Occur in pairs occupying the same burrow, but at times more than 2 individuals will retreat to the same refuge (particularly true for juveniles). Monogamous (Ref. 52884). Feeds on zooplanktons (Ref. 89972).
栖息于舄湖与临海礁石, 在碎石与沙底部之上。 (参考文献 9710) 从水浅的淤泥河口发现了，而且外围礁石舄湖的小水湾到大约 10 公尺深度, 但是可能也被在海岸的斜坡到 25 公尺深度上深地见到.(参考文献 48637) 成对出现占领相同的洞穴，但是偶而超过 2个个体将撤退到相同的藏身处。 (特别是稚鱼时) 一夫一妻的.(参考文献 52884)
