Freshwater fish of Madagascar

The red-tailed silverside, or zona (Bedotia geayi) is a species of Madagascar rainbowfish endemic to the Mananjary River drainage in Madagascar. Zona are threatened by both habitat loss and introduced species. It has often been confused with the related B. madagascariensis, which is common in the aquarium trade. In addition to meristics, the two species can be separated by the exact colour pattern on their tail fin (males of both typically have red in the tail) and the distinct red spot on the lower jaw of breeding male B. geayi (lacking in B. madagascariensis). B. geayi was described in 1907

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.

Katria is a genus of freshwater fish in the cichlid family. It contains the single species Katria katria, a vulnerable species from the Mangoro and Nosivolo Rivers in east-central Madagascar, that was formerly included in the genus Ptychochromoides. The only other monotypic cichlid genus in Madagascar is Oxylapia, and it is restricted to the same region as Katria. In 2010, the Nosivolo River was designated as a Ramsar Site. The Katria reaches about in length.

The kotsovato (Paretroplus kieneri) is a species of cichlid from northwestern Madagascar. As presently defined its range spans several river basins, but this could possibly include more than one species. It is threatened by habitat loss and competition from introduced species. This relatively elongate Paretroplus reaches about in length and is closely related to P. gymnopreopercularis, which it resembles. The specific name honours the French fisheries scientist André Kiener.

The katrana (Rheocles alaotrensis) is a species of fish in the Bedotiidae family. It is endemic to the basin of Lake Alaotra in Madagascar. Its natural habitats are rivers and freshwater lakes. It is threatened by habitat loss. This species was described by Jacques Pellegrin as Atherina alaotrensis with the type locality of Lake Aloatra.

The kotso (Paretroplus petiti) is a species of cichlid fish from northwestern Madagascar. Currently rated as data deficient by the IUCN, this species is virtually unknown. The only known specimen is a juvenile that was collected more than 80 years ago. It is not entirely clear where it was collected, but likely from the Maintimaso River or Lake Ambanja, which both are part of the Betsiboka River drainage. Erroneously, the name P. petiti has often been applied to members of a different species, P. dambabe. The specific name honours the French zoologist and anatomist Georges Petit (1892-1973) of

The Ptychochrominae are a subfamily in the cichlid family of fish. It includes about 14 species. They are restricted to lakes and rivers in Madagascar, and the majority are threatened. Most cichlid genera native to Madagascar are included in this subfamily; the only exceptions are Paretroplus (subfamily Etroplinae) and Paratilapia (sometimes included in the Ptychochrominae, but likely belongs in its own subfamily).
