1. The tank would probably last you about 2 years; until she was 36 inches thereabout.
2. I'm sorry but I really don't know.
3. I have one and it works just fine.
4. I don't know because I don't use heat lamps; they aren't necessary.
5. Enough to fill about 1-2 inches substrate.
6. I like exo-terra reptile caves because the snake fits snugly inside. Your bp needs a hide small enough that she/he fits snugly.
7. That isn't required because bp's aren't really climbers, but if you have the cash, go for it!
8. Good.
9. I got mine from a local Harbor Freight.
10. That'll work.
11. Some disinfecting wipes or soap and water will probably do the trick.
Good luck! Hope I helped.
