Green Lunar Wrasse

Overview

The Green Lunar Wrasse is a bright green-to-blue fish with a distinctive yellow crescent-shaped tail marking, growing into a robust, active fish that needs considerably more swimming room than its attractive juvenile colouration might suggest. It's a hardy, adaptable wrasse well suited to larger fish-only or lightly stocked reef systems.

It's also useful for pest control, since it will actively hunt and eat pest flatworms, bristleworms, and small nuisance crustaceans, making it a popular choice for keepers dealing with an outbreak, though this same hunting instinct means it can also eat beneficial small invertebrates like feather dusters, small snails, or ornamental shrimp.

Given its adult size and active nature, it's best suited to a larger, well-established tank rather than a small or nano reef system.

Compatibility

Green Lunar Wrasses can be semi-aggressive, particularly toward other wrasses of similar size and shape, and may become territorial as they mature, so introduction order and tank size matter. They generally coexist well with tangs, angelfish, and other robust community fish.

This species is rated reef safe with caution — while it won't touch stony or soft coral, it will actively hunt small crustaceans and worms, posing a risk to ornamental shrimp, ornamental worms, and ornamental small snails in the display.

Health & quarantine

This is a hardy, adaptable wrasse with few chronic health issues, though like most wrasses it's a capable jumper, so a secure lid is important. A minimum four-week quarantine is recommended good practice, and this species generally acclimates and feeds well without major issues.
