The Red Clown Wrasse adults can easily grow to a foot, but in an aquarium, they rarely exceed 6-8 inches. The juvenile and adult appearances vary greatly. As a youth, the body colour is orange with white tiger stripes or spots across the back. The stripes and fins are outlined in black. In adulthood, the body takes on a speckled blue colouration, the fins are decorated with yellows, reds, and blues, and the face is orange with green stripes. The male has a light green stripe on the body, just above the anal fin.
The Red Clown Wrasse requires a 125 gallon or larger aquarium with a sandy bottom into which it will burrow to sleep, or if it is threatened. Do not attempt to keep the Red Clown Wrasse on crushed coral or similar substrate as they have a poor survival rate on such substrates. When very small, Red Clown Wrasse are safe with almost any fish that will not eat them, but as they grow, they can become destructive. They should not be kept with invertebrates.
The Red Clown Wrasse diet should include vitamin enriched frozen mysis shrimp, vitamin enriched frozen brine shrimp, and other meaty foods along with a high quality marine flake and marine pellet food.
