Chaetodon citrinellus, the Citron Butterfly, is somewhat common throughout the Indo-Pacific but is rare in Hawaii. I consider myself fortunate to have seen one of these and, of course, it's always an event when I spot a new fish, bird, or critter. It's even more exciting when I manage to take a clean picture of it as well! This was at Queen's Surf at about 4 feet depth.
