Oscar Fish color codes and composition in a live tank


Oscar or Astronotus ocellatus is a genus of cichlid fish known by a number of common names, including tiger oscar, velvet cichlid and marble cichlid. A. In tropical South America, where the species naturally lives. Ocellatus specimens are often found for sale as food fish on local markets. Fish have been introduced to other regions, including China, Australia and the United States. It is considered to be a common aquarium fish in Europe and the United States.

Examples of Oscar fish have been reported to grow to around 45 cm (18 inches) in length and 1.6 kilograms (3.5 lb) in weight. The wild-caught forms of the species are typically darkly colored with yellow-ringed spots or ocelli on the caudal peduncle and on the dorsal fin.

Such ocelli have been suggested to restrict the fin-nipping by piranha (Serrasalmus spp.) co-occurring with A. The ocellate in its natural environment. The species is also capable of rapidly altering its coloration, a trait that facilitates ritualized territorial behavior and combats the behavior of conspecifics. Juvenile oscars are distinct in color from adults, striped with white and orange wavy bands and with spotted eyes.

Although the species is widely regarded as sexually monomorphic, males have been reported to grow faster and, in some naturally occurring strains, males are shown to have dark blotches at the base of their dorsal fins. The species achieves sexual maturity at around one year of age and continues to reproduce for 9 to 10 years. Frequency and timing of spawning may be correlated with the frequency of rain. A. Ocellatus fish are bi-parental substrate spawners, but detailed information on their reproduction in the wild is scarce.

In captivity, pairs are known to select and clean generally flattened horizontal or vertical surfaces on which to lay their 1,000 to 3,000 eggs, just a guess for the number of eggs. Like most of the cichlids, A. Ocellatus practices brood care, although the duration of brood care remains unknown in the wild.

Most of the fish eaten by A. Ocellatus in the wild is a fairly sedentary genus of catfish, including Bunocephalus, Rineloricaria and Ochmacanthus. The species uses a suction mechanism to capture prey and has been reported to exhibit "laying-on-side" death mimicry similar to Parachromis friedrichsthalii and Nimbochromis livingstonii.

The species also has an absolute requirement for vitamin C and, in its absence, develops health problems. Captive oscars generally eat fish food intended for large carnivorous fish: crayfish, worms and insects such as flies, crickets and even grasshoppers.

It is interesting to note that Oscars will often claim an aquarium area and will be very aggressive towards other fish caught on their newly established territory inside the aquarium or lake. The size of the territory varies depending on the size and the aggressiveness of the fish, based on its surroundings. Once the Oscar has formed a territory, it will vigorously defend it by chasing away other fish.
