, A. ocellatus are often found for sale as a food fish in the local markets. The fish can also be found in other areas including China, Australia, and the United States. Although its slow growth limits its potential for aquaculture, it is considered a popular aquarium fish. A. ocellatus have been reported to grow into a length of 34 cm (approximately 15 in) and a mass of 1.6 kg (2.6 lb). The wild caught forms of the species are typically darkly coloured with orange ringed-spots or ocelli on the caudal peduncle and on the dorsal fin. It has been suggested that these ocelli function to limit fin-nipping by piranha (Serrasalmus spp.) which co-occur with A. ocellatus in its natural environment. The species is also able to rapidly alter its colouration, a trait which facilitates ritualised territorial and combat behaviours amongst conspecifics. A. ocellatus is native to Peru, Colombia, Brazil, and French Guiana and occurs in the Amazon river basin. (Taken from http://en.wikipedia.org/wiki/Oscar_(fish ))
