Black/other darker colored dragons and roommates

[DrScales]

So I've been thinking of getting another dragon. The one I've been looking at is mostly black/grayish and I would like to know how to tell if he's sick or something, as I've read that most beardies will darken their beards for territorial reasons, courting, or just because they're sick. How would you be able to tell? Also, my beardie is kindof between that juvenile and adult stage. Would it be okay to keep small dragons in a terrarium/vivarium/whatever with him?
Thanks, Josh.

Hi. Don't put another beardie with yours. He'll think its food. Can you post a picture of the beardie your looking at?
