Remember go by the largest section or weight of your bp.how old is he? I am going to guess under a year. If I'm wrong sorry. You can also get rat hoppers as I call them if they are appropriate sized. They are just like mouse hopper just in rat size lol. I have hodes on BOTH sides of my cage. Plus the water dish in the center is a kind of hide. My girl goes on all of them or she will sit and look out her "window" area lol. She's been a lot more active last couple days so I need to get her some food. I personally would never house an adult bp in a 10 gallon. 20 long atleast and that is what I start hatchlings in with a lot of appropriately sized hides. I will also cover the outside completely for a while till it got acclimated and relaxed. Good luck in what ever you decide.
