Care
Peacock Wrasses are relatively hardy and can adapt to life in captivity if provided with a well-structured environment that mimics their natural habitat. They require a tank with plenty of live rock for hiding and foraging, as well as open swimming spaces. A sandy substrate is also important for their well-being, as they often bury themselves in the sand when sleeping or feeling threatened. A varied diet of meaty foods, including frozen mysis shrimp and brine shrimp, will help maintain their health and coloration.
Reproduction
In the wild, Peacock 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 Peacock Wrasses can be challenging due to their complex social and mating behaviors.
Habitat
Peacock Wrasses are 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 at depths ranging from shallow waters to about 30 meters. They are commonly seen darting among the corals and rocks, searching for small invertebrates to eat.
