Ptychochromis
''Ptychochromis'' is a genus of cichlids endemic to rivers and lakes in Madagascar. One species ('' P. grandidieri'') can also be seen in brackish water.Stiassny, M.L.J. & Sparks, J.S.

''American Museum Novitates, 3535: 1-56.'' Most species in this genus are threatened, and '' P. onilahy'' is probably extinct. Most reach a length of 15 to 20cm, but '' P. insolitus'' reaches 25, while ''P. grandidieri'' and '' P. oligacanthus'' reach 35 and 20cm respectively. The largest species was P onilahy which may have reached as much as 45cm if reports of fishermen are to be believed.

Ptychochromis Insolitus
''Ptychochromis insolitus'', also known as the Mangarahara cichlid or joba mena, is a species of cichlid endemic to certain river systems in northern Madagascar.Stiassny, M., and Sparks, J. S. (2006). ''Phylogeny and Taxonomic Revision of the Endemic Malagasy Genus Ptychochromis (Teleostei: Cichlidae), with the Description of Five New Species and a Diagnosis for Katria, New Genus.'' American Museum Novitates 3535. This critically endangered fish is threatened by habitat loss and competition from introduced species; after the last-known female was killed during a breeding attempt, its conservation received significant international attention as London Zoo launched a media campaign to identify any remaining individuals. A remnant population was discovered by aquaculture entrepreneur Guy Tam Hyock in 2013, and breeding programs in Madagascar and at Toronto Zoo have resulted in thousands of successful hatchlings.

''Ptychochromis oligacanthus'' is a species of cichlid endemic in fresh water habitats in the western part of the Antsiranana Province in Madagascar.Stiassny, M., and Sparks, J. S. (2006). ''Phylogeny and Taxonomic Revision of the Endemic Malagasy Genus Ptychochromis (Teleostei: Cichlidae), with the Description of Five New Species and a Diagnosis for Katria, New Genus.''

Ptychochromis Onilahy
''Ptychochromis onilahy'' is a species of cichlid endemic to the Onilahy River in southwestern Madagascar. Despite several recent visits to the region, this species has not been recorded since 1962 when the only known five specimens were collected. It is listed as extinct by the IUCN (their initial rating was made before its official description, and therefore listed under the temporary name ''Ptychochromis sp. nov. 'Kotro), but the Onilahy River system is large, and there is a small chance remnant populations exist in remote regions.Stiassny, M., and Sparks, J. S. (2006).

Ptychochromis Ernestmagnusi
''Ptychochromis ernestmagnusi'' is a species of fish cichlid only known from the Mananara du Nord River in northeastern Madagascar, but it is probably more widespread in that region.Sparks, J. S., and Stiassny, M. (2010). ''A new species of Ptychochromis from northeastern Madagascar (Teleostei: Cichlidae), with an updated phylogeny and revised diagnosis for the genus.'' Zootaxa 2341: 33–51. If so, it likely occurs in the Mananara-Nord Biosphere Reserve (near the town Mananara Nord), which would give it a level of protection. It can reach in standard length. The specific name honours Ernest Magnus (1908-1983) who was the uncle of the German-American marine biologist and ichthyologist Rudolf Arndt who gave generous support to the author's research, at the request of Anrdt's family, whose “generous gift” supported the authors’ research.

Cichlid Genera
Cichlids are fish from the family Cichlidae in the order Cichliformes. Cichlids were traditionally classed in a suborder, the Labroidei, along with the wrasses ( Labridae), in the order Perciformes, but molecular studies have contradicted this grouping. The closest living relative of cichlids is probably the convict blenny, and both families are classified in the 5th edition of ''Fishes of the World'' as the two families in the Cichliformes, part of the subseries Ovalentaria. This family is both large and diverse. At least 1,650 species have been scientifically described, making it one of the largest vertebrate families. New species are discovered annually, and many species remain undescribed. The actual number of species is therefore unknown, with estimates varying between 2,000 and 3,000. Many cichlids, particularly tilapia, are important food fishes, while others, such as the ''Cichla'' species, are valued game fish. The family also includes many popular freshwater aquar ...
