Care

Red-vented Fairy Wrasses are relatively hardy and adaptable, making them suitable for both novice and experienced aquarists. They thrive in well-established aquariums with plenty of live rock for hiding and foraging. A varied diet of meaty foods, such as mysis shrimp and brine shrimp, supplemented with high-quality marine flake or pellet food, will help maintain their vibrant colors and overall health.

Reproduction

In the wild, Cirrhilabrus rubriventralis forms harems consisting of a dominant male and several females. In captivity, they may spawn if the environment is stable and well-maintained. The males perform elaborate courtship displays to attract females. If spawning occurs, the eggs are pelagic, meaning they float with the currents until hatching.

Habitat

Native to the Western Pacific, particularly around the Coral Sea, the Red-vented Fairy Wrasse is found in coral-rich areas of lagoons and outer reefs. They prefer environments with moderate to strong water movement and are typically observed at depths ranging from 5 to 35 meters.
