Halichoeres

Halichoeres cosmetus

Randall & Smith, 1982

Adorned Wrasse

Not Reef Tank Suitable

Likely Fish-Only Tank Suitable

Range: Western Indian Ocean: South to Natal South Africa.

Size: 5 inches (12 cm)

Natural Environment: Inhabits shallow coral and rocky reefs and usually found at depths between 6 – 100 feet (2– 30 m) where it feeds mainly on crustaceans.

General Husbandry: Rarely seen in the trade having orange horizontal stripes on a greyish green body, with the female having two black eyespots on the dorsal.

Best maintained in fish-only aquariums having a fine sand bed, (0.5 – 2.0 mm) and at least 4 inches deep, along with several rocky crevices to hunt and also open swimming areas. Those in this genus will not only rearrange bottom dwelling corals in its search for tasty bottom dwelling invertebrates, it may also consume snails, tubeworms, crabs, and ornamental shrimp.

It will also quickly burrow into the sand bed if frightened or for sleeping at night. This diving into the sand bed will cause clouds of sand particles to be dispensed into the water, and would cause various corals harm, therefore, those in this genus, depending upon their size, are not often recommended for reef aquariums.

Requires a meaty diet, including fortified brine shrimp, mysis, and other meaty type marine-based frozen or fresh foods, and should be fed twice daily.

Taxonomy:

    Order: Perciformes

    Suborder: Labroidei

    Family: Labridae

    Genus: Halichoeres

FYI: Upon first entering the aquarium may stay buried for days. Simply await its decision when to emerge. Once established, it will go to sleep under the sand and arise the next morning at almost the exact same time every day!

Generally peaceful as a juvenile, yet as it grows into adulthood, may pick on passive smaller tankmates.

The aquarium should have small pieces of rocks for the wrasse to ‘play’ with in its daily search for prey.

Can greatly stir bottom sandbeds creating large clouds of sand being dispensed in many directions.

One male per aquarium.
