Might be a dumb question?

So i just came down stairs to grab something and i took a peek at my tank with all the lights off, and apparently my anemone detached from the rock on the left and is now on my glass on the right side.

What im asking is i do not have a lid on my tank, can the anemone come out of the tank??? i dont really know what to do.

Thanks a lot
Tony
