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

4x2x2 is just a big a 40 gal breeder is limit. plus I can't find any enclosures that are less then 300-400 dollars so I just give up my hopes for bearded dragons
If your good at making things or have some one who is check out the DIY board--- there are ideas there you can get -- some people have used old dressers entertainment centers etc...........
