Common name: White damsel

General information

The Dusky Gregory, scientifically known as Dischistodus perspicillatus, is a species of damselfish that is less commonly seen in the aquarium trade compared to its more colorful relatives. This species is known for its more subdued coloration, typically exhibiting a pale grey to brown body with a distinctive dark spot at the base of the pectoral fin. Juveniles may have a more pronounced coloration with blue edges on their fins.

Care

Dusky Gregorys are hardy fish that can adapt to a variety of tank conditions, but they do best in well-established aquariums with plenty of live rock for hiding and grazing. They can be territorial, especially towards conspecifics, so it's important to provide ample space and structure to minimize aggression. A varied diet of meaty foods, algae, and high-quality prepared foods will help maintain their health.

Reproduction

Like many damselfish, the Dusky Gregory is an oviparous species, with females laying adhesive eggs on a flat surface, which are then guarded and aerated by the male until they hatch. Breeding in captivity is possible but not commonly reported due to the species' less prominent status in the hobby.

Habitat

Dischistodus perspicillatus is found in the Indo-Pacific region, from the eastern coast of Africa to the central Pacific Ocean. They inhabit shallow, coral-rich areas and lagoons, often associating with stony and soft corals. They are typically found at depths ranging from just below the surface to about 15 meters.
