have you spot fed it? You need to get a turkey baster, thaw some kril in a container with some of your tank water in it, and baste the anemone close to the middle, where the mouth is. If the anemone has not attatched to anything, it is not happy. If I were you, I would feed it everyday until I noticed a change, then change to every other day, then once a week and stay at that feeding. Some people do not spot feed, but you will notice a quick change if you will , especially if they are ill or weak.
