Issue
This species is placed in the genus Macropleurodus Regan, 1822 in Eschmeyer (CofF ver. Mar. 2011: Ref. 86697). We keep all the lacustrine and riverine "Haplochromine" species of the Lake Victoria catchment in the genus Haplochromis Hilgendorf, 1888 following Van Oijen et al. (1996: Ref. 12750), until a new complete taxonomic revision is published.

Occurs in the littoral and sublittoral regions, especially where the bottom is hard, only rarely over mud (Ref. 5662). Feeds mainly on snails and insect larvae (Ref. 558) as well as on detritus and phytoplankton (Ref. 28676). In combination, the introduction of top-predator Lates niloticus (and probably other species of Lates), together with intensified fishing efforts, appear to be responsible for the virtual disappearance of this species over the last 20 years (Ref. 26184).
出現於沿海地區與亞潮帶區域, 尤其底部是堅硬的只有很少超過泥的地方.(參考文獻 5662) 主要吃蝸牛與昆蟲幼生 (參考文獻 558) 以及碎屑與浮游植物。 (參考文獻 28676) 在組合，頂端-掠食者 尼羅尖吻鱸〔Lates niloticus〕 (與可能其他種的 晚 ) 的引入, 伴隨著增強漁業努力, 在最後的 20 年以來狀似是這種的虛擬消失的原因.(參考文獻 26184)
