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.

Loiselle in 2006 with the type locality given as "Swamp draining into tributary stream of Ikopa River, flowing parallel to RN-4 at Antanimbray village, 17°10'79"S, 46°50'97"E, Betsiboka River drainage, Madagascar, elevation 246 meters".
The kotso 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 Muséum national d’Histoire naturelle, who collected type.
Phallostethus dunckeri is a species of fish in the family Phallostethidae. It is endemic to Malaysia.
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).
Rheocles sikorae is a species of rainbowfish in the subfamily Bedotiinae, the Madagascar rainbowfishes. It is endemic to Madagascar where found in tropical rivers and streams. It can reach the maximum recorded length of 11.5 cm (4.5 in).

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".
Teramulus kieneri, the Keiner's silverside or vily, is a species of silverside endemic to Madagascar where it is found in rivers around on the eastern coast. This species was described by J.L.B. Smith in 1965 with the type locality given as the coastal swamps near Tamatave. It has since been found in other areas of the island, including the basin of the Nosivolo River and in the Bemarivo River. Smith gave this species the specific name keineri to honour the French fisheries scientist, André Kiener, who assisted in the collection of the type in 1961, although it was initially reported as Atherinomorus duodecimalis. It is the type species of the genus Teramulus.
Teramulus waterloti is a species of silverside from the subfamily Atherinomorinae which is endemic to Madagascar. This species occurs in rivers, creeks, and streams in north western Madagascar from the Mananjeba River south to the Anjingo River. The IUCN classify this species as Endangered and it is threatened by deforestation which degrades its habitat through sedimentation and by the introduction of invasive fish species such as Channa maculata. This fish was described in 1932 as the subspecies waterloti of Atherina duodecimalis by Jacques Pellegrin who named it after Georges Waterlot (1877-1939), a collector of specimens in Africa and Madagascar for Muséum national d'histoire naturelle, including the type of this species, which he collected from Antikotazo Creek, District d'Ambilobé, Diégo Suarez Province.
Typhleotris pauliani is a critically endangered species of fish in the family Milyeringidae that is endemic to Madagascar, where it is only known from a few caves and sinkholes in the southwestern portion of the island.

Pachypanchax patriciae is a species of killifish from the family Aplocheilidae. It is endemic to Madagascar where it occurs in the basins of the Mananjeba, Mahavavy du Nord, Ifasy, Manehoko, and Ampandra rivers in the north west of the island. The specific name of this fish honours the Malagasy conservationist Patricia Yazgi (1946-2006), who ran the charity Friends of Fishes and who supported efforts to document and conserve the freshwater fish fauna of Madagascar. This species appears to feed mainly the adults and nymphs of terrestrial insects and on the larvae of aquatic insects and its most important predators are fish-eating birds and dragonfly nymphs. It may, however, be threatened by introduced alien fishes in some areas.
