My 8 month old BRB is currently in a 1ft square terrarium and is around 27" long. How long will he be able to stay in this viv and will it be ok to move him straight into a 4ft one as I'm not keen to buy a 2ft and then move upto a 4ft...seems a bit unneccesary...but I'm very inexperienced (thisa is my first BRB and only my second snake) so may be completely wrong about this!
He should be alright for a bit, but I don't think jumping straight to a 4 ft would be a good idea...... but you could also get a 4ft and then section it off some how so it's smaller for a while she grows.
