Halichoeres scapularis - Zigzag Wrasse

Halichoeres scapularis (Zigzag Wrasse)

Overview

  • Native to the Indo-Pacific region, commonly found in coastal reefs, lagoons, and sandy seabeds.
  • Recognized for its elongated body with a yellowish-green base color and distinctive dark zigzag patterns.
  • A highly active forager, constantly moving and searching for food along the substrate.
  • Juveniles tend to have more pronounced markings, while adults develop a deeper coloration.
  • Often used in reef aquariums to help control pest populations such as small invertebrates.

Feeding

  • Carnivorous diet, primarily consuming small crustaceans, worms, and benthic invertebrates.
  • Readily accepts 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 sustain its high energy levels.
  • Forages by sifting through sand, mimicking its natural feeding behavior.

Habitat

  • Commonly found in sandy-bottomed areas near coral reef formations.
  • Requires an aquarium with a soft sand substrate for burrowing.
  • Best suited for tanks with live rock and ample hiding spots.
  • Moderate to strong water flow is beneficial for simulating natural reef conditions.
  • A minimum tank size of 75 gallons is recommended due to its active swimming habits.

Fish Care

  • Optimal water temperature: 74-80°F (23-27°C).
  • Ideal pH range: 8.1-8.4, with a specific gravity of 1.023-1.026.
  • Requires stable water parameters and regular maintenance.
  • Can be sensitive to sudden fluctuations in water quality.
  • Burrows in the sand at night for protection, so maintaining a deep enough sandbed is essential.

Compatibility

  • Generally peaceful but may become territorial with other wrasses of similar size.
  • Compatible with other peaceful reef fish such as clownfish, tangs, and gobies.
  • Should not be housed with overly aggressive tank mates.
  • Reef-safe with corals but may consume small ornamental shrimp and snails.
  • Does best in a community tank with plenty of open space and hiding areas.

Aquarium Behavior

  • Highly active swimmer, constantly exploring its environment.
  • Frequently seen picking at live rock and sifting through sand for small invertebrates.
  • Burrows in the sand at night for protection, emerging in the morning.
  • Curious and interactive, often displaying interest in new tank additions.
  • Thrives in a well-structured aquarium that provides both open swimming space and secure hiding spots.
