Comments: Found in the lower freshwater reaches of streams, 50 to 800 m from the upper limit of tidal fluctuations. The habitat is almost the same as that of <i>S. ninja</i> and they were often observed syntopically, and sometimes with <i> Schismatogobius marmoratus</i>. Major syntopic fishes were also the same as those with <i>S. ninja</i>. This species also has camouflage coloration. This species often spreads its pectoral fins and flutters them and although the proximal part of the large black patch on the pectoral fin is covered by white pigmentation on the anterior side, it lacks white pigmentation on the posterior side. Thus, the black patch on the posterior side is conspicuous during the fluttering behavior. They communicate with other individuals by this behavior, but the meaning is unknown (Ref. 125666).
