Occurs in standing or slow-flowing pools with a soft or rocky bottom. Thrives in dams and tolerates turbid waters. Juveniles occur in large shoals, adults in small groups. Feeds off the substrate on algae and detritus. Breeds in summer, moving into riffle areas to lay eggs (Ref. 7248).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00525 (0.00226 - 0.01220), b=3.11 (2.90 - 3.32), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
栄養段階 (Ref. 69278):  2.0   ±0.00 se; based on food items.
Generation time: 4.2 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
回復力 (Ref. 120179):  高い, １５か月以下の倍増期間の最小個体群 (K=0.26; tm=1; tmax=3).
Fishing Vulnerability (Ref. 59153):  Low to moderate vulnerability (35 of 100).
価格帯 (Ref. 80766):   Unknown.
