Range and natural history

It occupies fast riffles over rock in creeks and small to medium rivers. Recorded food includes the larvae of midges and blackflies. The flowing riffle habitat and insect diet place it within the small-animal food web along the river bottom.

The site uses Nothonotus bellus; FishBase uses Etheostoma bellum. ITIS explicitly connects these names as synonyms, so the older genus combination in the linked biological account refers to this species.
