Inhabit rivers and lakes, also in rapid streams with rocky bottom (Ref. 41236). Grow better in a river with a rocky bottom. Travel toward headwaters at the start of the rainy season and downstream at the end of the rainy season. Omnivorous, feed on filamentous algae, chironomid larvae, water beetles and crustaceans. Spawn from March to September, over stones and gravel (Ref. 40948). Reported to reach 150 cm TL (Ref. 12192), and gain a maximum weight of 68 kg by Thomas, 1897 (Ref. 4832). Considered a long-living species (Ref. 58486).

50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00933 (0.00422 - 0.02065), b=3.01 (2.82 - 3.20), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
栄養段階 (Ref.
69278): 2.6 ±0.1 se; based on diet studies.
回復力 (Ref.
