I am moving in april and have been thinking about upgrading the size of Monty's tank since she is a growing girl.

I currently have her in a 3' long by 1' wide by 1.5' tall. Would a larger space stress her out?

If I do decide to give her a larger tank, should I put her in the new tank when I get there (my new house) or wait a little while to not stress her out too much at one time?
