im *thinking* about getting two 40gal breeder tanks so they each have their own.. ive heard the 55gal just isnt deep enough for them. The only problem I have with that is I then have to get two stands because we risk the basking lights burning our kids if they are on the bottom of say a 40gal breeder rack where you can stack two of them.. they love watching the dragons but we worry about them burning their hands on the lamps by not paying attention.. having two matching 40gal breeder tanks will look nice i think.
