In the wild, Bluehead Wrasse are found on reefs and non-reef areas of the Caribbean Sea and the tropical Atlantic at depths of 10 to 130 feet. They are very active and goes through extraordinary color changes from juvenile to adult.
They are easy to keep but they are sensitive to poor water conditions so frequent water changes is a must to keep water quality as high as possible. The ideal aquarium will have a good water filtration and plenty of swimming room with rocks where they can hide and sleep. It will also sleep in the sand sometimes so provide some.

Juveniles and females are peaceful and can be kept in group and with other fish. Adult males become territorial and aggressive. They should be added as one of the last fish and kept with larger and belligerent fishes. They will eat small invertebrates, snails, serpent stars, bristleworms, mantis shrimps and very small fish.
