I'd skip out on the tank setup also if your new to BP's, i've only been into the "hobby" for a few months, had i known how hard it can be to regulate temps and humidity through the entire aquarium, i'd skipped out on it from the start. 2-3 weeks of having an aquarium and i was done with it. Broke down and ordered a small rack system, with a quality tstat. Its overall better this way for both me and my snakes, less stress, less worrying and constant checking of temps. Already added 2 additional snakes within a month, harder to do with an aquarium, ordered a 2nd rack system and planning on more purchases of BP's already(just waiting on new rack to be built and arrive now).
You'll probably want another anyways like everyone else lol
