Care

Katoi's Fairy Wrasse requires a well-established aquarium with plenty of rockwork and caves for hiding. They are peaceful fish that do well in a community tank but may become territorial with other wrasses. A varied diet of meaty foods, such as mysis shrimp and brine shrimp, supplemented with high-quality marine flake and pellet food, will help maintain their health and coloration.

Reproduction

Like many wrasses, Cirrhilabrus katoi are protogynous hermaphrodites, starting life as females and potentially changing to males if the dominant male is removed. They exhibit fascinating courtship displays, where males flash their colors and perform a dance to attract females. Breeding in captivity is challenging but possible with the right conditions and expertise.

Habitat

Native to the Western Pacific, particularly around the Philippines, Katoi's Fairy Wrasse inhabits coral-rich areas of lagoons and outer reef slopes. They are typically found at depths ranging from 5 to 30 meters, where they swim in small harems consisting of a single male and several females.
