Nothobranchius lucius is a species of killifish, an African rivuline which is placed in the family Nothobranchiidae. It is endemic to Tanzania.
Nothobranchius lucius is a relatively large species of killifish and can be distinguished from the closely related N. melanospilus and N. makondorum , by its comparatively longer head, with a longer snout apparent in both males and females with the males having a thinner body. The snout is pointed with a subterminal mouth which faces slightly upwards. The dorsal profile is slightly concave on head and also concave from the nape to the posterior end of the dorsal fin; the caudal peduncle has a straight profile both dorsally and ventrally. [1] Compared to many species in the genus Nothobranchius , N. lucius is rather dull in colour although an identifying mark is the presence of an orange line before the black margin of the caudal fin. [2]
Nothobranchius lucius is found in a small area in southern central Tanzania, between Ifakara and the Kilombero river ferry. It appears to be replaced by the similar N. melanospilus to the east and by N. makondorum to the south of its range. [2]
Nothobranchius lucius is found in seasonal pools and marshes where it reproduces in the wet season and the eggs enter diapause to hatch the following season. [1] It is a predatory species and swallows smaller fishes whole. [2]
Nothobranchius lucius was described in 2009 by Rudolf Hans Wildekamp, Konstantin Mikhailovich Shidlovskiy and Brian R. Watters with the type locality given as being a large pool on west side of road between Ifakara and the Kilombero River ferry, two kilometres south of Ifakara and one kilometre north of Kilombero River. [3] The specific name lucius is Latin for a pike, a reference to this species strong teeth, predatory habits and somewhat pike-like appearance. [4]
This species is known in the aquarium trade where it is often known as the pike nothobranch and was called N. sp aff melanospilis before its formal description in 2009. [2]
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.
The orchid nothobranch is a species of killifish in the family Nothobranchiidae. It is endemic to the lower basin of the Rufiji River in Tanzania. Its natural habitat is temporary pools and swamps. This species is found in both a blue and red form. This species was described in 1982 by Lothar Seegers with the type biology given as the Rufiji River near Utete, eastern Tanzania. The specific name honours Seegers companion on two expeditions, the German aquarist Gerd Eggers.
Nothobranchius foerschi is a species of killifish in the family Nothobranchiidae. It is endemic to Tanzania. Its natural habitat is probably temporary pools.

The redtail notho is a species of killifish in the family Nothobranchiidae. It is endemic to Zanzibar. Its natural habitats are intermittent rivers and intermittent freshwater marshes. The redtail notho eats mosquito larvae and other planktonic creatures. Scientists are looking at introducing the species elsewhere in Africa to help with malaria prevention.
Nothobranchius janpapi is a species of killifish in the family Nothobranchiidae. It is endemic to the Ruvu and Rufiji rivers in eastern Tanzania. Its natural habitats are small pools and ponds situated on floodplains. The specific name honours the Dutch aquarist Jan Pap, who first discovered this species in 1975 and sent examples back to the Netherlands.
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 kirki, the redfin notho, is a species of killifish from the family Nothobranchiidae which is endemic to Malawi where it occurs in the drainages of Lake Malawi and Lake Chilwa. It inhabits swamps and ephemeral pools. This species can reach a length of 5 centimetres (2.0 in) TL. It can also be found in the aquarium trade. This species was described in 1969 by the South African ichthyologist Rex Jubb from types collected by R. G. Kirk, who was a fish biologist of the Agricultural Research Services part of the Ministry of Natural Resources of Malawi, from a pool adjacent to the Likangala River which forms part of the endorheic basin of Lake Chilwa in Malawi.
Nothobranchius korthausae is a species of killifish in the family Nothobranchiidae. It is endemic to Mafia Island in Tanzania. Its natural habitat is pools, ditches and small streams. The specific name of this species honours the German aquarist Edith Korthaus who collected the type.
Nothobranchius luekei is a species of killifish in the family Nothobranchiidae. It is endemic to Tanzania. Its natural habitat is temporary pools. Its specific name honours the German aquarist Karl Heinz Lüke who was the first person to breed this species in an aquarium.
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 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.
Nothobranchius palmqvisti is a species of killifish in the family Nothobranchiidae. It is found in Kenya and Tanzania. Its natural habitats are swamps and intermittent freshwater marshes. This species was described as Fundulus palmqvisti by Einar Lönnberg in 1907 with the type locality being Tanga in the Usambara Mountains of north eastern Tanzania, the type being collected on the 1905-06 Sjöstedts Kilimandjaro-Meru Expedition. The specific name honours the patron of that expedition, Gustaf Palmqvist.
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 rachovii, or the bluefin notho, is a species of freshwater annual killifish from Mozambique. It can grow up to 6 cm (2.4"). It is popular among killifish enthusiasts, who raise them from eggs in aquaria.
Nothobranchius ditte is a species of brightly colored fish 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 brieni is a species of brightly colored fish in the family Nothobranchiidae. It is endemic to freshwater habitats in the south-eastern parts of the Democratic Republic of the Congo.
Nothobranchius sainthousei is a species of brightly red- and blue colored fish in the family Nothobranchiidae. It is endemic to freshwater habitats in the Chembe- and Milengi districts 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".
