I have 2 beardies, both are about 3 months old. I have each of them in separate enclosures, but they can still see each other from where they are. Should I not have them set up this way? They wave a lot and one runs along the glass. I just don't want to cause them any stress. Thanks!
I'd keep an eye on them and see how they react over time. If they appear stressed out then it's best to stack the tanks or block the view in some way so they calm down. In some cases they may be stressed, in others they may not react much or not get too worked up anyway. I'd observe and just consider options based on this particular setup.
