I believe that is a 30 gallon which is not big enough -- they will need a 4x2x2 or atleast that is what is recommended-- I purchased a Zen Habitat which is a 120 gallon from ZenHabitats.com - you can always build one if you are creative or handy of which I am not - check out the DIY board for ideas or you can always google reptile habitats and see what you find there
