Datasheet

General Description

The Grey Head Wrasse, also known as the Threespot Wrasse, is characterized by three white lines on each side of its head, three black spots along its back, and three false "eyes" along its dorsal fin extending to a fourth on the tail in juveniles and females. Adult males of this species feature vibrant blue stripes on their faces and orange/red spots along their bodies.

Aquarium Suitability

This species thrives in a minimum 70-gallon aquarium with a secure lid, a sandy substrate of 2-3 inches for shelter, and the company of peaceful wrasses, including conspecifics. While it preys on fireworms and pyramidellid snails, it poses no threat to corals or clams. However, larger individuals may target small ornamental shrimp and crabs, as well as feather dusters, wild shrimp, tubeworms, and flatworms. The Grey Head Wrasse serves as a useful tank-mate for parasite control and should be fed a varied diet of vitamin-enriched frozen mysis shrimp, brine shrimp, marine flake, and pellet foods.

Care and Hardiness

This wrasse exhibits moderate care requirements and is generally peaceful in temperament. Maintaining stable water conditions with a preferred pH range of 8.1-8.4, a specific gravity of 1.020-1.025, and a carbonate hardness (KH) of 8-12 dKH supports its well-being.

Reef Suitability

Considered reef-compatible, the Grey Head Wrasse does not harm corals or clams, making it a suitable addition to reef aquariums.
