Comments: Occurs in clear-water streams and rivers. Larger fish remain during the day lying on soft-bottom patches (mainly on sand, sometimes on leaf litter) at deeper sites and forage mainly during the night at shallower areas with rocky bottom. Grazing during the day were occasionally observed. Small fish forage during the day and night, always in shallower areas. Individuals feed mainly on periphyton from rocky substrates, but also explore from submerged logs and branches (Ref. 97225).
