Timor Wrasse

Timor Wrasse

The Timor Wrasse (Halichoeres timorensis) is a hardy, busy little reef wrasse marked with fine lines and spots over a pale-to-greenish body, brightening with maturity. Like other Halichoeres, it is constantly on the move, hunting small invertebrates over and within the substrate, and it shares the genus's useful habit of eating pest species. Active, reef-safe and undemanding, it is a good choice for a community reef.

It dives into the sand to sleep and to escape danger, so a soft sand bed is part of its care.

Natural Habitat & Origin

Halichoeres timorensis is found across the Indo-Pacific, where it ranges actively over reefs, rubble and sandy areas, hunting small invertebrates on and within the substrate. It buries in the sand at night and when threatened.

In the aquarium it wants open swimming space, live rock with crevices, and a fine sand bed it can dive into.

Care Requirements

Maintain stable marine conditions: salinity around 1.024–1.026, pH 8.1–8.4, and a temperature of about 24–26°C (75–79°F). Reaching about 12 cm (5 inches), it suits a tank of around 115 litres (30 US gallons) or more with a fine sand bed and plenty of rockwork. A secure, gap-free lid is essential — wrasses are accomplished jumpers. It is hardy and adaptable, an excellent beginner wrasse.

Diet & Feeding

The Timor Wrasse is a carnivore, feeding on small crustaceans and invertebrates in the wild — including pest species, which makes it useful in a reef. Offer a varied diet of frozen mysis and enriched brine shrimp, finely chopped seafood and quality marine pellets, fed once or twice a day. It is an active, enthusiastic feeder.

Behavior & Temperament

This is a generally peaceful, active fish that mixes well in a community, though it is a busy swimmer that can outpace shy tankmates at feeding time. It is best kept singly unless the tank is large. It spends its day ranging over the rocks and sand in search of food, diving into the substrate to rest.

Tank Mates

Good companions are a wide range of peaceful to semi-aggressive reef fish — clownfish, tangs, gobies, other (dissimilar) wrasses and similar. It is reef-safe with corals and ornamental invertebrates, though as a small predator it may eat tiny shrimp along with pest species such as bristleworms and pyramidellid snails — often a welcome trait in a reef.

Breeding

Halichoeres timorensis is a protogynous hermaphrodite and pelagic spawner; rearing the larvae is beyond the home aquarium, so trade specimens are wild-collected.

Common Health Issues

The Timor Wrasse is hardy but, like all marine fish, can be affected by marine ich (Cryptocaryon irritans) and marine velvet (Amyloodinium ocellatum), particularly when stressed. Quarantine new arrivals, keep water quality stable, provide a sand bed for sleeping, and secure the lid against jumping. Given those basics it is a hardy, active and useful wrasse — and an excellent beginner choice for a reef.
