hey Marie,

If you have uncounted hours to sit in front of your tank..................................... you may find this helps.
I had a coral beauty that was a nipper too. I used to sit on my couch in front of tank with a broom and every time the angel went to nip, I'd tap the glass. It took a week or so, but the fish learned. Freaked out the other fish though.

Just a thought.
