"Aquaculture Crsp 22nd Annual Technical Report" (PDF). ocellatus fish are biparental substrate spawners, though detailed information regarding their reproduction in the wild is scarce. Frequency and timing of spawning may be related to the occurrence of rain. The species reaches sexual maturity around one year of age, and continues to reproduce for 9–10 years. Reproduction Īlthough the species is widely regarded as sexually monomorphic, males have been suggested to grow more quickly, and in some naturally occurring strains, males are noted to possess dark blotches on the base of their dorsal fins. The species is limited in its distribution by its intolerance of cooler water temperatures, the lower lethal limit for the species is 12.9 ☌ (55.22 ☏). Feral populations also occur in China, northern Australia, and Florida, USA as a byproduct of the ornamental fish trade.
In its natural environment, the species typically occurs in slow-moving white-water habitats, and has been observed sheltering under submerged branches. ocellatus is native to Brazil, Colombia, Ecuador, Guyana, French Guiana, Suriname, Peru, and Venezuela, and occurs in the Amazon River basin, along the Amazon, Içá, Negro, Solimões, and Ucayali River systems, and also in the Approuague and Oyapock River drainages.
