yea i thought about the tank size when i brought the baby home, would a tank divider do the trick? idk how it can be much different. Also i dont get my having a smaller tank is superior to having more variety with more hides, more things to climb on, and everything else. and about the b-p's falling, i know it haha they always try to scale the walls and fall over, it can't hurt much though. And the vines only go about half the height of my 110
