Cages?

[Relayer]

I've been looking around the web at the different cages available. I have a bci about 2 months old and around 22". Right now its in a 20 gallon aquariuam. Should I step up to a larger aquariuam before the cage?
Also there are many cages out there available, ex. boaphile plastics. What is everyones opinion on these and which do you reccomend. I'm thinking about designing my own as well. I guess I'm looking for suggestion on sizing, proper ventalating, heating, and humidity.

You could go strait for the larger cage for her if you want to just remember to put several place's for it to hide in there! As for type I like to look's of the Boaphile Cage's and for price it's probably one of the best deal's!
