Facultative air-breathing (Ref. 126274); A resident intertidal species with homing behavior (Ref. 32612, 48637) and amphibious air-breather (Ref. 31184, 79840), found in brackish mud flats in mangrove and nipa palm areas. Found in both littoral and estuarine; able to climb out of water, in mangrove swamps and burrowing into intertidal mud banks (Ref. 4756). Occasionally in the lower parts of freshwater streams (Ref. 2847, 44894, 48637, 79840). Actively shuttling back and forth between rock pools and air (Ref. 31184). It feeds on worms, crustaceans, and insects (Ref. 37816). Can stay out of the water for up to 37 h if kept moist (Ref. 51276).
一个定居的潮间带的种有归巢的行为 (参考文献 32612,48637) ，而且两栖的呼吸空气的鱼类 (参考文献 31184) 在红树林与尼帕棕榈树区域中发现于半咸淡的淤泥平台了。 偶见于淡水溪流的下面部份。 (参考文献 2847,44894,48637) 活跃地穿梭移动在岩石区潮池与空气之间往前与往后。 (参考文献 31184) 吃蠕虫，甲壳动物与昆虫。 (参考文献 37816) 如果保持潮湿，能离开水面停留超过 37 h 。 (参考文献 51276)
