I have had my color tube anemone for a year and a half now. He would always spend 2-4 hours a day hidden in his sack, the rest of the time he would always be out. For the past two days now he has not come out of his sack. I have not made any changes in the tank, and all the readings are fine. I am not sure if he is dead, however, I do think he is in the sack, and have not seen any arms floating around. Any thoughts?
