I have one of those branches made of thick grapevine in my BP's tank. He likes to climb up onto it... and fall off. I've watched him fall off multiple times and he doesn't seem hurt and usually gets right back up on the branch. He falls at most 6 inches down off the branch onto his aspen substrate. He's young and I can't imagine he'd it the ground hard, as he weighs next to nothing. Could he eventually hurt himself falling off? Should I take his branch out?
