Copionodontines occupy the upper reaches of fast-flowing streams on rocky beds, often with tiny or no water flow in the dry season. Fish tend to concentrate on quiet, deep pools, though some individuals lodge in narrow rock crevices in fast-flowing sectors. Habitat preferences also vary according to

species. Water in the upper reaches of the
Chapada Diamantina is cool and usually black (organic matter-stained), but copionodontines are recorded in a few clear-water streams, as well. Usually, they share their environment with few or no other fish species.
