Divided tank set up

What age (or size) BP can you do that with before having them each in their own cage?

What age can you do what with? Im talking about buying the AP T8 or T10 with the Divider so each snake has their own side. They are 4'L x 2' deep x 15" H and then you can use the Divider or not if you only have 1 snake.

I'm sorry, I wasn't clear. If you had the divider in and had 2 BPs, one on each side, how long can you do that for? In essence, you would have 2 cages that were 2' long.

For a BP thats all you need.. I myself use 4' for each because I enjoy watching them climb and stretch out ect... Some people act like a Shoe Box is good enough but in 29 years all my snakes have enjoyed a full 4' as long as they have good hides and fake branches & vines to climb on. For young BP's though that T10/T8 enclosure divided would be good for a couple years as there young anyway.
