Actinopterygii (ray-finned fishes) > Cyprinodontiformes
(Rivulines, killifishes and live bearers) > Nothobranchiidae
Etymology: Nothobranchius: Greek, nothos = false + Greek, brangchia = gill (Ref. 45335). More on author: Hilgendorf.
Environment: milieu / climate zone / depth range / distribution range
Freshwater; benthopelagic; pH range: 8.2 - ? ; dH range: 6 - ?; non-migratory. Tropical; 18°C - 24°C (Ref. 2059)
Africa: Wembere, Bubu, Malagarasi, Lake Rukwa and Lake Victoria drainages in Tanzania (Ref. 59344). Introduced for mosquito control in several localities in Uganda, Kenya, Tanzania and probably Zambia (Ref. 3788, 59344, 106076).
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 5.5 cm TL male/unsexed; (Ref. 27139)
soft rays: 16 - 18. Distinguished from all other species of the genus by having a very dark to almost black scale margins in males, unique male fin coloration (a light band in the anal and caudal fins, before a wide black margin); markings are absent in females (Ref. 26713).
Seasonal fish with very short life span, typical species of steppe and savannah which need long dry season (Ref. 27292). Occurs in swamps and restwater pools of river floodplains (Ref. 79882), in ditches and despressions in floodplains (Ref. 59344). Bottom spawner (Ref. 79882). Incubation of eggs in captivity is 3-6 months and young fish reach maturity in 6-7 weeks (Ref. 59344). Specimens from central Tanzania to various localities in Tanzania, Uganda, Kenya and other countries, for mosquito control (Ref. 59344).
