Maturity: Lm ? range ? - ? cm
Max length : 23.5 cm TL 雄鱼/尚未辨别雌雄; (Ref. 27292); 最大体重: 445.00 g (Ref. 7248)
背棘 (总数) : 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).
Found in widely diverse habitat (Ref. 3); it favors areas where plant cover exists along the edges of rivers, lakes or swamps (Ref. 3), but tends to be confined to shallow weedy areas, so it does not build up large populations in deep lakes (Ref. 118638). It is 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).
出现于广泛不同的栖息地。 喜欢植物覆盖的区域存在沿着河，湖或沼泽的边缘。 偏爱水浅且有遮蔽的水域与不会移殖至大湖的开放水域。 成鱼先取地吃吃丝状的藻类, 水生的大型植物与陆栖起源 (树叶，植物, 等等。) 的植物。 (参考文献 3) 稚鱼吃小型甲壳动物与蚊仔鱼。 (参考文献 6465) 为 bass 的饵料鱼.(参考文献 7248) 进行季节性的溯溪回游与繁殖在与之前在这些回游的时候.(参考文献 13337)
Life cycle and mating behavior
Maturities | 繁殖 | Spawnings | Egg(s) | Fecundities | 仔鱼
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).非洲: Shaba ， Kasai 上游， Dwango 上游， Cuanza ，庫內內河，奧塔萬戈河，那米湖，尚比西河，凌波波河， Sabi ， Lundi 上游, 橘河，馬拉威湖， Bangweulu 與 Moero 的北部支流。
