Inhabits rocky riffles, runs, and flowing pools of clear creeks and small rivers. Rarely found in springs and along wave-swept margins of large impoundments (Ref. 5723, 10294). Feeds on aquatic insect immatures (midges, mayflies, caddisflies) and small crustacea (isopods, amphipods, copepods) (Ref. 10294).

50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00562 (0.00251 - 0.01261), b=3.10 (2.90 - 3.30), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.

营养阶层 (Ref.
69278): 3.4 ±0.4 se; based on size and trophs of closest relatives
回复力 (Ref.
