Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 19.0 cm TL male/unsexed; (Ref. 57235); common length : 8.0 cm SL male/unsexed; (Ref. 57235)
Musculature of the back extending forward to above the front margin of the eyes; dorsal-fin origin slightly in front of the anal-fin origin (Ref. 27732). Pectoral fin not extending beyond tip of pelvic fin; 25-32 branched anal-fin rays; dark outline on first few lateral line canals; 12 gill rakers on 1st arch (Ref. 12693).
Occurs in lowland rivers including streams adjacent to the peat areas (Ref. 57235). Found at the surface in large rivers and lakes. At high water it moves into the flooded forest. Usually occurs together with P. oxygastroides and P. williaminae. Used to make prohac (Ref. 12693).

Estimates based on models
Phylogenetic diversity index (Ref. 82804
= 0.5078 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00617 (0.00290 - 0.01310), b=3.08 (2.91 - 3.25), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.4 ±0.5 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153
): Low vulnerability (10 of 100).
