It occurs in both perennial and seasonal wetlands including rivers, lakes and ponds where it most likely feeds on planktonic crustaceans. This species was described as Fundulus neumanni by Franz Hilgendorf in 1905. The specific name honours Hilgendorf's companion on some of his expeditions to Africa, the German ornithologist Oscar Neumann (1867-1946).
The spotted killifish is a small, short lived species of fish, an African rivuline from the family Nothobranchiidae. These fish are native to many isolated freshwater pools located in the savannah depressions of east Africa, specifically Malawi, Mozambique, Zimbabwe, and South Africa. This species of fish occurs in ephemeral waters and killifish eggs can survive long periods of dehydration. The word killifish likely comes from the Dutch kil for kill.
The blue notho, or Patrizi's notho is a species of killifish in the family Nothobranchiidae. It is found in Kenya and Somalia. Its natural habitat is running water. The males are usually around 5.0 centimetres (2.0 in). In the aquarium the females lay their eggs on bottom peat. This species was described as Fundulus patrizii by Decio Vinciguerra in 1927 with a type locality of the Harenaga swamps, near mouth of the Juba River in southern Somalia. Vinciguerra gave this fish the specific name of patrizii in honour of the collector of the type Saverio Patrizi Naro Montoro (1902-1957), an Italian explorer, zoologist and speleologist.
Nothobranchius steinforti is a species of killifish in the family Nothobranchiidae. It is endemic to Upper Wami River drainage, Tanzania. Its natural habitat is intermittent freshwater marshes, pools and rice fields. This species was described in 1977 by Rudolf Hans Wildekamp with the type locality given as "8 kilometers from Kimamba, Tanzania". The specific name honours the Dutch aquarist Theo Steinfort who helped collect the type and bred this species in captivity, making it available to other killifish hobbyists.
The Mnanzini nothobranch is a species of killifish in the family Nothobranchiidae. It is endemic to Kenya where it occurs on the floodplains of the lower Tana River system where it is found in temporary waterbodies and connecting streams.

The Mexican rivulus is a species of killifish from the family Rivulidae which is endemic to Mexico where it is found in the Papaloapan and Coatzacoalcos River basins. This annual killifish grows to a total length of 4 cm (1.6 in). It is the only known species in its genus, but its exact taxonomic position remains uncertain, as it has not been included in any phylogenetic study.

The emerald aphyosemion is a species of killifish, endemic to the lower Cross River basin in Nigeria. It is a coastal rainforest fish which lives in small streams and ponds. It prefers a temperature of around 75 °F (24 °C), and a slightly acidic pH around 6–7. The specific name honours the Danish count, army colonel, explorer and ichthyologist Jørgen J. Scheel (1916–1989).
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.
Nannopetersius ansorgii is a species of African tetra fish. It is found in the central Africa in the Benito (Mbini), Chiloango, Kouilou, Loeme and Ogooué rivers of Gabon and Equatorial Guinea and the Bengo and Congo River basins of Angola and Democratic Republic of the Congo.
