I have a great stiff foam background I made for my bp's tank, and I put in a small pvc pipe into the backdrop to give a place for the temp probe cords to run. Anyways, I panicked one day when I couldnt find him anywhere in his tank and couldnt figure out how he escaped. I finally noticed like an eighth of an inch of his tail sticking out of the bottom of the pvc pipe. I had to lure him out of the tube with a rat, and them promptly blocked the holes in the tubing.
