Body oblong, somewhat compressed, and not deep (depth contained 3.1 to 3.8 times in standard length); mouth large, terminal, and almost horizontal, its posterior edge located at the same level as the anterior rim of the eye; first gill arch with 7 to 9 gill rakers; dorsal fin notched, with 12 to 13 spines and 12 soft rays (XII-XIII, 12); pectoral fins short, not reaching distal edge of pelvic fins; second anal spine longer and thicker than third; back olive green; belly silvery; entire body iridescent (Ref. 55763).
Body shape (shape guide): fusiform / normal.
Benthic-pelagic species of coastal waters which may enter rivers (Ref. 55763). Apparently confined to fresh waters, ascending rivers with moderate currents (Ref. 9114). More abundant near the outlets of rivers and creeks, but not in brackish or marine waters. Reaches at least 640 m elevation and inhabits currents of low to moderate velocity. Feed on crustaceans and fish (Ref. 36880). Marketed fresh (Ref. 9114).
侷限於淡水了, 溯溪且水流平穩的地方.(參考文獻 9114) 更豐富的在河與小溪的出口附近, 但是不在半鹹淡水或海洋中。 達到最少 640 公尺海拔而且居住於低到中速度的水流。 捕食甲殼類動物和魚類。 (參考文獻 36880) 在市場上銷售生鮮地了。 (參考文獻 9114)
