Cortez Rainbow Wrasse - Thalassoma lucasanum - Juvenile

The Cortez Rainbow Wrasse, or Mexican Rock Wrasse is a very attractive wrasse. It has red, black and yellow coloration as a juvenile, which changes completely as it matures into adult form.

They prefer both open water and rocky hideouts where they can hide from predators. The natural diet of these wrasses is hermit crabs and snails so care must be taken if placed in an aquarium that contains these invertebrates. In the home aquarium they will accept frozen food, pellets and flake food. A mixture of all these foods will allow your wrasse to have a varied diet and the best nutrition. These fish can be kept one per tank but a small group is ideal for larger tanks.
