Hello

I have a ball python just short of two feet, and it is in a (I think) 5-gallon tank. It has the same length and width as a 10 gallon tank, but a different height. I want to change the tank it is in. I have access to a 40L tank and stand, but I wasn't sure if it was acceptable for the snake to go from a somewhat smaller enclosure to a larger one. Can I change its place or should I invest in a 20L tank?
