I keep my (approximate) 2 foot BP in a 10 gallon and she is as happy as a lark. All she really cares about doing is snoozing in her half-log hide but she most definitely comes out at night and takes a dip in one of two of her water dishes, lays on her rock stack, or cuddles up next to the heating pad (side-mounted). I keep the temp around 88 during they day and around 80 at night. And the humidity is anywhere from 55-70 (depending on if it's shed time or not). This works for Mas, but I'm sure she'd be happy with any size tank if it had somewhere to hide. I'm not an expert, just as hardly anyone else on here is an expert. To whoever originally posted this thread, remember that just because some people on here have "elite" member statuses, doesn't mean they know everything. I don't know about this forum, but on others the more you post the "higher" your status gets. More posts don't make your knowledge better, necessarily. Listen to what the moderators and administrators say above all, and of course to those who have owned herps for many years. I've own LOTS of animals in my life but that doesn't make me a dog, cat, rat, or fish expert. Apologies to anyone who may get offended, but it's ridiculous that no matter what forum I go on, there are always those who repeat what's already been said a dozen times, and it makes the poster feel inadequate. If one person already said "your tank is probably too big" can't we not say it 12 more times?
