在身体上的侧边上银色的有大约七条模糊的略带桃色的横带; 腹鳍黄色.(参考文献 13442)
Inhabits shallow coastal waters in open sandy and surf areas, seagrass beds, near reefs, and mangrove channels (Ref. 7251). Enters brackish water, sometimes even fresh water (Ref. 3722). May occur in small aggregations (Ref. 3722). Feeds on benthic invertebrates such as worms, clams, crustaceans (Ref. 3722); also feeds on insects (Ref. 9303). Often seen feeding in sand patches among reefs by thrusting its mouth into the sediment and expelling sand from the gill openings (Ref. 13442). Easily approached (Ref. 9710). Marketed fresh but not highly esteemed; also processed into fishmeal (Ref. 3722).
在礁的附近，在开放的沙与碎浪区域，海草床中栖息于沿岸浅水区, 与红树林峡道.(参考文献 7251) 进入半淡咸水, 有时甚至淡水.(参考文献 3722) 可能形成小群鱼群。 (参考文献 3722) 吃底栖的无脊椎动物例如蠕虫，蛤, 甲壳动物;(参考文献 3722) 也吃昆虫。 (参考文献 9303) 时常出现藉由插入它的嘴进入沉淀物而且驱逐沙子从鳃裂觅食于在礁之中的沙子区块。 (参考文献 13442) 容易接近。 (参考文献 9710) 在市场上销售生鲜地了但是不是深受喜爱; 也加工成鱼粉。 (参考文献 3722)
