Getting a bigger batch spreads this aggression from the alpha among more discus and they are left alone and not bullied that much.
So its more a thing about the dynamics of your discus batch .
Removing your background is not a wise thing to do in their initial adjusting stage IMO , especially if you have movement and lights in the back of your tank . You will take out their only secure hiding spot .
After they are comfortable and adjusted 1-2 months from now , you can keep them with all 4 sides of the tank open if you like .
For now, I think their skittish and darting behaviour is mainly because they are still new to your environment , so I think they will be all right in a couple of weeks .
