Janpapi is a member of the subgenus aphyobranchius, which are small, delicate, surface dwelling Nothobranchius
Like other Nothobranchius, this species is best spawned over peat moss, and prefers a diet of livefoods - though free-swimming livefoods are preferred to foods that typically sink: for example newly hatched Artemia and mosquito larvae. Newly hatched fry are typically too small for brine shrimp, and should be fed paramoecium as a first food.
