There's a really good FAQ section here on the forum that will answer a lot of the questions you have. As far as feeding on live, you can probably easily change to frozen/thawed mice. I've never had one not make the switch as long as it's well heated to live animal temperature. Babies do well in smaller enclosures. I keep mine in a 10 gl. tank that I had left from my other baby, but they also do great in a rubbermaid shoe box with holes punched in the top. That's what I housed three of mine in. Give your new snake at least 3 or 4 days to get used to it's new home before handling or attempting to feed. Many babies won't bite, some do, some just threaten. Of my 6 babies, 4 did not do anything and were very calm, 1 didn't bite, but tail rattled, and one has bitten, rattled and musked. If you get the chance, try to handle the snakes first and find one that isn't trying to get away quickly, but acts calm in your hand. Investigating things, but not acting frantically. I find that when they are calm when they're babies, they tend to stay that way. My amel was like that. The calmest of all the ones I handled at the show. He's always been the most laid back, the best feeder, and the biggest snake in my collection. Good luck with your new snake when you get it. This is probably the best place in the world to find info. I've enjoyed being on here for a number of years now and have learned lots!
