Cichla ocellaris Breeding Guide

Breeding biology of the butterfly peacock bass Cichla ocellaris, a large biparental substrate spawner impractical to breed at home.

Overview

Cichla ocellaris, the butterfly peacock bass and type species of the genus, is native to the Marowijne and Essequibo drainages in the Guianas and the Branco River in Brazil. It has been widely introduced, including to Florida (1984), Hawaii and Puerto Rico. Maximum length is about 74 cm, with an average of 30-36 cm. It is a substrate-spawning, biparental cichlid.

Sexing

Across Cichla, many adults, primarily males but also some females, develop a pronounced forehead (nuchal) hump shortly before and during the spawning season.

Spawning Behavior & Trigger

Spawning occurs between April and September, peaking in May and June. Adults create large flat, hardened surfaces near the shore to serve as a spawning site, onto which the eggs are deposited.

Egg & Fry Care

Both adults are responsible for protecting the young from predators, demonstrating the biparental guarding typical of peacock bass.

Common Challenges

The large adult size and predatory nature make pair formation and brood rearing in home aquaria unrealistic; controlled spawning is achieved in pond and aquaculture settings.
