Care

Yellowfin 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 foraging. A tightly fitting lid is essential, as wrasses are known jumpers. These fish are carnivorous and should be fed a varied diet of meaty foods, including frozen mysis shrimp, brine shrimp, and finely chopped seafood.

Reproduction

In the wild, Yellowfin Fairy Wrasses are protogynous hermaphrodites, meaning they are born female and can change to male if the dominant male is no longer present. In the aquarium, breeding these fish can be challenging due to their complex social structures and the need for precise environmental conditions.

Habitat

Cirrhilabrus flavidorsalis is found in the Western Pacific, from Indonesia to the Solomon Islands, and typically inhabits coral-rich areas of lagoons and seaward reefs. They prefer depths ranging from 5 to 20 meters, where they can be seen swimming actively above the reef.

Geographical distribution includes areas such as the Coral Sea, the Great Barrier Reef, and the waters around Papua New Guinea. Their natural habitat is characterized by clear waters and abundant coral growth, which provides both food and shelter.
