Morphology | Morphometrics
Occurs in lakes, swamps and rivers, including turbid backwaters and clear, flowing tributaries (Ref. 2847). Inhabits bottom of warm, clear, flowing streams; also lives in billabongs and flooded lagoons (Ref. 44894). Feeds on insects, prawns, mollusks and small crayfish (Ref. 5259, 44894).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5005 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00457 (0.00197 - 0.01058), b=3.07 (2.86 - 3.28), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.5 ±0.50 se; based on food items.
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low to moderate vulnerability (26 of 100) .
