The largest species in the genus, the speckled peacock bass ( C. Where established as an introduced species, they may become invasive and damage the ecosystem because of their highly predatory behavior, feeding extensively on smaller native fish. Singles have been caught elsewhere, including Australia, but do not appear to have become established there. This has resulted in their accidental (escapees from fish farms) or deliberate (release by fishers) introduction to regions outside their native range, both elsewhere in South America, and in warm parts of North America and Asia. Peacock bass are important food fish and are also considered valuable game fish. Despite the common name and their superficial similarity, they are not closely related to other fish known as bass, such as the North American largemouth bass ( Micropterus salmoides). They are sometimes referred to in English by their Brazilian name tucunaré or their Spanish name pavon. These are diurnal predatory fishes native to the Amazon and Orinoco basins, as well as rivers of the Guianas, in tropical South America. Peacock bass or Brazilian tucunaré are large freshwater cichlids of the genus Cichla.
