Occurs in a variety of habitats, but seems to prefer large rivers with slow current (Ref. 27732). Common along shores in large rivers (Ref. 56749). Found at or near the surface in clear waters of rivers and streams. Generally prefers a depth of about 5 m. Feeds mainly on exogenous insects, some small crustaceans and algae (Ref. 12693).

50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00851 (0.00376 - 0.01926), b=3.07 (2.87 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
营养阶层 (Ref.
69278): 2.9 ±0.36 se; based on food items.
Generation time: 2.9 ( na - na) years. Estimated as median ln(3)/K based on 2
growth studies.
回复力 (Ref.
