I have a bubble tip anemone. It used to hide when the lights go dark. Last night, it stayed OPEN when the lights were off. Then this morning, I saw its mouth open for a while. When the lights came on, it closed its mouth. It and the tank's been moved recently, and I am concerned it might be starting to get unwell. Is it strange that anemone stayed open at night?
