Occur in gravel-bottomed pools, runs of creeks, small rivers (Ref. 5723) and streams (Ref. 10294); usually found in debris. Spawn in headwaters (Ref. 5723, 10294). Adults feed on aquatic isopods, amphipods (Hyalella), mayfly nymphs (Stenonema, Leptophlebia), midge larvae, and limpets (Ref. 10294). Eggs are found attached to the substrate unguarded (Ref. 7043).

Estimates based on models
Fylogenetische diversiteitsindex (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00537 (0.00235 - 0.01227), b=3.14 (2.94 - 3.34), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trofisch niveau (Ref.
69278): 3.3 ±0.5 se; based on size and trophs of closest relatives
Weerstandsvermogen (Ref.
120179): Hoog, minimale populatieverdubbelingstijd minder dan 15 maanden (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
