Prefers open water regions at greater depths, but ventures into the more shallow areas of the lake for spawning, which normally occurs during the rainy season; mainly feeds on phytoplankton and small insects; probably ovophilic mouthbrooder; males occupy a tertitory of ca. 50 cm and it is often possible to find large numbers of males in a limited area (Ref. 52307).
在较大的深度偏爱开放水域区域, 但是冒险进入湖的较浅的浅滩区域产卵; 主要地吃浮游植物与小的昆虫; 可能 ovophilic 口孵者.(参考文献 52307)
