Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 30.0 cm SL male/unsexed; (Ref. 9812); common length : 18.0 cm SL male/unsexed; (Ref. 9812); max. reported age: 4 years (Ref. 127264)
School in shallow coastal waters; enter lagoons, estuaries, and rivers to feed (Ref. 9812). Feed on plant detritus, microalgae, minute benthic organisms, and organic matter in sand and mud; juveniles feed on planktonic algae (Ref. 9812). Oviparous, eggs are pelagic and non-adhesive (Ref. 205). Also caught with stakenets and is marketed fresh (Ref. 9812).
