My anemone recently dislodged itself from it's normal perch and is lying on it's side on the tank floor. It tentacles have turned lime green and are usually deep purple and a mojority of them are just hanging and not moving. The base of the anemone is bright orange and has not changed color. However, it has shrivelled up into a little ball and is not moving. My clown fish no longer goes near it or uses it for companionship.
