We just rescued a Frilled Dragon from a pet store, we've read up as much as we can, but I'm still trying to figure out the best cage for him. Right now he's in a regular 40 gal tank with a lot of branches and a dish of water. Would a screen cage work? How do you keep a gradiant temp with a tall cage? He's a tiny guy still (3 3/4" snot to vent).

Any tips or advice would be great! Thank you
