anemone and button polyp

[saxerphoner]

I have an atlantic anemone that has made his way a little too close to my button polyps. The anemone's tentacles are brushing against the polyps and causing them to close up and his tentacles to shrink up... are they stinging each other? Also, should I take measures to keep them seperated? It looks as though the anemone is trying to go the other way but it's just not that fast

Thanks for any advice!!!!
