Description

The peacock bass (Cichla ocellaris) is a large, predatory cichlid from northern South America. The species has an elongate, yellow-green body with three dark vertical bands and a conspicuous, black-rimmed eyespot (ocellus) on the caudal peduncle, resembling a peacock's eye and giving the species its name. It can reach about 74 cm and inhabits calm, moderately deep waters and rapids with a rocky bottom. As a fast ambush predator it hunts almost exclusively small fishes. The peacock bass is a highly prized sport fish and valued food fish; beyond its native range it has been introduced worldwide and has become invasive in places.
