Kyle, Dicrossus (formally Crenicara) filamentosus and Filamentosa are the same fish. Different species is Crenicara punctulatum or punctulata (same fish) depends what book you have, I'm not sure which is correct. I understand from what I've read that C. Punctulatum/punctulata is the only cichlid species that changes sex. The dominant fish in the tank will change from female to male. Am I right or wrong??? Microgeophagus or Mikrogeophagus was formally Papiliochromis.
