| Distribution: |
Western Atlantic: Florida and Texas (USA) and throughout the Caribbean Sea to Brazil (Ref. 9626, 35834). Eastern Atlantic: St. Helena and Ascension islands and from São Tomé. |

A prominent black spot at the pectoral-fin base, and a white spot just behind the posterior base of the soft dorsal fin (Ref. 7247).

| Biology: |
Adults generally occur in steep slopes and patch reefs. Diurnal species (Ref. 9626), they most commonly form moderate-sized feeding-schools over reef tops, rising above the bottom to feed on plankton, mainly copepods. Often seen with Chromis cyanea (Ref. 9710). Oviparous, distinct pairing during breeding (Ref. 205). Eggs are demersal and adhere to the substrate (Ref. 205). Males guard and aerate the eggs (Ref. 205). Rarely marketed (Ref. 3139). |
