Rainbow Wrasse
Veterinary & Aquatic Services Department, Drs. Foster & Smith, Inc.

The Rainbow Wrasse is also referred to as the Cortez Rainbow Wrasse or Paddlefin Wrasse. As an adult, it is a most attractive rainbow of colors, with a blue to green head, yellow neck, blue fins, blue to purple tail, and red body.

It should reside in a 55 gallon or larger aquarium with larger, aggressive tank mates, and plenty of rocks for hiding. It will become territorial and harass any new additions to the community, therefore, it should be the last fish added to the community. It may be kept with a mate if the aquarium is 75 gallons or larger. It may eat mantis shrimp and bristleworms. It does not eat corals or live plants.

Its natural diet consists of fish, crustaceans, motile invertebrates, and worms. The diet in the aquarium should include a variety of feeder shrimp, marine flesh, frozen meaty preparations for carnivores, and flaked foods.
