The striped nothobranch (''Nothobranchius taeniopygus'') is species of freshwater fish of East Africa, belonging to the family Nothobranchiidae. The maximum recorded total length of the striped notobranch is . Males are readily recognised by their bold blackish scale rims, and anal and caudal fins which have a black margin ith a lighter band below; such a colour pattern is not found in other ''Nothobranchius''. Females are nondescript and resemble those of congeners. The anal and dorsal fins of the striped nothobranch have no spines, but, respectively, 16-18 and 11-17 soft rays.〔FishBase ()〕 ==Range and ecology== ''N. taeniopygus'' is found in central Tanzania and southern Uganda, and perhaps southwestern Kenya. It has been introduced to other places in its native countries, and probably also Zambia. Earlier it was believed to occur in Burundi also, but this is at least doubtful. This killifish's native range are the drainage basins of Lake Kyoga and Victoria, and the Aswa, Bubu and Malagarasi River.〔 Its natural habitats are rivers, swamps, freshwater lakes and marshes, temporary pools, floodplains and inland deltas. It can inhabit fairly cool (for its tropical range) water, with a temperature of , but of course it must be very eurythermic as the small pools and puddles it usually inhabits will heat up rapidly during the day and cool down just as rapidly in the night. The pH in its habitat has been measured at 8.2 (somewhat alkaline) and the water hardness at 6° dH (rather soft), but this may not be indicative of its preferences and tolerance as very little data exists. A small carnivore, it feeds on aquatic invertebrates, mainly insect larvae and crustaceans. Like its relatives it is semelparous and spawns in the dry season. The eggs are deposited in the substrate, and the parents then die, as the small waterbodies which they inhabit would mostly dry up anyway. The eggs are adapted to surviving the drying-up in diapause, and can even be entirely outside the water for a time, as long as the substrate is still moist. They hatch after 3–5 months.〔 It is not considered a threatened species by the IUCN. Locally, populations may disappear after habitat destruction and water pollution by agriculture. On the other hand, it is very widespread and resilient, and to some degree used for mosquito control in and around its native range. It is sometimes found as an aquarium fish, but unlike some other ''Nothobranchius'', it is difficult to keep as its requirements are still insufficiently known. 〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Striped nothobranch」の詳細全文を読む スポンサード リンク
