Hehehe. That game series is probably my 1st-3rd favorite game series ever.
Are you planning on housing them separately? cause if you aren't, I highly suggest that you do not put them together in the same tank, especially if even one of them is male.
Bearded dragons are territorial animals and tend to dominate other beardies when kept together. This can lead to stress and a lack of eating, as well as missing limbs and other serious injuries if they attack each other.
There have been cases of dragons having to get all of their limbs amputated because of tank mates. The beardie actually survived without any limbs for a long time, but that's cause he was rescued and cared for well.
Even if they seem like they get along well, you will often times miss the signs of domination till its too late.
