behaviors return to normal after adjusting to change?

So I just recently rescued a Beardie from someone. Wasn't great care he was being provided, but from what I've seen it would have been worse. Took me like two hours to do a complete clean and remodel of his tank. Anyways back onto topic, since I put the new Beardie into my reptile room, my first Beardie I had in there has been going berserk. I know the beard turning black and fluffing and head bobbing is just him making it known of his territory. But since they are in seperate cages, will come out at different times, do I need to move the new one out of his site or something? Or will he just get used to the other Beardie being there and calm down you think? Never had this problem so Im only assuming things.

After some further research, I have moved the tanks so they cannot see each other. Although they still get some black in their beard and run in the tank when they hear one another. I guess I'll just end up moving one to a different room if they dont calm down haha.
