Common name: cigar wrasse

General information

The Rainbow Wrasse, also known as the Surge Wrasse or Reef Wrasse, is scientifically named Cheilio inermis. This species is known for its vibrant coloration and dynamic behavior, making it a popular choice among saltwater aquarium enthusiasts. The Rainbow Wrasse is a fast swimmer and an active forager, often seen darting around the reef in search of food.

Adults typically exhibit a striking combination of blue, green, and yellow hues, with males often displaying more intense coloration than females. Juveniles have a different color pattern, which includes a series of white and black vertical stripes that gradually change as they mature.

Care

Rainbow Wrasses are relatively hardy and adaptable to aquarium life, but they do require a well-established tank with plenty of swimming space and rockwork to mimic their natural habitat. They are known to jump, so a secure lid is essential to prevent escape. These wrasses are not picky eaters and will accept a variety of meaty foods, including frozen mysis shrimp, brine shrimp, and finely chopped seafood.

Reproduction

In the wild, Rainbow Wrasses are protogynous hermaphrodites, meaning they are born female and have the ability to change to male later in life. This usually occurs when there is an absence of a dominant male in the group. In the aquarium, breeding is rare, but environmental stability and a well-matched pair can increase the chances of successful spawning.

Habitat

Cheilio inermis is commonly found in the Indo-Pacific region, from the Red Sea and East Africa to the central Pacific. They inhabit coral reefs and rocky outcrops, often in areas with strong water movement. They can be found at depths ranging from shallow waters to about 30 meters.

Their natural behavior includes maintaining a territory within the reef where they actively forage during the day. At night, they retreat into crevices or bury themselves in the sand for protection.
