Common name: Crescent-tail wrasse

General information

The Lunate Fairy Wrasse, scientifically known as Cirrhilabrus lunatus, is a vibrant and active fish that adds both color and dynamism to a saltwater aquarium. This species is part of the diverse and colorful wrasse family, known for their striking patterns and behaviors. The males of this species are particularly notable for their bright coloration and the distinctive crescent moon pattern on their tail, which gives the fish its common name.

Care

Lunate Fairy Wrasses are relatively hardy and adaptable, making them suitable for both intermediate and advanced aquarists. They thrive in well-established aquariums with plenty of live rock for hiding and hunting small invertebrates. A tightly fitting lid is essential, as wrasses are known jumpers. These fish do best in groups, with one male to several females, and should be fed a varied diet of meaty foods and high-quality marine pellets.

Reproduction

In the wild, Lunate Fairy Wrasses are protogynous hermaphrodites, meaning females have the ability to turn into males if a dominant male is not present. In the aquarium, breeding these fish can be challenging, but it is possible with a well-maintained environment and careful attention to their social hierarchy.

Habitat

Cirrhilabrus lunatus is found in the Western Pacific, from Indonesia to the Solomon Islands, and typically inhabits coral-rich areas of lagoons and seaward reefs. They are often observed at depths ranging from 5 to 20 meters, where they swim in small harems consisting of a single male and several females.
