The Powder Blue Tang is a form of coral reef fish.
"This fish is brightly colored in blue, black, white, and yellow. It has a spine where the tail joins the body that can cause injury if touched.
Native to the Indian Ocean, it is often found near coral reefs."
These are found as schools of fish, mostly in the Lagoon area. However, they tend to gather in any area that is rich in coral.
Large, slow-moving clusters of these fish can be found swimming around and above coral. They like being offered food.
