Species description

Geographical Origin and Habitat: Western Atlantic: from North Carolina to the northern Gulf of Mexico and Venezuela coasts. Found in coral reefs, shallow lagoons, and sandy margins at depths from 1 to 30 meters.

Taxonomy and Morphology: Genus Halichoeres, family Labridae. Elongated body with a pointed snout and specialized teeth for feeding on benthic invertebrates. Grows to 20.0 cm.

Social Behavior: Active diurnal swimmer that spends the day hunting near the substrate. Burrows into the sand bed at night or when threatened.

Coloration and Sexual Dimorphism: Prefers deeper reef slopes and rubble zones rather than shallow intertidal pools. Adult males possess striking, colorful patterns, whereas juveniles and females exhibit camouflaging stripes or spots.

Care, breeding and tankmates

Aquarium Setup: Requires a spacious aquarium of at least 300.0 liters with a fine sand bed of at least 5-8 cm depth for sleeping. A secure lid is highly recommended.

Diet and Feeding: Active carnivore. Diet should include mysis shrimp, brine shrimp, chopped krill, and high-quality dry pellets.

Water Quality: Keep marine parameters stable: temperature 21.0-26.0 °C, pH 8.1-8.4, specific gravity 1.020-1.025.

Compatibility and Cohabitation: Safe with corals, but may eat small ornamental shrimps, tubeworms, and flatworms. Great for pest control.

Aquarium Breeding: Protogynous hermaphrodite. Broadcast spawner; successful captive breeding in home aquariums is undocumented.

Risks and Diseases: Skin infections can occur if the sand substrate is too coarse or sharp. High jumping risk.
