Maturity: Lm ?  range ? - ? cm
Max length : 25.0 cm SL male/unsexed; (Ref. 36377)
Inhabits lakes, preferring mesotrophic waters with a mud or sand bottom. Some populations have migrated into the lower river valleys with slow to moderate flowing waters. Feeds mainly on plant and vegetable matter supplemented by invertebrates and aquatic insects.

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5039 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02692 (0.01216 - 0.05956), b=3.04 (2.86 - 3.22), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 2.7 ±0.27 se; based on food items.
Resilience (Ref. 120179
): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low to moderate vulnerability (32 of 100) .
