what is the "normal" growth rate of a columbian bi. i know most of it depends on feeding (which i will need some advice on) like what % of the animal weight do i use to find the appropriate size food. but anyways the reason i am curious about the growth rate is i want to eventually when it is bigger, i want to get it a enclosure that is to my liking most likely 6'x2'x2' i want something big so he has all the room he will ever want or need something it can roam around in and climb in i know that much room is probably not needed but i feel that the more room the better... thank you
