Nothobranchius is a genus of small, freshwater annual fish. It has been alternatively classified in the family Nothobranchiidae or a more inclusive Aplocheilidae. The species are mainly found in East Africa from Sudan to northern South Africa, but half a dozen species are found in the upper Congo River Basin and two species are from west-central Africa. The greatest species richness is in Tanzania. Many species have very small distributions. There are many species: as of 2018 there are more than 70 species.
Nothobranchius jubbi is a species of killifish in the family Nothobranchiidae. It occurs in north eastern Africa in Kenya, Somalia and Ethiopia in temporary pools, ditches, marshes and rain pans, normally ones without any connections to rivers. This species was described in 1979 by Rudolf Hans Wildekamp and Heinz Otto Berkenkamp with the type locality given as a pool on the road to Garsen, 17 miles north of Malindi. The specific name honours the South African meteorologist and ichthyologist Reginald A. “Rex” Jubb (1905-1987) of the Freshwater Fish Section at the Albany Museum in Grahamstown, South Africa, in recognition of his taxonomic work on the genus Nothobranchius.
The blue notho, or Patrizi's notho is a species of killifish in the family Nothobranchiidae. It is found in Kenya, Somalia and Ethiopia. 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.
Blue lyretail, also known as steel-blue aphyosemion and Gardner's killi. It is a species of killifish from Nigeria and Cameroon.
Rivulus is a genus of small freshwater fish in the Aplocheilidae family of Cyprinodontiformes. It was traditionally considered to be the largest genus in its family; however, the genus's size is currently in dispute. Wilson J. E. Costa split this genus into several new genera in 2004 and 2011, leaving only a few Greater Antillean species in Rivulus itself. Despite being moved to other genera, some of the species retain the common name "rivulus", like the well-known mangrove rivulus. Shortly after the review by Costa, another review authored by J.H. Huber refuted the split, moving the proposed genera back in Rivulus and again making the genus the largest in the family Aplocheilidae.
Nothobranchiidae are a family of bony fishes containing roughly 300 species, also known as African rivulines. They are small killifish, usually measuring about 5 centimetres (2.0 in). They are limited to Africa, living in fresh water but being also somewhat salt-tolerant. They are also found in muddy or brackish water. Some species are kept as aquarium pets. They have frilly fins and many are brightly colored. They were formerly included in the family Aplocheilidae ; a return to that broader family has recently been suggested.
Fundulopanchax is a genus of killifish living in near-coastal fresh water streams and lakes in Western Africa. All species were previously biologically classified as members of the genus Aphyosemion, with the exception of Fundulopanchax avichang, F. gresensi and F. kamdemi, which were all scientifically described after the major revision of the Aphyosemion complex.
Aphyosemion is a genus of African rivulines endemic as the name indicates to Africa. Many of these species are popular aquarium fish.
Callopanchax is a genus of African rivulines endemic, as the name indicates, to Africa. Some of these species are popular aquarium fish.
Epiplatys is a genus of African rivuline in the family Nothobranchiidae endemic to Africa as the name indicates. Several of these species are popular aquarium fish.
Fenerbahce is a genus of fish in the family Nothobranchiidae endemic to Africa where they are only known from the Congo Basin. The current genus name was adopted to replace the genus AdamasHuber, 1979 which was a junior homonym of the genus AdamasMalaise, 1945 of the sawfly family Tenthredinidae.
Nimbapanchax is a genus of African rivulines, fish endemic to freshwaters in tropical West Africa.
Pronothobranchius kiyawensis is a species of killifish from the family Nothobranchiidae which is native to western Africa where it occurs in the drainage basin of Lake Chad. This species grows to a length of 4.5 centimetres (1.8 in) TL. This species is found in the aquarium trade.
Pronothobranchius is a genus of aplocheilid fish native to western Africa.
Micropanchax is a genus of poeciliids native to Africa.
Anablepsoides is a genus of killifish in the family Rivulidae native to tropical South America and the Lesser Antilles. The majority are from the Amazon and Orinoco basins, as well as freshwater systems in the Guiana Shield, but a few species are from northern Venezuela, northeastern Brazil and the Lesser Antilles. Although largely restricted to lowlands, a few species occur in the lower East Andean foothills. They are mostly found in shallow fresh water swamps, streams, edges of rivers, ponds and pools, but a few may occur in brackish estuaries. They are able to jump over land and breathe air for short periods, allowing them to access isolated waters inhabited by few or no other fish. Several Anablepsoides species have small distributions and some are seriously threatened by habitat loss; the entire known range of A. xinguensis is in the area flooded by the Belo Monte Dam.
Atlantirivulus is a genus of fishes in the family Aplocheilidae. They are endemic to shallow swamps, creeks, streams and pools in the Atlantic Forest in southeastern Brazil, ranging from Rio de Janeiro to Santa Catarina. Several of the species are highly threatened, while others survive in well-protected reserves. A. janeiroensis was initially feared extinct, but has since been rediscovered in two reserves.
Cynodonichthys is a genus of freshwater killifish in the family Aplocheilidae. They are found in Middle America, ranging from southern Mexico, through Central America, to Colombia. They are non-annual killifish and inhabit small forest streams from the lowlands to an altitude of 1,500 m (4,900 ft).
Yssolebias martae is a species of fish in the family Cyprinodontidae only known from the Río Magdalena near Santa Marta, Colombia. This species is poorly known and may possibly be extinct with only one specimen known. Long of questioned validity and uncertain generic attribution, in 2012 J. H. Huber erected the genus Yssolebias to contain this enigmatic species. This species is the only known member of its genus. This species is placed in the tribe Yssolebiini.
Nothobranchius lucius is a species of killifish, an African rivuline which is placed in the family Nothobranchiidae. It is endemic to Tanzania.
