George, you have a proven pair. Critical and hard to accomplish step one complete. From here on be prepared to try and try again. Your discus parents have to learn this just as you do so let them learn. I have a friend who has bred both discus and angelfish for more than 30 years. He does not, other than water change, put much effort into the breeding of the fish. If they spawn and the fish eat eggs or fry his belief is that his fish had a nutritious meal and they all move on. I have had spawns where the male has defended the spawn from the female. I removed the female and allowed the male to raise the fry. You can put the pair back together at a later time. They seem to remember each other after a separation so don't concern about it.
