This species is distinguished from its congeners by the following set of characters: mouth subterminal, weakly oblique to nearly horizontal (less than or equal to 20° to midline of body); presence of maxillary barbels; edge of rostral cap is straight, no medial indent; most specimens, particularly larger individuals, have longitudinal stripes on flanks; caudal peduncle with small brown spot at medial insertion of caudal fin in smaller specimens; caudal fin is mostly clear, with scattered melanophores; pectoral, pelvic, and anal fins hyaline in life (Ref. 123185).
Found at bottom depths in canals, ditches and small streams in large river floodplains. Migrates up small rivers and streams and out onto floodplains. Feeds on phytoplankton, periphyton, benthic algae, detritus and some zooplankton. Most likely used to make prahoc (Ref. 12693).
