Doublebar Chromis

Chromis opercularis

The Doublebar Chromis is a reef-associated fish found in tropical marine environments. It inhabits regions from South Africa to Kenya, extending to the Maldives, Andaman Sea, and Australia. Typically residing at depths between 4 to 40 meters, this species prefers outer reef slopes and deep lagoons, forming small to moderate aggregations on reef crests where currents are moderate. Identifiable by its distinct coloration, the Doublebar Chromis features broad black bands along the preopercular and opercular margins. Adults have a transparent distal half on the soft-rayed portion of the dorsal fin, while juveniles display a dark blue hue on the spinous portion of the dorsal and pelvic fins. The caudal peduncle and fin are tinged yellow, and the soft-rayed portions of the dorsal and anal fins are yellowish. The species is oviparous, with distinct pairing during breeding. The eggs are demersal, adhering to the substrate, and males play a crucial role in guarding and aerating them. According to the IUCN Red List, the Doublebar Chromis is classified as Least Concern.
