Lon tentacle anemone started moving after adding new rockwork to tank.

My long tentacle anemone started moving after I added some new rockwork to my tank to house my new corals. It doesn't seem to be planting its foot and has moved up the back of the rockwork towards the back of the tank. Should I leave it be or be concerned as it has move between the glass and the rock?

Nems move around from time to time, especially if rocks are changed. Not too much you can do about it
