Nothobranchius is a genus of small, freshwater killifish, classified in the family Nothobranchiidae in the order Cyprinodontiformes. There are about a hundred species in the genus, many with very small distributions. They are primarily native to East Africa from Sudan to northern South Africa, whereas a dozen species are found in the upper Congo River Basin; the greatest species richness is in Tanzania.

Nothobranchius neumanni is a species of killifish in the family Nothobranchiidae. It is endemic to Tanzania. It occurs in both perennial and seasonal wetlands including rivers, lakes and ponds where it most likely feeds on planktonic crustaceans.

Nothobranchius ditte is a species of brightly colored seasonal killifish in the family Nothobranchiidae, belonging to the Nothobranchius brieni species complex. It is endemic to freshwater habitats in the south-eastern parts of the Democratic Republic of the Congo. Adult males reach a length of about 40–42 mm, but the females are slightly smaller. The species is a semi-annual killifish. They inhabit ephemeral pools filled by rainwater during the monsoon season, being adapted to the alteration of dry and wet seasons. As with all members of the genus Nothobranchius, they show extreme life-history adaptations: their embryos survive by entering a three or four month long diapause, within eggs that have a very hard chorion and are resistant to desiccation and hypoxia. When the habitats dry up, the adult fish die and the eggs survive encased in the clay during the dry season.
Nothobranchius sainthousei is a species of brightly red- and blue colored seasonal killifish in the family Nothobranchiidae. It is endemic to freshwater habitats in the Chembe district of the Luapula Province in northern Zambia. It was named in honour of Ian Sainthouse, a "renowned breeder and collector of killifish, for his special longstanding dedication to researches on the genus Nothobranchius".
