Amblyeleotris rubrimarginata is a fish in the family Gobioidei, the gobies. It is found on reefs or in seagrass beds in the western Pacific, from New Caledonia to the Great Barrier Reef and around New Guinea, Indonesia, Malaysia and the Philippines, at depths from 3 to 26 metres (10 to 85 ft). As with other Amblyeleotris species, it has a symbiotic relationship with alpheid shrimps, with an individual or a pair of gobies sharing a burrow with a pair of shrimps. A. rubrimarginata is up to 8 centimetres (3.1 in) in length, and its background colour is whitish, marked with five vertical brown or orange bars. It is most readily distinguished from its congeners by a row of red spots along the margin of both dorsal fins and the upper part of the caudal fin, and also by a prominent black spot just above and behind the eye. This A. rubrimarginata fish was photographed at the resort of Anilao in Mabini, Batangas, in the Philippines.
