背棘 (總數) : 16 - 17; 背的軟條 (總數) : 10 - 11; 臀棘: 3; 臀鰭軟條: 8 - 10. Diagnosis: A heavily-built large tilapia species with a wide rounded head; dwarf populations exist in some crater lakes, showing bony 'hunger-form' body shape (Ref. 118638). Females and juveniles with grey bodies and 6 or more vertical bars; males have a bright blue, occasionally white or green, 'mask' across the head; when fully ripe, the underside of most of the body can be black, with the upper surface a conspicuous white to pale blue; genital tassel can be long and branched, pinkish to bright yellow; females and non-territorial males are indistinguishable from Oreochromis karongae (Ref. 118638).
Body shape (shape guide): fusiform / normal; Cross section: compressed.
低的咽有齒的區域有凹的側邊; 硬骨 1.26-1.36 的平均長度倍於它的寬度與 37.6-40.6個頭長; 葉片 1.6-2.4 倍於有齒區域的平均長度。 尾鰭有鱗的。

A semi-pelagic species (Ref. 4967), found in all kinds of habitats but seen mostly in shallow water; it is abundant in the southeastern arm of Lake Malawi, where it occurs in shallow, vegetated bays (Ref. 5595). It feeds on phytoplankton and sometimes from the sediment on the sand; diatoms constitute the major part of its diet (Ref. 5595). Major component of the fisheries catch in Lake Malawi (Ref. 118638). IUCN conservation status is endangered, due to declining population trend (Ref. 118638).
生存在一個 21.5-29 °C(參考文獻 2) 的溫差, 在各種的棲息地但是被見到主要在淺水區。 在水淺的長滿植物的海灣中很豐富。 形成魚群。 吃浮游植物, 主要地矽藻, 與有時在沙子上的從沉澱物.(參考文獻 5595)

Mating behavior includes the T-stand, both partners alternately forming the horizontal part of the T. Eggs are laid in batches and immediately picked up by the female. Fertilization takes place both on the ground and in the mouth. Females brood eggs/young, guarding their fry until about 15 mm (Ref. 2781). 非洲: 馬拉威湖的特有種。
