So you have a mature pair of discus that have shown an interest in each other but are not laying eggs.
The most important factor in discus farming is the quality of the water, make sure it is soft, acidic and clean. If you have this water, you are most likely stressing about why there aren’t hundreds of eggs in the tank. If you have discus ready to lay eggs, there are a few ways you can help them.
The first way you can tempt them to lay is to feed them a diet rich in frozen bloodworms for about a week. Feed him every day, as well as his other food. This should condition the female and prepare her to breed. Other foods that are good for discus farming are white worm, adult brine shrimp, and chopped crab sticks or prawns. Be sure to buy frozen foods as there is less chance of illness.
Another way to encourage your discus to play is by doing a 25% water change but lowering the temperature of the incoming water by a couple of degrees. This mimics their natural habitat and can trigger spawning. This is a little trick I use on all my young pairs when trying to get them to breed. Make sure all the pH and hardness are the same, making only the temperature different.
The third trick to getting your records to play is to separate them for a couple of days before reinserting them. To do this you can add a tank divider or move the male to another tank. Make sure the female eats plenty when the male is away. When reintroducing the disc, keep a close eye on it for the next 24 hours as the males know they are aggressive towards the female. They should begin courtship in the next few days and hopefully lay eggs afterwards.
