A quiet but territorial species. Peaceful towards heterospecifics, although it should not be kept with very active or aggressive species, as it will be out-competed at feeding time.Also known as Peter’s elephantnose, this fascinating species is currently the most common Mormyrid in the hobby. Sadly, its popularity means it is often kept in unsuitable conditions.

Special Requirements - This is a nocturnal fish, so dim lighting is required to make it feel secure. Plenty of cover should also be provided, particularly if you’re keeping a few together. A sand substrate is absolutely critical to the well-being of this species, as it burrows into it with it’s proboscis-like lower lip. Sharp-edged or coarse substrates can damage the mouthparts of the fish and prevent it from feeding naturally.

Tanks Mates and Compatibility –  Buying only 2 is not recommended, as the stronger will often bully the weaker to death. A quiet but territorial species. It is peaceful towards heterospecifics, although it should not be kept with very active or aggressive species, as it will be out-competed at feeding time. It also does not mix well with other mormyrids. Suggested tankmates include other African species such as Butterfly fish, smaller bichirs, Congo tetras, Synodontis catfish and Ctenopoma species. G. petersii can also be kept successfully with peaceful cichlids such as Satanoperca, some Geophagus and Angelfish.

Feeding –  Will accept a range of dried, frozen and live foods. Worms of any kind are a particular favourite
