Liz - The spotted drum is a definite prize-winner! Those guys are nearly impossible to nail, but you did it. My only suggestion would be to take the photo back to Photoshop or Photoshop Elements and tone down the hot whites a bit. It's fairly easy to do, and there are several approaches that work.
Your photo really is remarkable. For years, my wife and I planned our annual dive trip around the Nikonos Shootout (1986-about 1997), a series of UW photography competitions and workshops held at 3-4 locations in the Caribbean each year. On one day of the Shootout, everyone had to shoot macro or close-up. If you ever shot a Nikonos, you remember those wire framers that you somehow had to lure a fish into - an almost impossible feat! A spotted drum would win every time, if anyone was good enough to get the shot. Even with the vastly improved gear, a photo like yours is still a great shot, so go for it.
Good luck!
