Picked up some substrate today

Today I convinced my mom to take me to the local petshop. I picked up a block of coconut chips/fiber, its suposed to hold humidity well. Will this work for a bp?

yup coconut works well, good choice :)
Just make sure you feed in a seperate enclosure so he doesnt end up eating any substrate which can cause impaction.

Yeah, I'm thinking of buying a small rubbermaid to serve that purpose.
