Care at a glance
The elephant nose fish from West Africa has no real trunk, but a mobile, extended chin appendage with which it probes the bottom for food. It generates weak electrical pulses to orient itself and even to communicate with its own kind, and has an exceptionally large brain relative to its body.
It is sensitive, shy and needs a mature tank with soft sand, plenty of hiding places and subdued light. It eats almost exclusively live or frozen food such as bloodworm and must be fed deliberately in the evening, because in the bustle of a community tank it never gets its share.
