Elephantnose Fish (Gnathonemus petersii) is a weakly electric African mormyrid for experienced freshwater keepers. It is intelligent, nocturnal and bottom-foraging, with a sensitive chin appendage used to probe soft substrate for food.
This is not a beginner community fish. Long-term care needs a mature aquarium, soft sand, subdued cover, careful feeding and calm tank mates that will not bully it or outcompete it at feeding time.
| Care level | Advanced |
|---|---|
| Adult size | About 18-25 cm |
| Minimum tank | 255 litres+ |
| Temperature | 23-28°C |
| pH | 6.0-7.2 |
| Hardness | 2-15 dGH |
| Temperament | Peaceful but territorial toward its own kind |
| Diet | Worms, insect larvae, bloodworm, blackworm and other meaty foods |
Use soft sand, wood, roots, caves, plants and dim areas. Avoid sharp gravel because this species probes the bottom while feeding. Offer small meaty foods after lights dim and make sure it gets food before faster tank mates clear the aquarium.
Suitable companions are calm, medium-sized species that occupy other areas of the tank. Consider Congo Tetra, Yellow-Tailed African Tetra, Feather-Fin Synodontis, Synodontis Petricola Pink or African Knifefish only in suitably large, carefully fed aquariums. Avoid aggressive cichlids and frantic feeders.
