Halichoeres

Halichoeres margaritaceus

(Valenciennes, 1839)

Pink-belly Wrasse, Pearly Wrasse

Not Reef Tank Suitable

Likely Fish-Only Tank Suitable

Range: Indo-West Pacific Ocean: Cocos Island to Line and Tuamotu Islands, north to Southern Japan, and south to New South Wales and Lord Howe Islands.

Size: 5 inches (12 cm)

Natural Environment: Inhabits shallow lagoon rubble and sandy areas, yet usually found in weedy areas

General Husbandry: Occasionally seen in the trade with the average male having a somewhat mottled greenish body with pale reddish irregular lines on the face, and the female a mottled pearly colored body with a pink belly.

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, as it grows into adulthood may also eat snails, tubeworms, crabs, and 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!

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.
