Adults inhabit lagoons, estuaries and freshwater (Ref. 6028, 48637, 79840). They occur in the lower reaches of freshwater streams, usually on mud bottoms (Ref. 44894). Juveniles are found mainly among mangrove roots in the more saline areas of lagoons and estuaries (Ref. 6028, 79840). Carnivorous (Ref. 79840). Marketed fresh (Ref. 12693).
栖息于舄湖，河口与淡水水域。 (参考文献 6028,48637) 出现于淡水溪流的下面范围, 通常在泥底上.(参考文献 44894) 稚鱼主要地在舄湖与河口的盐分较高区域中的红树林根部之中被发现。 (参考文献 6028) 肉食性。 在市场上销售生鲜地了。 (参考文献 12693)
