Common name: Adorned wrasse

General information

The Adorned Wrasse, scientifically known as Halichoeres cosmetus, is a vibrant and active fish that adds both color and dynamism to a saltwater aquarium. This species is part of the Labridae family, which is known for its hardy and beneficial members in the reef aquarium community. The Adorned Wrasse is distinguished by its striking coloration, which includes a greenish body with pink to red stripes and spots, and a yellow tail. Juveniles and females typically have a different color pattern compared to males, which can display more intense colors and patterns as they mature.

Care

Adorned Wrasses are relatively hardy and adaptable to aquarium life. They require a well-established tank with plenty of live rock for hiding and foraging. A sandy substrate is also important as these wrasses will often bury themselves in the sand when they feel threatened or during the night. They are known to be jumpers, so a tightly fitting lid or screen is essential 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, Adorned Wrasses are protogynous hermaphrodites, meaning they are born female and can change to male if the dominant male is no longer present. Breeding them in captivity can be challenging, and there is limited information on successful captive breeding. However, providing a stress-free environment with plenty of hiding places can encourage natural behaviors.

Habitat

Halichoeres cosmetus is native to the Indo-Pacific region, particularly around the Maldives, Sri Lanka, and the Andaman Sea. They are typically found in coral-rich areas and lagoons at depths ranging from 1 to 20 meters. In the aquarium, replicating their natural environment with a mix of coral and rockwork can provide a suitable habitat for these wrasses.
