Getting Discus Pairs to Spawn Again
Discus are considered to be the “King” of all tropical fish. Breeding discus can be very challenging, even for the most advanced tropical fish hobbyist. It requires lots of patience to be successful. Here are a few tips we’ve learned that might help you get your discus pairs to spawn again if they’ve stopped breeding for you.
Peform more frequent water changes in your aquarium
Discus need clean water to thrive. You might want to up the frequency of your water changes to see if that encourages them to spawn. If you’re changing 25% water once a week, try doing 25% water changes every other day for a few weeks.
Changing water temperature
If your aquarium water is set at 82 degrees, you might want to slowly raise the temperature to 86 degrees for a few days to a week. Then lower the temperature back to 82 degrees during a water change.
pH Change
Lowering your water’s pH can help trigger your discus to spawn. Discus are acidic water fish and are happiest in acidic water. We keep our discus pairs in a pH range of 5.0 to 5.8. Be very careful when lowering the pH of your tank. Try not to lower it more than .3 a day. If you lower the pH in the tank too quickly, your fish might die of pH shock.
