Hey all, still relatively new to reefing, just recently got this bubble tip anemone two or three weeks back now. Slowly since, it has started shrinking up, revealing its mouth way more, and loosing the dense coloring on the tips/arms. I placed it in a nice spot in my rocks and after moving all over the tank decided to stay on my frag rack for some reason. The past week it decided to move to the underside of the rack for some reason. I have noticed from time to time a small black string like material coming out of the mouth. Water parameters appear to be normal and all coral still doing fine. During the day the anemone just looks sad and shrinking, while at night it puffs up and looks larger/normal. I'm not entirely sure what the cause is, however I believe it could be an issue of too much lighting? Any information would be greatly appreciated, thanks all!
