A hardy, festively colored Halichoeres wrasse marked with red and green stripes in a holiday-like pattern, recently split from the Pacific populations of Halichoeres ornatissimus. Active, reef-safe, and valued for hunting pest snails, flatworms, and bristleworms.

Wrasses (family Labridae) are an enormous, diverse group of active, colorful reef fish ranging from tiny fairy and flasher wrasses to large predators. Many sand-diving species sleep buried in the substrate, most are accomplished jumpers, and several are prized for controlling pest invertebrates in reef aquariums.
From the minimum an animal needs to be kept humanely, up to the ideal setup. Bigger is almost always better — minimums are floors, not targets.

Life & growth stages
How this animal changes through its life — each stage often has its own care, diet and space needs.

Egg
Fish eggs are small, translucent spheres, often laid in clutches on plants, substrate, or in a nest — or carried/brooded by a parent in livebearing and mouth-brooding species. A dark eye spot and the curled embryo become visible inside as development progresses.

Fry
Newly hatched fry are tiny and semi-transparent, frequently still carrying a yolk sac that fuels them before they feed freely. They lack full fin structure and adult coloration, staying near cover until they can swim and forage on their own.

Juvenile
Juveniles look like miniature adults but with developing fins and muted or different markings; many species shift pattern and color as they mature. Growth is rapid at this stage given clean water and steady feeding.
Adult
Adults show the species' full size, finnage, and mature coloration, and are sexually mature. Many fish develop sex-specific differences in size, color, or fin shape, which can intensify during breeding.
Habitat & enclosure
Provide a minimum of 50 gallons with a long footprint for open swimming, as this is an energetic, all-day swimmer, plus a deep, fine sand bed for sleeping and abundant live rock for grazing. The sand bed is essential because the Christmas wrasse buries itself to sleep and when startled. Fit a secure, gap-free lid, as these wrasses jump.
Maintain stable tropical reef parameters: temperature 72-82 F (22-28 C), pH 8.1-8.4, salinity 1.023-1.026 specific gravity, and moderate flow. A mature reef with rich natural microfauna keeps the fish well fed and brightly colored.
Substrate
A deep bed of fine sand (at least 1.5-2 in / 4-5 cm) is mandatory, because this wrasse buries to sleep and to escape threats. Pair it with generous live rock for grazing surfaces and crevices.
Equipment & setup
Run a marine system with a protein skimmer, strong biological filtration, and a reliable heater; add a chiller in hot climates. Provide moderate flow from powerheads, standard reef lighting, and a tightly fitting lid to prevent jumping.
Diet
A micro-predator that hunts small invertebrates over rock and sand, including copepods, amphipods, pest snails (such as pyramidellids), flatworms, and small bristleworms, which makes it useful for reef pest control. In the aquarium it eagerly accepts frozen mysis and brine shrimp, finely chopped seafood, and quality marine flakes and pellets.
Feed one to two times daily; a mature reef supplements its diet with constant grazing. It is a fast, confident feeder that adapts readily to prepared foods.
Behavior & temperament
Active and generally peaceful toward unrelated tankmates, though it can become assertive with maturity, especially toward other wrasses or small bottom-dwellers. It is reef-safe with corals but, like other Halichoeres, may prey on ornamental snails, small shrimp, tubeworms, and other small motile invertebrates, so it is not fully invertebrate-safe.
Keep one per tank unless the aquarium is large, as it is aggressive toward similar wrasses. Introduce it after more timid fish are established and provide ample rockwork sightlines to diffuse territorial tendencies.
Health
Hardy and disease-resistant once settled, but vulnerable to ich and marine velvet after shipping, so quarantine new arrivals and keep parameters stable. A deep, soft sand bed is essential; without it the fish cannot bury and becomes chronically stressed.
Wrasses can be sensitive to copper, so treat cautiously. The most common keeper concern is a startled fish disappearing under the sand for a day or two after a disturbance, which is normal, or jumping from an uncovered tank.
Tips, DIY & hacks
Use this wrasse to help control pest snails and flatworms in a reef, but keep prized small snails and shrimp in mind as potential prey. Ensure the deep sand bed is in place before introduction, drip-acclimate, and quarantine first. Note the recent taxonomic split: Pacific 'ornate' wrasses are now described as Halichoeres claudia.
