Environment: milieu / climate zone / depth range / distribution range
Freshwater; demersal; depth range - m (Ref. ), usually - m (Ref. ). Tropical; 0°C -

Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 42.0 cm TL male/unsexed; (Ref. 4903)
Found in most areas of the lakes and rivers from which it has been collected (Ref. 49805). Generalist feeder (Ref. 12526, 49805). Insectivorous as juvenile, adults eat Caridina, small fishes, and Povilla and Odonata larvae (Ref. 12526). Prawns, water weed and oligochaetes have also been found in the stomach (Ref. 49805). Mabybe spawns in rocky riverine habitats (Ref. 12526).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [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
): 3.2 ±0.4 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
): Low to moderate vulnerability (32 of 100) .
