Is she definitely a Columbian Red Tail boa? I just want to make sure because the same store sold me a corn snake as a certain morph and it wasn't so I just wanted to make sure she is what I purchased her as.

I plan on getting her a cage when she outgrows her tub but looking at her current size and the size of the tub (32qt), how much longer do you think I have before I need to go out and get her a new cage?
