Common name: African coris

General information

Cuvier's Wrasse, also known as the Red Coris Wrasse or Yellowtail Coris, is a vibrant and active fish that adds a splash of color to any marine aquarium. Juveniles exhibit a striking pattern of white and orange-red with black spots, which transitions into a brilliant green and blue body with a yellow tail as they mature. This species is known for its remarkable ability to change its sex from female to male, a process known as protogynous hermaphroditism.

Care

Cuvier's Wrasse requires a spacious tank with a sandy substrate to accommodate its burrowing behavior. They are known to be jumpers, so a tightly fitting lid is essential to prevent escape. This species is generally hardy but does best in a well-established aquarium with stable water conditions and plenty of live rock for grazing. They are not reef safe, as they may prey on small invertebrates and disturb the substrate.

Reproduction

In the wild, Cuvier's Wrasse forms harems consisting of a dominant male and several females. If the male is removed or dies, the largest female will often change sex to become the new dominant male. Breeding in captivity is rare, but environmental stability and a stress-free environment can encourage spawning behavior.

Habitat

Cuvier's Wrasse is found in the Indo-Pacific region, from the Red Sea and East Africa to the central Pacific. They inhabit coral reefs and rocky areas, often seen at depths ranging from shallow waters to about 60 meters. Juveniles tend to stay in shallower, protected coastal areas, while adults are more commonly found in deeper waters along reef slopes and drop-offs.
