Grey Damsel

Pomacentrus reidi

Pomacentrus reidi, commonly known as the Grey Damsel, is a small reef fish reaching a maximum length of 9.0 cm. It has a compressed body with a short and deep shape, characterized by 13 dorsal spines and 13 to 15 dorsal soft rays, along with 2 anal spines and 15 to 16 anal soft rays. This species is typically found in the Indo-Pacific region, ranging from the Philippines and Celebes to the Solomon Islands, Vanuatu, and the Great Barrier Reef, including Palau in Micronesia and the Mentawai Islands in Indonesia. The Grey Damsel inhabits tropical marine environments, preferring steep outer reef slopes and deep lagoons at depths between 3 and 70 meters. However, most individuals are found shallower than 40 meters, with a significant number residing at depths less than 30 meters. These fish are generally solitary, often seen among large rubble pieces or at the bases of large corals. They are diurnal and exhibit distinct pairing during breeding. The species is oviparous, with males taking on the role of guarding and aerating the eggs, which adhere to the substrate. Divers encountering the Grey Damsel may find it amidst coral rubble, where it can be relatively stationary. The species is classified as Least Concern by the IUCN.
