I’ve had good luck with peppermint shrimp, but not all of them like eating aiptasia and they can’t reach in the smallest crevasses so they’re not a magic solution. There’s some treatment you can buy named after a dude that worked pretty well for me once the peppermints (or nudis in your case) ate most of the aiptasia, and that fixed up my problems personally.
Good luck!
