The Yellow Fin Fairy Wrasse, Cirrhilabrus flavidorsalis, also known as the Yellowfin Fairy Wrasse and the Millennium Wrasse, has a characteristic bright yellow dorsal fin, a luxuriant pink and white body, and sometimes can have a light blue caudal fin. Often times the white and pink body forms large stripe-like patterns giving the Yellow Fin Fairy Wrasse even more vivid colorations. This fish has the unique ability to change its color depending on its mood and age. Females have similar colors and patterns with the addition of a spot near the anal fin.
