Peters Elephant Nose Fish (Gnathonemus petersii)


One of the most unusual of the Mormyrids (a family of weakly electric fish found primarily in Africa), Peter’s Elephant Nose is found throughout much of Western and Central Africa, where it inhabits slow moving, shallow waters usually over muddy or sandy substrate. Their namesake snout is used to root through substrate to find small prey items. In the aquarium, they can be a somewhat finicky eater at first, but will usually accept frozen bloodworms, mysis, and other similar foods. Ideally, these fish should be kept singly as more than one Elephant Nose in the same tank are likely to fight. They should also be kept with peaceful tankmates to avoid bullying or the fish being outcompeted for food.
