From the south of the Sahare located river basins of the Senegal-, Gambia-, Niger-, Volta River and the White Nile origins Brienomyrus niger. There they inhabit densly vegetated zones and migrate during the spawning season onto the floodplains. They are able to orient themselves by their electrical receptors. As all mormyrids they own electrical organs which allow them to comunicate with conspecifics. Since their electrical impulse pattern are typical for the species, it can be used for their classification. Due to their small size and trouble-free maintenance there are numerous neurophysiological scientific investigations present. In the wild they feed on water insects and their larvae, in tanks they can be fed with different commercial products, but frozen food would be the best.
