Hello. I'm brand new to boas and i have some questions. I held a boa the other week and was immediately hooked. Now i want one but don't know the difference between bcc and bci. I love the red tail and I think I heard that one of the 2 species holds the red better than the other. Is this correct? Also is a aquarium that has a 48" x 18" floor space big enough for a boa? Should I get a baby, or adopt off kijiji or something? I love handling snakes and I am worried that if i get a "used" one that it may be unpredictable. Like I said, I'm new to boas so any help would be appreciated. Thanks!
