Second (or third or fourth) the aspen! I bought a giant bag of aspen at the expo I purchased mine from and about 5 days later ended up buying coco husk because the aspen was a nightmare for humidity and clean up. Every breeder there recommended it and it still baffles me how they can keep bp's in our dry climate on aspen successfully.

This second point is more because Viago is my first snake and only the second one I've ever handled. I wish I knew not to be nervous right off the bat! He's small but I was still afraid he'd be defensive and strike or something as I'm used to crested geckos, whose bites (when they happen, if they ever do) are like being clamped with a weak closepin lol. But my little dude is so docile and sweet! I was honestly apprehensive taking him out of his transport cup and putting him in his cage, and when I first held him properly a week or so later. It didn't take me long to realize how silly I was being and that a bp is probably one of the more docile reptiles in the trade. And if they do bite you, it's less painful than a cat scratch/bite, which I'vew experienced many times
