I have a pink tipped anemone that has been in my tank for going on 5 months now. However, within the past two days he looks like he has been twisted and he looks like he is being eaten from within. His color is also darker than normal. My nitrates, nitrites, ammonia, and pH are all within normal parameters but I have done an emergency water change just in case. Everything else in the tank seems to be doing fine. Unfortunetly I don't have a digital camera to post a picture of him. Thanks in advance for any help.
