Overview
Cichla orinocensis, the Orinoco or butterfly peacock bass, is a large predatory cichlid described by Alexander von Humboldt in 1821. Adults bear three large gold-edged dark spots along the body, with a fourth on the tail, and lack dark markings on the gill cover. It is a prized game fish.
Taxonomy
- Family: Cichlidae
- Genus: Cichla
- Scientific name: Cichla orinocensis
- Described by Humboldt, 1821
Habitat
The species is native to the Rio Negro and Orinoco River basins in northern South America. It mainly occurs in blackwater rivers, prefers slow-moving and shallow waters and tolerates more turbid conditions than other peacock bass.
Tank requirements
- Minimum tank volume: 1500 L or more
- Temperature: 26-30 °C (79-86 °F)
- pH: 5.0-7.0
- GH: 2-10 °dGH
- Maximum size: about 62 cm SL
- Lifespan: 10-15 years
Wikipedia reports a maximum standard length of about 62 cm. Given its adult size, this species requires very large aquariums; the water ranges above follow the verified KB record.
Diet
Cichla orinocensis is a piscivore that hunts smaller fish. In the aquarium it requires a carnivorous diet of suitable whole or prepared meaty foods, fed twice daily.
Compatibility
Aggressive and predatory, it should only be combined with large, robust tankmates such as big plecos, silver dollars or other large cichlids in very spacious tanks. Small fish and most cichlids are unsuitable.
Conservation status
IUCN Red List: Least Concern.
Cichla orinocensis Breeding Guide
Overview
Cichla orinocensis, the Orinoco peacock bass, is native to the Rio Negro and Orinoco basins, mainly occurring in blackwater rivers and slower, shallow waters. It reaches up to about 62 cm in standard length and is a large predatory member of the genus Cichla, which spawns on the substrate and guards its young.
Sexing
In Cichla, many adults, primarily males but also some females, develop a pronounced forehead hump (nuchal hump) shortly before and during the rainy season when spawning occurs.
Spawning Behavior & Trigger
Peacock bass generally spawn during the rainy season. As substrate spawners, pairs prepare a hard surface and deposit their eggs on it. Reproduction in the genus is tied to the seasonal flood pulse of their native rivers.
Egg & Fry Care
Cichla species show biparental care: one or both parents vigilantly guard the eggs and the resulting fry school against predators. This guarding behavior is documented across the genus.
Common Challenges
The dominant challenge is sheer adult size combined with predatory aggression, which makes pair formation and brood rearing in a home aquarium unrealistic. Controlled spawning is achieved in ponds and aquaculture settings.
