Adults inhabit passages and outer reef slopes, solitarily or in small groups. They are sometimes seen in mixed aggregations with the closely related species C. margaritifer (Ref. 7247). Feeds on planktons (Ref. 89972). 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). Diurnal species (Ref. 54980; 113699).
栖息于通道与外礁斜坡, 单独地或形成小群鱼群。 有时用近亲鱼种 C. margaritifer 被在混合的群集中见到。
