📖 Overview

Facultative air-breathing in the genus ; Found in stream with dark, slightly turbid water, flowing through a landscape of mixed low forest and pasture . Collected at the margin of an open field, but the stream flowed through dense low forest left along its bank and providing shadow . Usually occurs in areas with sandy bottom, bank vegetation entering water or with marginal aquatic plants, dark, clear or slightly turbid water and limited associated fauna . Mimics Corydoras diphyes . Mimicry is unusual because the two species occupy different microhabitats and it is hypothesized to operate with a primarily visual predator moving between the microhabitats, tentatively identified as the cichlid Crenicichla lepidota .
