Dimensione / Peso / Età
Maturità: Lm ? range ? - ? cm
Max length : 20.0 cm SL maschio/sesso non determinato; (Ref. 12693)
Spine dorsali (totale) : 9; Raggi dorsali molli (totale) : 14 - 16; Spine anali: 3; Raggi anali molli: 12; Vertebre: 25. First dorsal fin with 8 spines; 7 pectoral filaments, upper two filaments longer than total length; vomer with villiform teeth; orbit diameter 3-4% of standard length; posterior portion of maxilla less than orbit diameter (Ref. 49954).
Found in muddy or sandy waters of freshwater rivers and estuaries (Ref. 57343). Regularly enters freshwater streams during the spawning season, and probably at other times (Ref. 9685). Large numbers of adults and young caught during the rainy season in the Chao Phraya River and other rivers of that system. Feeds on crustaceans, small fishes, and benthic organisms (Ref. 57343). Marketed fresh (Ref. 12693). Small fish may be used as duck feed and fertilizer (Ref. 9685).
