Halichoeres melanurus
A wrasse with beautiful blue-green stripes. Eats pests like flatworms and bristleworms.
The melanurus or tail-spot wrasse (Halichoeres melanurus) is a western Pacific reef wrasse, marked with fine longitudinal stripes over blue-green and growing more vivid with age. Adults reach 10-12 cm. It buries in sand at night and when startled, so a fine sand bed of 5 cm or more is needed. It is well regarded as a clean-up fish for reef tanks, preying on coral-eating flatworms, bristle worms and small pest snails. It is hardy, feeds readily and swims actively, giving the tank movement. The flip side is that small shrimp and juvenile snails are also fair game, and it jumps readily — a lid is essential.
The Melanurus Wrasse lives 5-8 years.
The Melanurus Wrasse grows to 10-12cm.
The ideal temperature for the Melanurus Wrasse is 24〜26℃.
