They get around 9 inches so about the size of a yellow tang, or a bit bigger. They are easier to feed than the coral banded but with the long sharp mouth, gotta feed appropriately sized items. And they are carnivores and use that long nose to pick at crustations and worms in the live rock. So a quality angelfish/butterfly fish diet would work. Mine ate chopped up mysid without to much fuss. It would also try the flake but didn't have a taste for it and would spit it back out. An occassional live black worm would no doubt be appreciated as well.
