Not trying to argue here, but I would like to add a little helpful hint about the half log. Here's a picture of my tank setup.
I stood the log up on it's side and put some dark paper on the back of the tank, and he loves it! He's burrowed through the aspen so he doesn't have to climb over anymore, but he'll sleep in there all day. (He also chills in the other hide, in case someone says it's because he doesn't like his other hide)
I cover the sides of his tank with a towels usually at night, when we don't have the lights off, to make him feel more secure.
