The Trondo mainty (Ptychochromoides betsileanus), is a species of cichlid in the family Cichlidae. It is endemic to the Onilahy River Basin in southwestern Madagascar. Its remaining range covers less than 10 square kilometres (3.9 sq mi), and it is highly threatened by habitat loss, fishing and competition/predation by introduced species. Another cichlid from the same basin, Ptychochromis onilahy, is probably already extinct. The trondo mainty reaches a length of 24 centimetres (9.4 in) SL.
