Wow didn't expect so many replies so quick! Thanks for the tips...I thought the rat was a little big. I'll go a size smaller in a week. He/She seemed to calm down after eating and is now inside the hotside hide. I leaned the black tagboard I bought at walmart up against the side for now, I didn't want to disturb him much at the moment so I'll fasten it good when hes comfortable. I actually took all the sticky backing off all the gauges because I didn't feel comfortable with that inside the tank and just hot glued everything.
