there are things that you should consider in the future, after you get your new light and tank.
I understand many people suggested here to move the anemone to higher ground. In my exp with them, that is very bad to do especially if you anemone is stick to the LR
/rubble etc. It would just do it more harm then help. The stress of moving it around is not ideal. You have to allow it to move by itself as it will choose the best location it "thinks" it can survive. I just like many other ppl that always want to anemone to at where I want it to be. But it will never happen, the more I move it, they more it moves, even behinde rocks where it getting 0 lights. I would suggest to let it be once you get your new light and tank set up.
