The adults and juveniles were usually found on emergent plants in daytime, motionless near riverbanks at night, with the latter also occurring in tide pools with muddy or gravel bottoms. Associated with other amphidromous eleotrids, Eleotris fusca and Giuris tolsoni, inhabiting the same site. Also often observed with Eleotris acanthopomus and Redigobius bikolanus. Consumed in Japan (Ref. 133165). Kobayashi, H. and M. Sato 2023 The genus <i>Ophiocara</i> (Teleostei: Butidae) in Japan, with descriptions of two new species. Ichthyol. Res. 71(1):119-153.

Colouration: trunk with two beige oblique bands; dorsal and caudal fins with dark brown spots; juveniles with white or light brown markings on middle and ventral parts of caudal fin base (Ref. 133165).

Refers to fishes that regularly migrate between freshwater and the sea (in both directions), but not for the purpose of breeding, as in anadromous and catadromous species. Sub-division of diadromous. Migrations should be cyclical and predictable and cover more than 100 km.Characteristic elements in amphidromy are: reproduction in fresh water, passage to sea by newly hatched larvae, a period of feeding and growing at sea usually a few months long, return to fresh water of well-grown juveniles, a further period of feeding and growing in fresh water, followed by reproduction there (Ref. 82692).
