From southern Mozambique, throughout the periphery of the Indian Ocean, the Malacca Strait, the Melanesian Islands, South and East China Sea, Philippine Sea, and in Japan to southern Kyushu. They are also found in Indonesia south to northwestern and northeastern Australia and across northern Australian waters to southern Great Barrier Reef, the Coral Sea, Palau, Guam, New Caledonia, Fiji and Cocos (Keeling) Islands. They are found in waters up to 30 meter near tropical coral reefs.

Mates in shallow water.Their eggs hatch in 38 to 40 days. During the breeding season, males establish a territory, defending a coral head where females lay eggs after mating. Courtship is highly ritualized and involves striking visual displays. Males often guard females to ward off other males. This species mates head-to-head and the male places spermatophoresexternal link on the female’s buccal membrane near her mouth. The eggs harden after they are laid, which makes them difficult for predators to extract from the coral.
