FBname: Brown chromis
Remark: The Ascension I. population differs from the St. Helena I. population in having a bright spot at the rear end of the base of the dorsal fin.  No genetic differences were found between the two populations that seem closest to the population from Brazil (Rocha et al., 2008).
Comments: 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 <i>Chromis cyanea</i> (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).
