Bubble Anemone on the Move

Last night I bought a green bubble anemone and placed it on a piece of live rock. I bought it while it was attached to a small piece of live rock. The owner of Beyond the Reff couldn't get it to detatch from the rock so he included the rock with the anemone. On the way home it detatched from the rock. It was a long ride home; about an hour. This morning it moved to the side of the rock. It looks like it is moving out of the direct light.
