This occasionally schooling species is found in inshore sandy and muddy areas. Also found in ecotones near hard bottoms (Ref. 92840). Juveniles found in lower estuaries. Mainly diurnal, this species feeds on small polychaetes, amphipods (corophiids, caprellids), cumaceans and mysids (Ref. 4696). Spawns in summer in shallow waters. Male lures the female into an empty bivalve shell where she lays a portion of eggs. Guarded by the male for 10 days until larvae about 3 mm long. Larvae are pelagic at first. Young fish only start to live at the bottom when 17-18 mm (Ref. 35388).
这偶然群游性种被发现于近海沙泥区域。 稚鱼发现于下游河口了。 主要日行性, 这种吃小的多毛类动物，片脚类动物 (corophiids, caprellids) ， cumaceans 与糠虾.(参考文献 4696) 产卵在夏天在浅水区中。 雄性引诱母鱼进入她生下卵的部分的一个空的双壳贝。 达 10 天由雄鱼保卫了直到仔鱼大约 3 mm 长。 仔鱼起先是大洋性的。 幼鱼只开始生活在底部当 17-18 mm.(参考文献 35388)
