📖 Overview

Found throughout the lake, but seems to prefer zones with submerged wooden or stone structures . Usually forms schools at the surface; feeds mainly on epiphytic and epilithic filamentous algae, and the diatoms, rhizopods, rotifers and organic debris found among them; adults feed by opening their mouths very wide and applying them to the surface of the rock as though sucking the material in . Lacks marked sexual dichromatism when sexually active . Both sexes are possible incubators . Forms temporary pair bonds , for the entire duration of incubation/broodcare .
