Cichla ocellaris
A large predatory cichlid from rivers of northeastern South America, yellow-green with dark bars and a ringed eyespot on the tail base. Recorded to 74 cm, it is also a noted game fish.
Cichla ocellaris is a large cichlid known as the peacock bass or butterfly peacock bass. FishBase restricts its range to the Marowijne drainage (Suriname, French Guiana) through to the Essequibo (Guyana); Cichla from other regions are usually treated as other species. Several Cichla species are traded as 'peacock bass', so check the scientific name and origin before buying. It is recorded to 74 cm TL and 6.8 kg. It lives in schools in rapids and rocky, moderately deep waters and feeds almost entirely on small fish. It reproduces year-round with a peak at the start of the rainy season. It has been introduced for sport fishing to places such as the USA and Singapore. It is often sold as a cute juvenile of about 5 cm, but it becomes a very large predator that requires an extra-large tank for life.

Piscivore (fish, prawns, mussels)
24-27°C (FishBase), pH 6.5-7.0, up to 15 dH (Seriously Fish). A messy feeder that needs powerful filtration such as external or sump systems.
Adults may exceed 70 cm and need open swimming space: an extra-large tank much longer than the adult fish and deeper than its body length, for life. Keep décor to large driftwood and robust plants.
Territorial and moderately aggressive; eats any fish it can swallow. Companions are limited to similarly large fish such as arowanas or big catfish, and that needs a huge tank.
Piscivorous. Feed meaty foods such as prawns, mussels and fish pieces, and wean it onto pellets for predatory fish.
Few reports of captive breeding. Mature males develop a nuchal hump.
Sold as small juveniles but grows quickly into a large fish. Never release it into the wild.
Advanced. This is an advanced-level species. It requires specialized equipment and advanced husbandry skills with precise environmental control.
The ideal temperature for Peacock cichlid is 24〜27℃. Avoid sudden temperature changes and maintain a stable environment.
Peacock cichlid typically reaches Up to 74 cm TL and 6.8 kg (FishBase) as an adult. Size may vary depending on care conditions and individual genetics.
Peacock cichlid feeds on: Piscivore (fish, prawns, mussels). Aim for a balanced diet with appropriate feeding frequency.
