I have two young beardies that have been housed together for awhile. I don't think they would know what to if they were separated, they are the best of friends. I turned off the lights for bed time, and Livia went in her corner and fell asleep, Draven was in the hammock already asleep... Shortly later he moved up to Livia... Laying side by side together sleeping. It was the sweetest thing I have ever seen.
