It is common knowlege that rtbs like to climb as youngsters, but i was wondering do they still climb when they are larger 4-5 ft or even full grown. (in other words if they had a large enough enclosure would they still climb as adults?) this is going to determine how large of an enclosure i am going to build.

For an adult, it would be better to have more length than height.

thats what i was thinking that how i alwasys see adults at the reptile shops i visit. thanks.
