One of my carpet anemones is host to a maroon clown fish. The clown constantly digs up the sand bed with his tail fin. He has created a creator around the anemone and piled the sand up about 7" deep. I can see many worm tracks and tunnels where he has disturbed the sand bed. Is this having a negative effect on the sand bed and it's inhabitants? My sand bed is mostly olitic aragonite 4" to 5" deep.
