Mormyrus rume Mormyrus rume

Mormyrus rume is native to freshwater systems in West Africa. Mormyrids are also called elephant-nosed fish, and sometimes trunkfish (although that is also a name for some species of marine boxfish), along with others in different genera in the same family.

It can grow to 1 metre long and is common as human food in its native range. Mainly nocturnal and living near the substrate, it eats insects and larvae. It navigates surroundings using electro receptors and presumably feels safe and invisible in a transparent pipe. It can give a mild electric shock for defence.
