I recently found a small (3/4 or 1" disk) featherduster worm attached to a rock in a space between two rocks. Without chipping the rock (its at the bottom of the stack and touches glass on 2 sides + bottom), is there a safe way to remove the worm from that rock and attach it to another out in the open? If this is too risky for the animal I will just leave it where it is. Thanks.
