They are algae eaters, like most tangs, but will eat all other common aquarium foods. They get big and they can be agressive as well. It is easier to find a juv then an adult because the juv are easier to ship. The juv are yellow and as they grow they become the deep blue except for the tail. At this point it is my favorite age, the tail is still yellow and they look like a red sea purple tang, just less purple. After that the tail changes and you get the adult color. If you get one it should probably be the last fish you add, as they can be hard on new introductions.
