Peacock Bass

Peacock Bass is the common name for several large cichlid species in the genus Cichla, native to the rivers and lakes of the Amazon and Orinoco basins in South America. Despite the name, they are not true basses but predatory cichlids related to tilapia. They have been widely introduced outside their native range, most famously establishing thriving populations in South Florida canals, where they are now a popular sport fish. Peacock Bass are apex predators within their native freshwater ecosystems and are prized for their vivid coloration, aggressive strikes, and the distinctive ocellated spot at the base of the tail that gives the group its name.

Peacock Bass have a robust, elongated body with a golden-green to olive-yellow ground color and three bold dark vertical bars, giving them one of the most striking color patterns of any freshwater fish.

• Distinctive black eyespot (ocellus) ringed in gold at the base of the tail, resembling a peacock feather marking
• Large mouth and prominent spiny dorsal fin
• Mature males develop a fatty hump on the forehead during breeding season
• Bright orange, red, or golden highlights on fins, especially in breeding adults
• Typically 40-70 cm, though some species and individuals exceed 90 cm

Peacock Bass are native to warm, slow-moving rivers, oxbow lakes, and floodplain lagoons of the Amazon and Orinoco river basins in South America, favoring clear to slightly stained water with abundant submerged structure. They prefer water temperatures generally above 20°C and are intolerant of cold, limiting their range to tropical and subtropical latitudes. Introduced populations thrive in the canal systems of South Florida and other warm freshwater environments around the world where they have been stocked, always remaining in structurally complex habitats near cover such as fallen timber, docks, and vegetation.

Peacock Bass are aggressive, visually oriented ambush predators that patrol structure-rich shallows and strike fast-moving prey with explosive speed. They feed primarily on smaller fish, using their large mouths to engulf prey whole. Pairs form monogamous bonds during spawning, building and vigorously defending nests, with both parents guarding eggs and free-swimming fry against intruders. This strong parental guarding behavior, combined with their aggressive territorial nature, makes them formidable predators that can significantly reduce populations of smaller native fish in waters where they have been introduced.
