Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 30.0 cm TL male/unsexed; (Ref. 55763); common length : 15.0 cm TL male/unsexed; (Ref. 55763)
Body diamond-shaped, compressed, and deep (depth contained 1.9 to 2.0 times in standard length); predorsal profile very compressed; mouth strongly protractile; preopercular border serrate; dorsal fin not notched to its base; second anal spine long and stout; body silver or gold with blue iridescent highlights; pelvic and anal fins yellow with dark rays (Ref. 55763).
Common in coastal waters. Juveniles inhabit lagoons of mangrove areas and tidal streams; adults are found over soft bottoms of deeper waters. May enter brackish waters (Ref. 37955). Feeds on benthic invertebrates and fishes. Its flesh is considered of good quality (Ref. 9303). Depth range assumed (RF).
