Μέγεθος / Βάρος / Age
Maturity: Lm ?  range ? - ? cm
Max length : 12.0 cm SL αρσενικό/απροσδιόριστο; (Ref. 2847)
Ραχιαίες άκανθες (συνολικά) : 0; Μαλακές ραχιαίες ακτίνες (συνολικά) : 12 - 13; Εδρικές άκανθες: 0; Μαλακές εδρικές ακτίνες: 29 - 36. Belly with 17 to 19 + 10 or 11 = 27 to 29 keeled scutes from isthmus to anus. Maxilla short, not quite reaching to hind border of pre-operculum; first supra-maxilla short, not more than half length of second. No black area behind upper part of gill opening.
Inhabits turbid channels of large rivers, also lakes and swampy backwaters (Ref. 2847). The very high number of gillrakers suggests filter-feeding habit (Ref. 189). Feeds on plankton including calanoid copepods (Ref. 2847).
