Both pictures were fantastic... But I had to vote for the kole tang for the simple reason that fish are just so much more challenging to get a good photograph of. Corals (and tube anemones) kinda just sit there, waiting for their picture to be taken. You really have to work hard to get a good fish picture! And then, only one out of every 30 you take will be halfway decent -- the rest will be blurry, or have a smudge on the glass, or the fish will be halfway behind a rock...
