Couple questions....
How big is your tank?
How many fish are in it?
How big are the discus?
What kind of setup: Plants, substrate etc....?
How did you cycle the tank, and for how long before adding the discus?
What are your water parameters and what were they when you put the fish in?
What is the temp of the water?
Discus can be sensitive fish, so we need to know the answers before advising you.
