背棘 (总数) : 15 - 17; 背的软条 (总数) : 11 - 15; 臀棘: 3; 脊椎骨: 30 - 31. Diagnosis: A large, deep-bodied species, with wide bands of teeth in the jaws (Ref. 118638). Adult males are covered with complex bright pale blue markings, over the head, flanks and unpaired fins; the background colour can vary from greyish, through yellow to bright red; the lower part of the head is grey-white; the tailfin often head a red background and the dorsal fin has a broad red margin (Ref. 118638). Females and non-territorial males are generally a plain silvery colour, with pearly spots on the flanks; they occasionally exhibit vertical bars and/or horizontal dark bars (Ref. 118638).
Body shape (shape guide): short and / or deep; Cross section: compressed.
颚不延长。 眶前骨深的,24-29% HL。 胸与腹面的鳞片非常小的但是边缘重叠成瓦状。 在固定的宽度的官能性垂直条纹中的身体的黑色素图案, 通常看不见的在较大的保存标本中。

It is the dominant tilapiine species in Lake Tanganyika, despite the presence of the normally invasive Nile tilapia (Ref. 118638). It is not normally found far up into inflowing rivers (Ref. 118638). It has been reported to browse the surface film of sheltered waters; stomachs contained large quantities of the diatoms Pinnularia and Navicula with some sand-grains (Ref. 2). A maternal mouthbrooder; males defend territories in shallow water in sheltered sandy or muddy areas, and dig simple pits in the substrate (Ref. 118638). A large fast-growing species well represented in fishery catches in and around Lake Tanganyika; currently being promoted as an aquaculture species and occasionally exported for the aquarium trade (Ref. 118638).
有时形成鱼群。 曾经报告啃食有遮蔽的水域的表面薄膜。 腹部包含了大量的硅藻 Pinnularia ，而且 Navicula 有一些沙子谷粒。 (参考文献 2)
