Issue
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).

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).
通常出現於陡坡與礁坪中。 一個日行性種 (參考文獻 9626), 它最通常形成在礁頂上的中等大小的覓食群集,上升到底部上面覓食浮游生物, 主要地橈腳類的動物。 時常與 Chromis cyanea 一起出現。 (參考文獻 9710) 很少在市場上銷售。 (參考文獻 3139)
