the clown is trying to keep the anemone from getting sand in it. My maroon clears the sand away from my anemones and they are not on the sand bed, they are about 3 inches above it. Maroons are especially hard on anemones, so good luck. Ive had 2 different anemones, the first one the clown killed being to rough with it, the second i learned my lesson and got a little larger GBTA and it is doing great and has split twice.
