Elephant Nose Fish - Gnathonemus petersii

The Elephantnose Fish, Gnathonemus petersii, is an African freshwater fish with an elongated lower lip used to find food in the substrate. Its dark body and unusual profile make it a distinctive fish for a carefully planned aquarium.

Care and setup

Provide a soft sand substrate, dim lighting and plenty of cover. Coarse or sharp substrate can damage its sensitive mouthparts. It is sensitive to deteriorating water conditions and many medications, including salt, so choose treatments carefully.
