MY first advice is not to get two, they need to be housed seperately. They are very solitary and do not like other beardies. Granted it can work out, its mostly with experianced owners. Alot of dominace and eating issues can occur.

Secondly, Ceremic tile! It makes cleaning a breeze and you never have to replace it. Crickets and roaches love to hide under reptile carpet making it a pain to have.

Crossfire dragons DIY is a really good cage ( The guy who made it is also awesome, old friend of mine ) Just remember tallness is not an issue because they are floor space needing creatures who get to fat to climb well

One MVB bulb will be fine, what kind are you looking into buying?

Just remember to keep the cage very simple, a beardie can get lost in such a big cage. Keep us updated on them!
