Range and natural history
It inhabits clear, fast-flowing riffles over rock in creeks and small to medium rivers. Breeding involves distinct pairs, and eggs are produced in batches. These observations describe the flowing-water reproductive setting rather than a general lake-spawning pattern.
The California Academy of Sciences documents Etheostoma juliae as the historical name and Nothonotus juliae as the currently accepted combination. That source establishes the connection to the biological summary used here.
