does anyting eat berghia nudibranchs?

[atlantisaquari]

i was hoping someone has had experience with the aptasia eating berghia nudibranchs in a tank with wrasse or anything else that might eat the little buggers. i am considering getting some and dont know if they will just be eaten right away.
thanks.

and peppermints would not be an option as they would be eaten by the wrasses.
