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).

Estimates based on models
Índice de diversidade filogenética (Ref.
82804): PD
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.
93245).
Nível Trófico (Ref.
69278): 3.4 ±0.4 se; based on size and trophs of closest relatives
Resiliência (Ref.
120179): médio(a), tempo mínimo de duplicação da população 1,4 - 4,4 anos (tmax=4).
Fishing Vulnerability (Ref.
