Comments: This species is found in the tidal zone within or around mangroves in estuaries, and where four of the seven specimens were found hovering in small tidepools around the roots of mangrove trees [<i>Bruguiera gymnorhiza</i> (L.) Savigny] within the forest at night. The substrate of the tidepool was mud, and a thalassinid mud lobster, <i>Thalassina anomala</i> (Herbst, 1804) made a burrow system around the tidepool. Other fish species observed in that tidepool include <i>Bostrychus sinensis, Eleotris melanosoma, Mugilogobius chulae</i>, and <i>Pisodonophis boro</i>). One individual was found inside a polyvinyl chloride pipe buried in the muddy gravel bottom along the main course of the stream during the daytime, and this site was approximately 10 m from the mangrove. Another individual was collected from the burrow of an unknown builder on muddy substrate using a suction pump during the daytime. One juvenile specimen was found in a similar tidepool on Ishigaki Island, Japan. (Ref. 129074).
