They CAN move. They have a few methods of locomotion. 1st, they burrow in the sand and can move from place to place through a tunnel network under the substrate. 2nd, they are very bouyant and can dislodge from their tubes, if they are unhappy, and go floating around the tank untill they find a new home (this is a good time to have sponges on the intakes of powerheads). If they are in a good location and are fed enough, they don't seem to wander much, but they are certainly capable of it.
