No post so I thought I would start one. I like the new forum categories.
This is normal. My maroons stir up a sand storm also. Others have posted about other clowns species doing the same. I don't remember anyone ever commenting as to why though. As far as the anemone, I have heard that maroons are the roughest on or most aggresive in an anemone. For the anemone's sake, I have heard it recommended that it be 2-3 times as wide as the clown is long.
