Congrats on your decsion to get a beardie! There great lil lizards.
You may started one of those huge debates. "Should I keep them in the same enclosure and how will they get along?" lol I think you just might find a little bit of everything once people start repling!
IMO I would say no, house them seperately. That way you dont have the worry of how they will respond to each other. You wont have to wirry about them fighting over food where one will be more dominant when feeding and actually cut the other one off, then you have the problem where you see one growing and the other basically starving. Theres always the fights that can occur for whatever reason and then you run into injuries, vet bills etc.
If I remember correctly beardies in the wild are for the most part solitary animals only getting together as adults to mate. If I am right on this then that should give anyone the best answer on wether or not they should be housed together.
