Mauritian Gregory

Stegastes pelicieri

The Mauritian Gregory is a damselfish found in the western Indian Ocean, specifically around the islands of Mauritius and Réunion. Divers can spot this species at depths ranging from 2 to 20 meters, where it inhabits rocky reefs. These environments are characterized by minimal coral presence but offer plenty of holes and crevices, which the fish use for shelter. The Mauritian Gregory is generally solitary and can be identified by its brown to charcoal or blackish coloration, with dusky gray lips and a narrow golden margin around the pupil. Its scales have blackish margins with bluish centers, especially noticeable on the suborbital series and opercular bones. In terms of size, the Mauritian Gregory can grow up to 14 cm in total length. The fish's body is short and deep, with an oval cross-section. It has 14 dorsal spines and 14 to 16 dorsal soft rays, along with 2 anal spines and 14 to 15 anal soft rays. This species is oviparous, meaning it lays eggs that adhere to the substrate. During the breeding season, males are responsible for guarding and aerating the eggs. While the Mauritian Gregory has not been evaluated for conservation status by the IUCN, it poses no threat to humans. Divers encountering this species can expect to see it alone, often near crevices or holes in the reef. Its non-migratory nature means it can be observed year-round in its native habitat.
