What is the best size cage for 2 adult beardies? i have them in a 40gal. breeder but there getting to big for it. I will have to divide them when they are full grown. At first i was thinking of getting a 72x24x18 and divide it. I also just thought about keeping one of them in the 40gal and get a 4ft cage for the other one. A few places said that you can have 2 adults in a 48x24"cage but that seems to small. What is my best option so they have a good amount of space? I would like to buy (or build) a 8ft cage and divide it so they have more space but i don't think i would have enough room and its a lot of money.
