Monarch Damsel

Dischistodus pseudochrysopoecilus

The Monarch Damsel is a reef-associated fish found primarily in the Western Central Pacific, ranging from the Philippines to the Great Barrier Reef and Melanesia, with reports from Malaysia. It inhabits lagoon reefs at shallow depths between 1 and 5 meters, preferring areas with scattered live coral thickets, interspersed with sandy patches and dead coral. This species is characterized by its fusiform and compressed body shape, with 12 dorsal spines, 13 to 15 dorsal soft rays, 2 anal spines, and 14 to 15 anal soft rays. It can grow up to 18 cm in length. The Monarch Damsel is a diurnal species, meaning it is active during the day. It exhibits distinct pairing during breeding, with males taking on the responsibility of guarding and aerating the demersal eggs that adhere to the substrate. Divers encountering the Monarch Damsel can expect to find it in shallow, tropical reef environments. It is a non-migratory species, making it a consistent presence in its preferred habitats. The species is currently listed as Least Concern by the IUCN.
