Inhabit lagoons often among algal or seagrass beds (Ref. 5503). Found on sand or silt bottoms, frequently in bays or estuaries (Ref. 3132). They are opportunistic feeders that collect mainly epifaunal and interstitial invertebrate prey, e.g., crustaceans and worms from the sediment-water interface (Ref. 31134). Shed their skin in one piece with a rapid jump periodically to rid themselves of accumulated ballast (Ref. 31134). Adults usually in pairs on muddy substrates (Ref. 48635). Has a monogamous mating system with close-pair bonding (Ref. 90102).

Life cycle and mating behavior
成熟度 | 繁殖 | 产卵场 | 卵 | 孕卵数 | 仔鱼
Are broadcast spawners. In several aquaria, spawning is observed as pairs rose to about 50 cm above the substrate, their ventral surfaces closely opposed, releasing gametes at the apex of their upward rush; then they glided down to the bottom. As the pairs landed on the substrate, the male continued to follow his mate. Release of gametes follows. Spawning occurred only within pairs (obligate and genetic monogamy) (Ref. 52884).印度-太平洋: 對馬貴斯群島與社會群島的紅海與南非 (參考文獻 4264), 北至日本南部, 南至澳洲與羅得豪島; 在密克羅尼西亞各處。
