We just purchased our anemone on 11/9. All of our tank specifications for an anemone are met. It's got a "belt" of stuff. Should I try to remove it? It's been in the corner lifeless for 2 days. I've read all over the internet that this is what they do. But, what if he's dying? What if we leave his alone so long he dies? How do I tell the difference? And sadly, in this photo it looks like it's mouth is open more wide than a couple days ago.
