Goldback Damsel

Pomacentrus nigromanus

The Goldback Damsel is a small reef fish, reaching a maximum length of 9 cm. It has a fusiform body shape with an oval cross-section, characterized by its distinctive dorsal fin with 13 spines and 13 to 14 soft rays, and an anal fin with 2 spines and 14 to 15 soft rays. This species is found in the Western Central Pacific, inhabiting regions such as Indonesia, the Philippines, Palau, Western Australia, Papua New Guinea, New Britain, the Solomon Islands, and Vanuatu. Goldback Damsels are typically associated with lagoon and seaward reefs, preferring sheltered clear water reefs at moderate depths. They are most commonly encountered at depths shallower than 40 meters, with a significant number being found at depths less than 30 meters. These fish are diurnal and non-migratory, feeding on a diet that includes planktonic crustaceans, fish eggs, algae, and small invertebrates. Reproduction in Goldback Damsels is oviparous, with distinct pairing during breeding. The eggs are demersal, adhering to the substrate, and are guarded and aerated by the males. The species is assessed as Least Concern on the IUCN Red List.
