Environment:	reef-associated; non-migratory ; depth range 10 - 12 m
Climate:	subtropical; 35°N - 35°S
Global Importance:	aquarium: commercial
Resilience:	High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.)
Distribution:	Indo-Pacific: Red Sea to the Line, Marquesan, and Tuamoto islands, north to the Ryukyu Islands, south to New Caledonia.
Diagnosis:	Dorsal spines (total): 12-12; Dorsal soft rays (total): 9-11; Anal spines: 2-2; Anal soft rays: 9-11.

Looks similar to C. atripectoralis, but generally smaller and lacks the black area on the inside of the pectoral fin base.
Biology:	Found in large aggregations above thickets of branching Acropora corals in sheltered areas such as subtidal reef flats and lagoons. Juveniles closely tied to individual coral heads (Ref. 9710). Phytoplankton feeders. Breeding is done on sand and rubble. Males prepare nest for spawning which is shared with several females. Large number of eggs spawned hatching in 2-3 days. Males guard the nest ventilating fertilized egg with their caudal fins and feeding on those which do not hatch
