📖 Overview

Seems to prefer shallow areas near the edges of the lake . Occurs in schools at the surface; stomach of specimens which were examined contained organic debris; benthic and epilithic diatoms, and sponge spicules were nearly always present and many had inorganic particles in the stomach; individuals were seen shoveling sand into the mouth, moving it about in the buccopharynx, then spitting out the sand and making swallowing movements . Lacks marked sexual dichromatism when sexually active . Probably a biparental ovophilic mouthbrooder that forms little to no and only temporary pair bonds .
