Lives in slow-flowing streams, ponds and reservoirs. Occurs in isolated pools in riverbeds and some freshwater lakes, swimming close to rocky, gravelly or sandy bottoms. Underwater cavities in river banks and root mounds of sedge tussocks may be utilized for shelter. Tolerant of brackish conditions (Ref. 44894). Benthic (Ref. 75154).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.5 ±0.6 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
