Kort beskrivning Bestämningsnycklar | Morfologi | Morfometri
Taggstrålar i ryggfenan (totalt) : 13 - 15. Diagnosis: A small, deep-bodied species with a narrow head and small strong jaws (Ref. 118638). Often appearing a rich deep yellow with wide dark brown bands, and red/orange fin margins; mature adults are very dark with prominent black stripes and a patch of scarlet scales behind the head (Ref. 118638).
Body shape (shape guide): fusiform / normal; Cross section: oval.
Body shape (shape guide): fusiform / normal; Cross section: oval.
Adults are found in widely diverse habitat (Ref. 3); they favor areas where plant cover exists along the edges of rivers, lakes or swamps (Ref. 3), but tend to be confined to shallow weedy areas, so ithey do not build up large populations in deep lakes (Ref. 118638). They are reported to be cold-confined (Ref. 118638). Adults are omnivorous, feeding on animal and plant matter (Ref. 118638), preferentially on filamentous algae, aquatic macrophytes and vegetable matter of terrestrial origin like leaves, plants, etc. (Ref. 3). Juveniles feed on small crustaceans and midge larvae (Ref. 6465). It is forage fish for bass (Ref. 7248). A substrate spawner (Ref. 52307, 118638). Male and female form pairs to rear the young (Ref. 118638). It undertakes seasonal upstream migration and breeds before and during these migrations (Ref. 13337, 52307). A relatively small species, so unlikely to play much of a role in capture fisheries, but cultured in ponds in Njombe, Tanzania, and apparently stocked into Lake Kiungululu, Tanzania, where it is not presently exploited (Ref. 118638).

A substrate spawner (Ref. 118638). Male spreads his milt over the cluster of eggs which are deposited on the bottom or even attached to the branches of aquatic weeds; parents guard the eggs; eggs and fry may be moved into the mouth to alternative sites during hatching operations but there is no evidence of actual mouth brooding (Ref. 13337).
