Datasheet

General Description

Cirrhilabrus lunatus, also known as the Moon Wrasse, belongs to the Labridae family and is characterized by its vibrant and varied coloration. These fish are typically peaceful but can display aggression towards closely related species. Male Moon Wrasses can change color during courtship, showcasing a dazzling display. They are known to sleep between rocks in a protective mucus cocoon.

Aquarium Suitability

Moon Wrasses are generally suitable for most aquarium setups but may require careful consideration when selecting tankmates due to potential aggression. It is recommended to keep them in a pair with one male and one female or one male with several females. These fish may jump out of open aquariums, so a secure lid is essential. They require a tank of at least 400 liters, preferably larger, and ample hiding spots among live rocks.

Demands, Care, and Hardiness

Characterized as having an average hardiness, C. lunatus thrives in aquariums with stable water conditions. They are sensitive to transportation and acclimatization processes, requiring a cautious approach when introducing them to a new tank. Moon Wrasses are shy and docile, necessitating careful consideration when housed with more aggressive species. With a varied and high-quality diet that includes small crustaceans and zooplankton, these fish should be fed multiple times a day.

Reef Suitability

Reef enthusiasts appreciate C. lunatus for its reef compatibility, as it is considered reef-safe. These wrasses can aid in controlling populations of unwanted invertebrates commonly found in reef tanks.

Aquarium Setup

When setting up an aquarium for Moon Wrasses, it is crucial to provide them with ample swimming space. Incorporating hiding spots within live rocks will help these fish feel secure. Maintaining water parameters within the ranges of 8-12 dKH, 8.1-8.4 pH, 1.020-1.025 salinity, and a temperature range of 22.2-25.6°C is essential for their well-being.

Behaviour

• C. lunatus exhibit shy and docile behavior, but males can be territorial with each other.
• These wrasses can change gender from male to female and vice versa.
• Considered sensitive during transportation, Moon Wrasses benefit from a stress-free acclimatization process.

Feeding and Diet

Moon Wrasses thrive on a diet consisting of small crustaceans like krill and mysis, as well as zooplankton such as Cyclops and pods. Providing a varied diet is essential for maintaining their vivid coloration and overall health.

Dimorphism and Captive Reproduction

Male Moon Wrasses can change color and flash their hues during courtship displays. They may exhibit distinct color variations based on origin, making gender identification challenging. These fish may also change gender, contributing to the complexity of captive breeding efforts.

Habitat and Distribution

• C. lunatus is predominantly found in the waters of Japan and the Central/West Pacific region.
• In the wild, Moon Wrasses inhabit coral reefs and rocky areas where they can find suitable hiding places and forage for food.
