 The non-cichlid native fish include African tetras ("Brycinus"), cyprinids ("Enteromius", "Garra", "Labeo", "Labeobarbus", "Rastrineobola" and "Xenobarbus"), airbreathing catfish ("Clariallabes", "Clarias" and "Xenoclarias"), bagrid catfish ("Bagrus"), loach catfish ("Amphilius" and "Zaireichthys"), silver butter catfish ("Schilbe intermedius"), "Synodontis" squeaker catfish, "Nothobranchius" killifish, poeciliids ("Aplocheilichthys" and "Micropanchax"), the spiny eel "Mastacembelus frenatus", elephantfish ("Gnathonemus", "Hippopotamyrus", "Marcusenius", "Mormyrus", "Petrocephalus", and "Pollimyrus"), the climbing gourami "Ctenopoma muriei" and marbled lungfish ("Protopterus aethiopicus").At a genus level, most of these are widespread in Africa, but the very rare "Xenobarbus" and "Xenoclarias" are endemic to the lake, and the common "Rastrineobola" is near-endemic.Four species of freshwater crabs are known from Lake Victoria
