Joker is correct. If you want an anemone that won't really move or sting things you could get a flower anemone or a mini-carpet anemone if you like them. There are some beautiful colors and they will host anemone crabs, shrimp, etc, just not clowns.
Sometimes you get lucky with bubble tips and it will sit in one spot and almost never move or you can get unlucky and have one that moves 10 times a week.
