Common name: moon wrasse

General information

The Lunar Wrasse, Thalassoma lunare, is a vibrant and active fish that adds both color and dynamism to a saltwater aquarium. Known for its bright green body and striking blue and pink facial markings, this species is a favorite among aquarists. As it matures, the Lunar Wrasse develops a distinctive lyre-shaped tail, which is the origin of one of its common names, the Lyretail Wrasse.

Care

Lunar Wrasses are robust and adaptable, but they require a spacious tank with plenty of swimming room and rockwork to explore and forage. They are known to jump, so a tightly fitting lid is essential. These wrasses are not reef-safe as they tend to prey on small invertebrates and may disturb the substrate, potentially harming sessile invertebrates and corals.

Reproduction

In the wild, Lunar Wrasses are protogynous hermaphrodites, starting life as females and potentially changing to males as they grow larger and more dominant. In the aquarium, breeding is rare, but environmental stability and a well-maintained habitat can encourage natural behaviors.

Habitat

Lunar Wrasses are found in the Indo-Pacific region, from the Red Sea and East Africa to the central Pacific. They inhabit coral reefs and lagoons, often seen at depths where light penetration supports vibrant coral growth. They are active during the day and bury themselves in the sand at night for protection.
