  • Grows up to 74 cm in length
  • Named for peacock-like spot on tail
  • Popular sport fish in south Florida
  • Controls tilapia and oscar populations
  • Cannot survive in cold or salty water

What it is

This large cichlid resembles a largemouth bass in shape but displays vibrant colours ranging from yellow and green to orange. Its most distinct feature is a black spot with a yellow halo on the tail fin, which looks like a peacock feather. Three vertical black lines run down its sides, though these may fade in older specimens. Adults typically measure 30 to 36 centimetres but can grow up to 74 centimetres.

Where it lives

Native to the Marowijne and Essequibo river systems in the Guianas and the Branco River in Brazil, this fish prefers tropical waters. It has been introduced to south Florida, specifically Miami-Dade and Broward counties, where it spreads through warm canal networks. Small populations exist in Texas and Louisiana. Large numbers were also released into Tri An Lake in Vietnam. It cannot survive in water colder than 15 degrees Celsius or with high salt content.

How it lives

As a predatory species, it hunts other fish during daylight hours when visibility is high. It uses speed and a large mouth to capture prey. In Florida, it helps control overpopulated tilapia and oscar populations. The fish often hides in shaded areas under trees, bridges, or culverts. It thrives in slow-moving bodies of water such as lakes, ponds, and rock pits.

Breeding and life cycle

Spawning occurs between April and September, peaking in May and June. Adult pairs prepare large, hardened flat surfaces near the shoreline for egg deposition. Both parents guard the eggs against predators after they are laid. Growth is rapid during the first 16 to 18 months, reaching average size quickly. The typical lifespan ranges from six to ten years.

Fish and people

Anglers consider it a premier sport fish in south Florida, generating significant economic activity. Fishermen use live shiners, topwater jigs, or jerkbaits to catch them from boats or shores. Regulations limit daily catches to two fish under 43 centimetres. The meat is white, flaky, and mild, making it popular for consumption. It serves as a tool for fisheries management by controlling invasive prey species.

Status and threats

Studies indicate that its introduction to Florida does not harm local fish communities. Instead, it acts as a management tool for balancing ecosystems. Uncertainty remains regarding some introductions outside its native range, as hybrids or related species may be involved. It is restricted to specific warm regions due to temperature and salinity tolerances.
