species of fish

Paretroplus is a genus of fishes in the cichlid family, all of which are endemic to lakes and rivers of Madagascar. The vast majority are threatened and restricted to the northwestern part of the island. Only P. polyactis is found in the southern half of Madagascar and only P. polyactis and P. gymnopreopercularis are found in eastern drainages. Most are restricted to freshwater, but at least P. polyactis and P. maromandia can also be seen in brackish habitats.

Etroplinae is a subfamily in the cichlid family of fishes. The subfamily includes 3 genera (and about 16 species) : Etroplus and Pseudetroplus, which are the only cichlids native to India and Sri Lanka, and Paretroplus from Madagascar (other genera native to this island are in the subfamilies Paratilapiinae and Ptychochrominae).
