Etymology: Tilapia: Bechuana, African native thiape = fish (Ref. 45335).
Eponymy: Dr Anders Erikson Sparrman (1748–1820) was a Swedish explorer, collector and naturalist who explored the Cape area of South Africa (1772–1776). [...] (Ref. 128868), visit book page.

Max length : 23.5 cm TL 雄魚/尚未辨別雌雄; (Ref. 27292); 最大體重: 445.00 g (Ref. 7248)
背棘 (總數) : 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.
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).
出現於廣泛不同的棲息地。 喜歡植物覆蓋的區域存在沿著河，湖或沼澤的邊緣。 偏愛水淺且有遮蔽的水域與不會移殖至大湖的開放水域。 成魚先取地吃吃絲狀的藻類, 水生的大型植物與陸棲起源 (樹葉，植物, 等等。) 的植物。 (參考文獻 3) 稚魚吃小型甲殼動物與蚊仔魚。 (參考文獻 6465) 為 bass 的餌料魚.(參考文獻 7248) 進行季節性的溯溪迴游與繁殖在與之前在這些迴游的時候.(參考文獻 13337)

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。
