The Blunt-jawed Elephantnose (Gnathonemus tamandu), is an elephantfish in the genus Gnathonemus. It is also known by the name Worm-jawed Mormyrid. It is found in murky waters in West Africa. The fish is brown or black with a long elephant-like snout and the mouth is located near the end of this proboscis. Its diet consist of worms, small fish, and insects. In captivity they are fairly hard to care for because they need a narrow range of water temperatures, a large tank, and special food....
