Trondo mainty

The trondo mainty (Ptychochromoides betsileanus) is a critically endangered species of cichlid endemic to the Onilahy River Basin in southwestern Madagascar. Its remaining range covers less than 10 km2 and it is highly threatened by habitat loss, fishing, and competition with/predation by introduced species. Another cichlid from the same basin, Ptychochromis onilahy, is probably already extinct. The trondo mainty reaches a standard length (SL) of 24 cm.
