I'll one up the coral revive... Try a full hydrogen peroxide dip (but not before researching it. If you have specific questions you can ask me here or pM up to you). I have tried a peroxide dip on a few of my monti's that were infested with nudibranchs a while back and in the container you could see the nudi's fall off and some looked like they started to dissolve. This isn't a casual treatment and you can easily kill the entire animal if you do it wrong, but when you absolutely, positively, must kill every possible coral issue in the room... hydrogen peroxide is my weapon of choice.
Also, I have never personally tried them with AEFW, but springeri damsels might hunt them since they are small enough to be worth the effort. Plus they just look cool and aren't a waste of tank space.
