Healthy anemone but mouth wide open

[Pennywise the Clown]

My bubble tip has been in my display for roughly a year. In that time it had quadrupled in size.
A couple of weeks ago in retreated into the rocks and split. It has now come back out to it's original position but its mouth is wide open.
Other than that it looks very healthy. Any ideas?

It looks healthy. I would try feeding it and seeing if the mouth will close over the food. Is it sticky?

Yes, it is still sticky.
I will try feeding it. Thanks.

It’s probably trying to poop. I wouldn’t try and feed it. Feeding isn’t a good response if something isn’t doing well. I understand the semi logic of if it’s healthy it will eat, but things don’t tend to want to eat when not looking so hot.
