I used to keep discus as well.
A pair formed out of the 14 fish and spawned twice.
But unfortunately the eggs never hatch.
Did not spawn? Ermmmm, probably both of the discus is female. happen to me before. haha.. If you notice there is spawning, might be you could try to use metalyne blue. It will protect the eggs being infected with fungus also dont forget to use wire mesh to protect the eggs from being eaten by their parents too.

It is not easy to spot the difference between male and female of discus as their color and patterns ranging from blue, blue-greenish, orange to red.
When I was 15, I have managed to successfully bred them from young fry to adulthood.
What I normally do is that I use 2.5 feet tank, and did some fish pairing, based on trial and error using aquarium partitions supported with suction disc.
The males are often more brightly colored compared to females. You need to spot them closely.
If you get a successful pairing, the fish will lay eggs on hard, cylinder shaped surface, which is placed vertically. A 3 inch to 3.5 inch size PVC pipe placed vertically is good enough. Use white colored PVC pipe so it is easy to spot the egg cluster.
The egg clusters are bright orange colored. Avoid provoking or agitating the fish. If threatened the pair of fish will ate all the eggs.
When the eggs hatches, the fry will feed on the mucus on the parents scales, and both parent take turns in feeding and nurturing the young. The young will swim side by side with the parents to feed. At this point, you might want to switch off the water filter, to prevent some young fry to sucked in. The water must be well air-circulated with tiny air bubbles to maintain constant oxygen level. Some will also die naturally in the growing up process. Again avoid provoking or agitating the fish, the parent will eat the young if it felt life threatened. You can feed the fry with daphnia, a micro-organism, the parent may go on hunger to concentrate on nurturing.
It takes 4 to 5 weeks for the fry will take its adult form, which is the size of 20sen coins. When they reaches the size of 50sen coin the young can be separated from the parent and will grow up healthily.
Totally agree with blitzboy. Normally after pairing, not only you need trial and error, the discus parents also need trial and error. Normally, it will only sucessful after few times of spawning.
To prevent the parents from eating the eggs, use wire mesh until it is free swimming. Besides that, I would recommend bottom free tank for the discus's babies.It is easier to maintain and clean.
As what blitzboy said, you will need a good oxygen level to have a happy discus because discus loves warmer water (27 - 30 Degree Celcius). When the temperature in the water is that high, it will not only kill most of the bacteria but also will kill your discus. Warmer water will have lesser oxygen in it.

can i.. mix them with guppies?
I dont know if we could keep it with guppies. Ermmmm, normally we keep discus with angel fish or neon tetras.

One good advice from my breeder friend who experience the field for close to 25 years now, arowana good money but sometimes doesnt sell well, discus on the other hand always got stable demand.
Yarh. There is always a demand for discus. On the other hand, discus spawn quite frequently. Approximately about few times a month. Get about 6 (2.5") young discus. Slowly grow it and most likely you will have about 1 or 2 pair of discus when they are adult.
