My mom found (possibly) a 15 gallon at a goodwill for 5 dollars. I don't really care if it's beat up, we got another one from a thrift store that is beaten up and doesn't always properly lock, but even then it closes tight enough to keep a super mutant ninja snake, like Mama, from getting out. If we get it before someone else does (have to wait until the 6th), the babies can stay in it and I can put Pumpkin with them. Mama doesn't seem to like having Pumpkin around, but with her getting out of the other tank, I cant keep her in there. It's just a matter of time.
