Halichoeres

Halichoeres hartzfeldii

(Bleeker, 1852)

Hartzfeld's Wrasse

Not Reef Tank Suitable

Likely Fish-Only Tank Suitable

Range: Indo-West Pacific Ocean: Indonesia to Southern Japan.

Size: 7 inches (17 cm)

Natural Environment: Inhabits sandy and rubble areas on seaward reefs and usually found at depths between 30 – 200 feet (10– 60 m) where it feeds mainly on crabs, snails, worms, shrimp, urchins, and small fishes.

General Husbandry: Rarely seen in the trade with the male having a mottled green body with irregular pale green lines on the face and reddish pink marks on the body. Females are generally an overall white with a single yellow lengthwise band along the lateral line.

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 smaller fishes by first bashing them against hard objects, then consuming the pieces. It may also consume snails, tubeworms, sea stars, cucumbers, urchins, crabs, and shrimp, also bashing them, if needed, to be consumed.

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.

Colors tend to fade in captivity.
