togetherness

Question
Hi Diane.  I was wondering if in a large tank you could put a bearded dragon and a fat tailed gecko together?

Answer
Hi Lisa,
Sorry to say that those species cannot be housed together. They have much different care needs. The bearded dragon requires much higher temperatures and high uvb where the gecko needs much lower temperatures and only a small amount of uvb.  The bearded is diurnal(active during the day) and the gecko is nocturnal (active during the night).  Also, chances are very high that the beardie would make a meal of the gecko at some point.
No different species should ever be housed together.
