I hope this is OK - but there is the most amazing slideshow by Greg Rothschild, a professional wildlife photographer who has a passion for reef tanks. It's from a thread on the RC photography forum.
After I kind of stumbled across it, that others might enjoy it here who maybe wouldn't stumble across it...
If you like tangs especially, you should see this - I thought it was a good deal for not having to pay admission.
