My bp does that as well. Reality is, they don't seem to like glass terrariums. He will do it till I encase the enclosure in paper. Then he feels secure and goes into a hide and relaxes. The breeder I got him from recommended that I cover the sides, and uncover 1 side a week so they slowly get use to it. Mine doesn't seem to be getting use to it, so I covered the sides in paper again, and he stays in his hides again.
