Congrats! I'd just suggest upping the prey size for next feeding. Pinkies are way small for a bp. Even hatchlings need bigger prey. Just feed your bp one rodent that's the same thickness as the girthiest part of him. Maybe a weanling or adult mouse would do.

Also, since you haven't answered it yet, and I've been wondering..what are you using at the bottom of the tank? That wood splinter stuff..never seen it before. lol
