Barrier Reef Chromis

Chromis nitida

The Barrier Reef Chromis, also known as the yellowback puller, is a small damselfish native to the subtropical east coast of Australia, including Lord Howe Island. It can be identified by its yellowish-brown dorsal surface, which is separated by a dark diagonal stripe from its silvery flanks and underside. The fish has a deeply forked tail fin with black edges and grows to a maximum length of about 9 cm. Divers can spot this species in coral-rich rocky reefs and estuaries at depths ranging from 5 to 25 meters, though it has been recorded as deep as 40 meters. This species is diurnal and often forms shoals, sometimes associating with the black-axil chromis. Its diet consists of algae, zooplankton, and small invertebrates. During the breeding season, the Barrier Reef Chromis forms pairs, with males guarding and aerating the adhesive eggs that are laid on the seabed. Divers may encounter this fish in midwater aggregations, where its non-aggressive nature allows it to mix well with other species. The Barrier Reef Chromis is classified as Least Concern by the IUCN. It is harmless to humans and can also be kept in reef aquariums, where it thrives in small groups.
