I know a lot of people use racks or tubs for their snakes, but I prefer to have them visible. I'm moving my bci (3.5-4ft? *just a guess, never been measured) from a standard 20gal to a 40 long. Looks plenty big enough for him for now. I was going to have a custom enclosure built but it's a long story and it never got done. I bought the 40 because I would've bought it for my bp eventually anyway so this buys me some time to have the 5x2x2 built.
My question is, at what size is he too large for the 40long?
