Twinspot Chromis

Azurina elerae

The Twinspot chromis is a small reef fish reaching a maximum length of 7.0 cm. It features a grayish-brown body with edges of scales that may appear orangish or bluish. Notable markings include a blackish region around the anus and a blackish spot at the upper base of the pectoral fin. The dorsal and anal fins are marked with a whitish spot on their posterior halves. This species has large eyes and a compressed, fusiform body shape. Twinspot chromis are found in the Indo-West Pacific region, ranging from the Maldives to Fiji and Micronesia, excluding the Marshall Islands. Their range extends north to Taiwan and south to the Philippines and Australia. These fish are typically associated with reef environments, inhabiting depths from 12 to 70 meters, often seen in cave openings and crevices on steep outer reef slopes. They may also be encountered singly near black corals, large sponges, or gorgonian fans. The species is diurnal and displays distinct pairing during breeding, being oviparous with demersal eggs that adhere to the substrate. Males are responsible for guarding and aerating the eggs. The Twinspot chromis is classified as Least Concern on the IUCN Red List and poses no threat to humans. It is of commercial interest for fisheries and the aquarium trade.
