We just purchased a blue spotted jawfish for our tank, and put him in a few hours ago. He immediately selected a spot a distance away from the bed of deep substrate we placed especially for him, and behind a piece of liverock. We would greatly prefer that he create his burrow in the deep part of the substrate, in better view. But we don't want to prod him into moving, only to have him choose an even more remote location (ie the back of the tank!). Is there a way to "pursuade" him to move to our desired location, before he gets too comfy?
