Anemone dark & shriveled tips

[WhiteRaven]

This anemone had been in my tank for a few weeks now. It always looked good (large with fill tentacles) but would move reach night. Last couple of days it had looked like this (see picture) dark, smaller, and some shriveled looking tentacles. Should I be concerned?

Does not look too bad. Anemones do weird things often. If it is moving a lot it is not happy though. I have not used Kessils, but that setup does not seem unusual. In my experience, anemones do like some Phosphate, but not sure that would cause a major problem. How is the flow in the tank? How is it in the spots the anemone seems to like or dislike?

If an anemone moves a lot I usually think lighting or flow.
