Bedotia is a genus of the family Bedotiidae of fishes endemic to Madagascar.
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.

It was described by Charles Tate Regan in 1903 with Madagascar given as the type locality, Regan deposited the type in the Muséum d'histoire naturelle de Genève and named the genus in honour of its director Maurice Bedot (1859-1927).

Ptychochromoides vondrozo is a critically endangered species of cichlid endemic to the Mananara-sud river and its tributaries near Vondrozo in southeastern Madagascar. These are deep and moderate to fast-flowing. Its entire range covers less than 100 square kilometres (39 sq mi), which makes it highly threatened from continued sedimentation caused by deforestation. It is also threatened by other species that have been introduced to the region. It reaches a length of 20.4 centimetres (8.0 in) SL.

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).

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. If so, it likely occurs in the Mananara-Nord Biosphere Reserve, which would give it a level of protection. It can reach 14.7 cm (5.8 in) 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. Magnus played an important part in assisting the Arndt family to survive in Berlin after the Second World War and then emigrate to New York City in 1950, by giving them "food, clothing, shelter, love, many kindnesses and moral support".
