Nothobranchius is a genus of small, freshwater killifish, classified in either the family Nothobranchiidae or a more inclusive Aplocheilidae in the order Cyprinodontiformes. There are many species: as of 2018 there are more than 70 species, many with very small distributions. They are primarily native to 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.
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.
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. 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 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 blue lyretail, also known as steel-blue aphyosemion and Gardner's killi. It is a species of killifish from Nigeria and Cameroon.
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.
Floridichthys is a genus of pupfishes native to the southeastern United States, Mexico and northern Central America. The name of this genus is a compound of Florida and the Greek for "fish", ichthys. The ichthyologist Carl Leavitt Hubbs thought that the genus was confined to Florida at the time he coined the name.
Aphyosemion is a genus of African rivulines endemic as the name indicates to Africa. Many 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.
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. This species was described by Robert Rush Miller and Carl Leavitt Hubbs as Rivulus robustus in 1974, it was reclassified in the monotypic genus Millerichthys in 1995, the generic name honouring Robert Rush Miller.
Rachovia is a genus of killifish from the family Rivulidae the species of which are endemic to the Orinoco, Maracaibo and Magdalena basins in Colombia and Venezuela, where they live in small temporary waters like ponds. They are small annual killifish that reach up to 6 cm (2.4 in) in total length. The name of this genus honours the German aquarist Arthur Rachow (1884-1960) who sent fish specimens to George S. Myers.
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).
Aphyosemion bivittatum is a species of freshwater fish belonging to the family Aplocheilidae. It is found in rivers in southeastern Nigeria and southwestern Cameroon. It was originally described as Fundulus bivittatus by Swedish zoologist Einar Lönnberg in 1895. The holotype was discovered near a waterfall in the Ndian River in Cameroon and currently is located in the Stockholm Museum.
The spotfin killifish is a member of the genus Fundulus. This hardy fish is notable for spending its entire life in sporadically flooded salt marsh habitat, sheltering in shallow pools, puddles, and small tidal rivulets. It closely resembles the mummichog in shape and coloration, but the two species can be distinguished by dorsal fin ray count: 8–9 in the spotfin versus 11–12 in the mummichog. Additionally, the dorsal fin of F. luciae originates farther back, and slightly behind the anal fin origin; in the mummichog, the dorsal fin begins anteriorly to the anal fin origin. The spotfin killifish is named for the pronounced ocellus found on the posterior dorsal fin of adult males. It is a small fish, seldom attaining 50 mm in total length. Its distribution extends along the U.S. east coast from Massachusetts to Georgia.
The Seminole killifish is a fish of the genus Fundulus, endemic to the U.S. state of Florida.
Jørgen Jacob Scheel was a Danish aristocrat, soldier, explorer and ichthyologist. His father was Jørgen Carl Scheel (1874-1944) and his mother was Erikka Ellen Estrup (1891-1960); his parents married in 1912. He was baptized in the Marie Magdalene Church in Sønderhald. Scheel was a landgrave of the Danish aristocracy.
Nothobranchius lucius is a species of killifish, an African rivuline which is placed in the family Nothobranchiidae. It is endemic to Tanzania.
The Nile killifish, also known as the Nile lampeye, is a species of killifish from the family Poeciliidae. It is found in the White Nile drainage in Sudan, the Nile Delta in Egypt, the Wembere and Malagarasi Rivers in Tanzania and in the Lake Victoria basin in Uganda and Tanzania. However, it is thought to have been extirpated from Egypt, the introduction of alien poecilid fish, agricultural pollution and increasing salinity are all thought to have contributed to its local extinction in the Nile Delta.
Fundulopanchax sjostedti, the blue gularis, golden pheasant gularis or red aphyosemion, is a species of toothcarp endemic to the Niger delta. It is only found in Nigeria and Cameroon. It is named after the Swedish naturalist Bror Yngve Sjöstedt (1866–1948) who collected the type specimen close to a waterfall by the Ndian River, in the Ndian department in Cameroon's Southwest Region.
