Rainbowfishes are small, colourful freshwater fishes belonging to the family Melanotaeniidae, found in northern and eastern Australia, New Guinea, Sulawesi and Madagascar.
Bedotiinae are a subfamily of the rainbowfish family Melanotaeniidae, commonly known as the Madagascar rainbowfish, Madagascan rainbowfish, or Malagasy rainbowfish due to their endemism to Madagascar. It includes two genera, Bedotia and Rheocles.
Rheocles is a genus of Madagascar rainbowfish. Rheocles has a restricted distribution, being found only in certain forested freshwater habitats in the central and eastern highlands of Madagascar including the Nosivolo River. The genus appears to feed almost exclusively on allochthonous material, primarily insects falling onto the water surface.
The red-tailed silverside, or zona is a species of Madagascar rainbowfish endemic to the Mananjary River drainage in Madagascar. It is threatened by 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 can be separated by the exact colour pattern on their tail fin and the distinct red spot on the lower jaw of breeding male B. geayi. B. geayi was described in 1907 by Jacques Pellegrin from a type collected by the pharmacist and natural history collector Martin François Geay (1859-1910), who Pellegrin honoured with its specific name.
Bedotia longianalis is a species of Madagascar rainbowfish endemic to Madagascar. Its natural habitat is the lower reaches of rivers and its range extends from the Ifontsy to the Anove rivers and it is also found on Île Sainte-Marie, in north-eastern Madagascar. It was described in 1914 by Jacques Pellegrin from a type collected from a market in Mahambo.
Bedotia masoala is a species of rainbowfish in the subfamily Bedotiinae. It is endemic to Madagascar. Its natural habitat is rivers. It is threatened by habitat loss. This species was described in 2001 by John S. Sparks from a type locality of the Ankavanana River on the Masoala Peninsula in Antalaha District.
Bedotia alveyi, the Makira rainbowfish, is a species of Madagascar rainbowfish from rivers and streams in the Makira region of Madagascar where it occurs in the tributaries of the Antainambalana and Vohimaro rivers. This species was described in 2010 by Christopher C. Jones, Leo Smith and John S. Sparks from types collected from a small stream north of Ambodivoankongy, in a tributary of the Antainambalana River in Toamasina Province. The specific name honours Mark Alvey of the Field Museum in Chicago.
Bedotia albomarginata is a species of Madagascar rainbowfish from the Mananara and Reinana river basins in Madagascar. It is threatened by habitat loss. This species was described by John Sparks and Leila Rush in 2005 from types collected near the towns of Vondrozo and Vevembe from the Sahapindra River, which is a tributary of the Mananara River, in Fianarantsoa Province.
Bedotia tricolor is a species of Madagascar rainbowfish endemic to Madagascar. Its natural habitat is rivers. It is threatened by habitat loss. This species was described by Jacques Pellegrin in 1932 with the type locality given as a tributary of the Faraony River in the area of Manakara.

Ptychochromis loisellei is a species of cichlid from the Mahanara River basin north of Sambava in northeastern Madagascar. It remains common within its small range, but it is threatened by habitat loss and introduced species. It reaches about 11.9 centimetres (4.7 in). The similar named Paretroplus loisellei is also restricted to the Mahanara River basin. The specific name honours Paul V. Loiselle, Emeritus Curator of Freshwater Fishes at the New York Aquarium and a researcher in, and campaigner for the conservation of, the freshwater fish of Madagascar.
The katrana 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.
Rheocles derhami is a species of rainbowfish in the subfamily Bedotiinae, the Madagascar rainbowfishes. It is endemic to the Ambalona River and Mangarahar River in Madagascar. Its natural habitat is rivers. It was described by Melanie Stiassny and Damaris Rodriguez in 1992 and was named in honour of the Swiss conservationist Patrick De Rham.

Rheocles pellegrini is a species of rainbowfish from the subfamily Bedotiinae. It is endemic to Madagascar. Its natural habitat is rivers. This species was described by John Treadwell Nichols and Francesca Raimonde La Monte in 1931 from a type collected "one day west of Andapa." by Austin L. Rand and P. A. DuMont who were part of the "Archbold Expedition" to Madagascar of 1929–1931. R. pellegrini was not then recorded until the 21st century when populations were found in the area of the type locality. The specific name honours the French ichthyologist Jacques Pellegrin (1873–1944).

It is threatened by habitat loss. It was described by Melanie Stiassny in 1990 from a type locality given as "Sandrangato River, south of Moramanga".
Paretroplus loisellei is a vulnerable species of cichlid fish from the Mahanara River basin north of Sambava in northeastern Madagascar. Until its scientific description in 2011, this population was usually referred to as Paretroplus sp. nov. "Ventitry" or included in P. damii, which it resembles. It reaches about 15 centimetres (5.9 in) in length, and is threatened by habitat loss and introduced species. The similar named Ptychochromis loisellei is also restricted to the Mahanara River basin.
