Comments: Adults live mainly in small, clear, flowing streams with gravel or sand bottoms from near sea level to about 1800 m elevation.  May be cryptic, living among log debris and boulders, or sometimes found in loose shoals in more open conditions.  Also occur in small upland tarns where they may be found shoaling in open water.  Tolerant of very cold water, they have been collected from a tarn surrounded by deep snow.  Life cycle (maximum life span of about 4 years) is restricted to fresh water.  Feed on benthic and drifting invertebrates.  Mature individuals breed in spring (sometimes extending to autumn); adults move upstream into shallow riffle areas to lay their demersal, adhesive eggs over rocky bottoms (Ref. 44894).
