Any idea what this is?

There is a hole in the center of my Xmas tree rock. Something in there is constantly moving around but never comes out. It looks like it might have antanaes or something.

Is it the thing on the right side of the rock, under the GSP? What little I see of it, it looks like a stomatella snail, but not sure. Try to look at it at night after the lights are out and see if it is out roaming around.

No its the Giles right in the. Middle of the rock the Xmas tree worms are on. If u look at it u can see something moving around in there.

Oh, ok now I see what you are talking about. My guess would be a bi-valve and you see it opening and closing.
