Overview

Considered the true “jewel cichlid” of hobbyists, and now placed in the genus Rubricatochromis, it is also used as a study animal by physiologists and ethologists. It has three black spots on its flanks, one of them on the caudal peduncle, against two in H. lifalili, which has become more popular.

Scientific name
Rubricatochromis bimaculatus (Gill, 1862)Current valid name; in the hobby: Hemichromis bimaculatus
Classification
Cichliformes › Cichlidae
IUCN Red List
Least concern (LC)

Natural habitat

West Africa: from Guinea to central Liberia (including Sierra Leone)

Observations (GBIF) and localities Native countries Rivers and lakes

It lives in small streams and canals over mud or sand, under overhanging and floating vegetation, inland, in intact or recently disturbed forest.

Behaviour

Despite common practice, it suits neither beginners nor community tanks: territorial, it becomes extremely aggressive when breeding. It lives with large Alestidae (Congo tetras), Synodontis, Loricariidae and, in a large tank, other African cichlids such as Steatocranus. Keep it in a pair, ideally formed within a group of juveniles. It eats almost anything, with live prey and plant matter.
