Emperor Tetras + Discus = Trouble
From experience they are not the best fish with Discus, I had to get rid of mine. After watching with the lights on and when they were out I could see them harassing the Discus, they are quite aggressive fish when they want to be.
Try removing them to another tank for a week and see if your Discus settle down.
Keep your tankmates calm for Discus: Corycats, Bristlenose, Rummynose Tetras, Cardinal Tetras, Neon Tetras, Glowlite Tetras have all proven very good for me.
