The Moon Wrasse (Thalassoma lunare) is a popular choice for marine aquarium enthusiasts seeking a lively and visually striking fish. Known for its vibrant colours and dynamic swimming behaviour, this species adds movement and interest to reef tanks.
Care Level: Moderate to advanced. The Moon Wrasse requires stable water conditions and a well-established aquarium.
Temperament: Generally peaceful but can be territorial towards conspecifics or similar species. Best kept singly or in a large tank with plenty of hiding spaces.

Minimum Tank Size: 120 litres (approximately 30 gallons) to provide ample swimming space and territory.
Reef Compatibility: With Caution. While generally reef safe, Moon Wrasses may prey on small invertebrates such as shrimp and small crabs. Monitor interactions carefully in reef setups.
