背棘 (總數) : 10; 背的軟條 (總數) : 13 - 14; 臀棘: 3; 臀鰭軟條: 7 - 9. This species is distinguished by the following characters: body moderately deep; greatest depth 2.5-3.0 in SL; preopercular notch and knob poorly developed; vomerine tooth patch triangular, with a medial posterior extension; gill rakers of first gill arch 6-7 + 10-14 - 16-21; caudal fin truncate to slightly emarginate; scale rows on back parallel to lateral line. Colour of back and upper sides dark brown, lower sides and belly whitish with a silver sheen; usually a series of 4-5 narrow yellow stripes on the sides below the lateral line; a distinct round, black spot on the back below the posterior part of the spinous portion of the dorsal fin (Ref. 9821, 90102).
Body shape (shape guide): fusiform / normal; Cross section: oval.
頭部的背面輪廓中等傾斜。 眶前骨非常狹窄的, 它的寬度大約一半的眼直徑。 前鰓蓋骨凹槽與癤瘤發展不良的。 鱗片列背面平行於側線。 背面與上側面深褐色的; 下側與腹面微白色的具有一個銀色的光輝。 時常在側線之下側邊上有一系列的四或五條狹窄的黃色斑紋。 一個突出的圓, 在背鰭的刺狀部分的後面的部份之下的在背部上的黑色的斑點。 L. ehrenbergii 有別於 L. fulviflamma 在平行於側線的上背部上藉著具有鱗片列.(參考文獻 37816)

Adults inhabit very shallow coastal habitats, often in large schools near freshwater run-offs (Ref. 48635). Juveniles often intertidal (Ref. 48635); over sand, silt, or coral rubble bottoms, occasionally in mangrove-lined streams and estuaries (Ref. 9821) They may enter freshwater to feed (Ref. 245); on small fish and invertebrates (Ref. 5213). This is a small species commonly utilized in subsistence fisheries and also seen in markets. Caught mainly with handlines, traps, and gill nets and are marketed mostly fresh (Ref. 9821).
