Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 15.0 cm SL male/unsexed; (Ref. 30857)
Usually 12-13 branched dorsal rays; in life, body plain greenish with pink fins, and a dark, vertically elongated blotch above pectoral fin (Ref. 27732).
Found at midwater to bottom depths in large and medium-sized streams. Moves into flooded forests or open fields and begins to re-enter rivers in October. Young of the year are first seen in August. Feeds on periphyton, phytoplankton and some detritus. Usually used to make prahoc (Ref. 12693).
