I have had an anemone for 3 weeks now and it was doing fine up until a couple of days ago. It looks like a snail that is decaying. I have moved it to a spot with better flow and it looks like it is slowly getting worse. I have no idea what to do now. I am not sure if there is any sort of supplements I can add to help. I have tried to feed it with no luck. any help is appreciated. I have attached pictures below of the slow progression hopefully a full recovery.
