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).

Grayish brown on back, shading to silvery gray on sides; dorsal fin broadly edged with bright yellow; upper and lower edges of caudal fin narrowly yellow with a submarginal dark band (Ref. 13442).

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).
通常出现于陡坡与礁坪中。 一个日行性种 (参考文献 9626), 它最通常形成在礁顶上的中等大小的觅食群集,上升到底部上面觅食浮游生物, 主要地桡脚类的动物。 时常与 Chromis cyanea 一起出现。 (参考文献 9710) 很少在市场上销售。 (参考文献 3139)
