Butterfly peacock bass
Cichla ocellaris, sometimes known as the butterfly peacock bass ("peacock bass" is also used for some of its relatives), is a very large species of cichlid from South America, and a prized game fish. It reaches 74 cm (29 in) in length. It is native to the Marowijne and Essequibo drainages in the Guianas, and the Branco River in Brazil. It has also been introduced to regions outside its natural range (e.g., Florida, Hawaii, and Puerto Rico), but some uncertainty exists over the exact identity, and at least some of the introductions may involve another Cichla species or hybrids. It is frequently confused with C. monoculus. Studies conclude that the introduction of Cichla ocellaris does not negatively impact fish communities in Florida, making it an effective fisheries management tool.
Native to the tropical Americas, the true Cichla ocellaris is restricted to the Guianas. The species thrives in warm, slow-moving bodies of water including lakes, ponds, canals, and rock pits. Like other species of bass, they tend to inhabit shaded areas under trees, bridges, and culverts. Butterfly peacock bass cannot survive in salinities exceeding 18 ppt, nor can they live in temperatures less than 60 degrees Fahrenheit.
In 1984, the Florida Fish and Game Commission introduced the species to the lakes and rivers of Miami-Dade County, in south Florida. Upon introduction, roughly 10,000 young fish were introduced to the Miami-Dade County area via releasing the juveniles into the lakes and canals. Distribution throughout the area can be attributed to the travel of this species through the warm, freshwater canals of Florida. It is thought that these fish inhabit up to 300 miles (500 km) of canals specifically. Due to the fish's inability to tolerate salt water and low water temperatures, this species of fish is typically found only in the Miami-Dade and Broward County areas of Florida, with a few sightings in Texas and Louisiana.
This species has also been introduced in large numbers to Trị An Lake in Vietnam
The introduction of the butterfly peacock bass to Florida has successfully aided in managing and controlling tilapia and oscar populations that once were a threat via overpopulation. The fish primarily feeds on fish allowing for them to be roleplayers in the balancing of a habitat. These fish typically feed during daylight hours where visibility is better for hunting. Like other bass, they use their incredible speed and large mouth to capture prey.
