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).
在較大的深度偏愛開放水域區域, 但是冒險進入湖的較淺的淺灘區域產卵; 主要地吃浮游植物與小的昆蟲; 可能 ovophilic 口孵者.(參考文獻 52307)
