Found in rocky rapids and cascades in altitudes of 900-1,200 m; prefers deeper waters (30-60 cm) over cobbles (Ref. 26172, 52193). It feeds on benthic invertebrates such as mayfly and caddis fly nymphs, blackfly and midge larvae and small snails (Ref. 52193). Oviparous (Ref. 205). Breeds during summer and is a partial spawner (Ref. 52193). Increasing extraction and regulation of river water as well as pollution threaten this species (Ref. 7248).
