My tomato frog has been quite active at night lately. He was recently placed into a taller enclosure, and has been enjoying the new space by stalking around at night. However, he seems to be preoccupied with reaching along the sides of the tank, even jumping and smacking into them. He has also been jumping up over a foot to hit the glass top of his enclosure (maybe he is interested in the Exoterra Moonlight bulb?). Don't get me wrong: I'm thrilled that my frog has been active at night. However, I'm worried about the darn frog hurting itself.

Should I be concerned? Is there anything I can do about this? I thought about getting a scenic wallpaper to put on the back and right side of the tank to make him aware of the barrier, but that would not address the ceiling issue.
