Anemone not happy

[fishRus]

My bubble tip anemone is two years old now it does not expand like it used to all my corals - hard and soft seem happy. My my female maroon clown has grown pretty large and is always swimming in and out. The anemone did eat a piece of shrimp about a week ago it is not eating like it used to
Anyone have any ideas?

It looks pretty healthy to me. Years ago people talked a lot about allelopathy, and I do see you have a robust haddoni nearby. I wonder if that could be an issue?

Actually that is a toadstool mushroom leather coral
My anemone hasn’t been expanding enough to come in contact with it

Oh, looked like a carpet anemone. Either way, some people suspect chemicals released from other anemones/corals sometimes has a detrimental effect. The solution suggested generally is granulated activated carbon and protein skimming. The jury seems to still be out just how much allelopathy occurs.
