The dorsal fin is supported by 12 hard rays and 12 to 14 soft rays. In the anal fin there are 2 hard and 12 to 14 soft rays and in the pectoral fins 17 or 18 soft rays. The number of lateral line scales is 15 to 17. The bright caudal fin is deeply forked.
Way of life
The fish live in small groups at depths of 3 to 65 meters in lagoons and outer reefs, usually near caves and crevices in the reef rock or over branching hard corals . They feed on zooplankton . Pairs form for reproduction. The eggs clinging to rocks are cared for and guarded by the male until the young fish hatch.
