Clown pulling off anemone tenticles

[CandyCane]

I've got a maroon clown fish thats only at most an inch long however I'm trying to introduce a rose bubble tip anemone to my tank. Right when the anemone was first in my hand in the tank the clown dove into my hand to be with it. However when I found a spot for it other anemone's have loved in the past, the anemone anchored and then the clown started rubbing on it really hard and it was like he wanted the anemone to do something. When the anemone didnt respond he started pulling legs off! WHATS GOING ON?! For now I have a net covering the BTA so the little clown cant destroy him
