Uromastyx & Bearded Dragon Lizards

Question
Can they live together in the same cage?

Answer
 Not at all.  Beardies live in a semi arid climatem while uros are true desert lizards.  Very different temperature and humidity requirements.  A beardie's basking spot is about 20 degrees cooler than a uro's.
 Besides this, their food requirements are different, and lizards are highly territorial.  Adult lizards will fight for territory.  The rule of thumb here is that each lizard should have his/her own habitat.
