| Biology: |
Inhabits outer reef slopes. Occurs in aggregations, most frequently in clear waters of outer reef slopes and passes in depths ranging from about 3 to 15 m (Ref. 54301). Feeds mainly on zooplankton and swims up to several meters above the bottom while feeding (Ref 54301). When threatened by passing divers or predators the anthias hastily retreat to the safety of rocky crevices. It has a harem-type of social structure, with each male controlling a group of females. When courting, the male color is greatly intensified and the bright red dorsal fin is fully erected (Ref. 54301). |
