Regal no longer reef safe

[Snappy]

I've had the same regal tang for over 3 years and in the last 6 weeks it has started behaving a little out of character. It has started eating my GSP which is fine because it keeps them from taking over but he has also started nipping at my clam mantles. Has anyone else had this experience and do you have any recommendations other than removal of the tang?

I picked up one in the summer that has also turned into a nipper. It nips clam mantles, and LPS, particularly open brains, but also Euphyllias & Elegance. I'm planning to try to trap it out of there.
