I've heard before that male BPs like to climb more than females. Is this true? I'm kind of starting to believe it, seeing as my one male BP is always climbing in his tree and reptile hammock. Also, every morning when i get up and check his tank he has, without fail, created an entire underground tunnel system underneath his aspen. Is this normal?! I've just never seen or heard of any other BP doing this; i've also heard that BPs DON'T like to climb. Did i get a weird one?
