Halichoeres melanurus (Tail-spot wrasse)

Overview

  • Native to the Indo-Pacific, commonly found in coral reefs, lagoons, and seagrass beds.
  • Recognized for its vibrant green and blue body with striking orange and yellow patterns.
  • A highly active swimmer, frequently seen darting through rock formations and sandy bottoms.
  • Juveniles display more subdued coloration, which intensifies as they mature.
  • Popular in reef aquariums due to its pest control abilities, including eating bristle worms and flatworms.

Feeding

  • Carnivorous diet, primarily feeding on small crustaceans, copepods, and polychaete worms.
  • Readily consumes frozen and live foods such as mysis shrimp, brine shrimp, and chopped seafood.
  • Can be trained to eat high-quality marine pellets and flake foods.
  • Requires multiple small meals throughout the day to maintain energy levels.
  • Enjoys foraging in the sandbed for hidden prey, mimicking natural hunting behavior.

Habitat

  • Typically found in shallow reefs and sandy coastal areas.
  • Requires an aquarium with open swimming space and a fine sand substrate for burrowing.
  • Best kept in tanks with live rock formations to provide shelter and hunting grounds.
  • Moderate to strong water flow is recommended to replicate natural reef conditions.
  • A minimum tank size of 75 gallons is recommended due to its active nature.

  • Requires stable water conditions and consistent tank maintenance.
  • Can be sensitive to sudden fluctuations in salinity or temperature.
  • Regular sandbed maintenance is crucial, as it burrows at night for protection.

Compatibility
