I recently fell in love with a BCC and have been doing some research. I came across a book that said that a BCC could be housed in a 4ft/3ft/3ft cage. Is that true??? I know that they are not exactly all that active but isn't that REALLY small for something that can reach 12ft? I thought that was a little strange so I wanted to get a few other opinions. How are their dispositions when they age? Are they a bit unmanageable due to their size/weight? Again, I want to get as many opinions as possible before I buy a snake that will get longer than I am! 
(oh yeah, one more thing, I was told that they darken in coloration as they age, is this true?)
