General information

The Three-spot Wrasse, Halichoeres trimaculatus, is a colorful and active fish that adds both beauty and dynamism to a saltwater aquarium. It is known for its striking coloration, with a yellow head, white body with three black spots, and a greenish tail. Juveniles often have different coloration, which transitions to adult colors as they mature.

This species is not as commonly found in the aquarium trade as some other wrasses, but it is appreciated by hobbyists for its interesting behavior and pest control abilities, as it will often eat small invertebrates and parasites that can harm other tank inhabitants.

Care

Three-spot Wrasses are relatively hardy and can adapt to a variety of tank conditions. They require a well-established tank with plenty of live rock for hiding and hunting. A sandy substrate is also important as these wrasses may bury themselves in the sand when they feel threatened or during the night.

They are known to jump, so a tight-fitting lid or screen is necessary to prevent escape. A varied diet of meaty foods, including frozen mysis shrimp, brine shrimp, and quality marine flake and pellet foods, will help maintain their health and coloration.

Reproduction

In the wild, Three-spot Wrasses are protogynous hermaphrodites, meaning they start life as females and can change to males if the dominant male is no longer present. Breeding them in captivity can be challenging due to their complex social structures and the need for precise environmental conditions.

Habitat

Halichoeres trimaculatus is found in the Indo-Pacific region, from the Red Sea and East Africa to the central Pacific. They are typically seen in shallow, coral-rich areas and lagoons, often at depths of 1 to 20 meters. They are active swimmers and are often observed darting among the corals and rocks in search of food.
