Tips for Increasing Discus Spawn Yields
If you are not getting many discus fry from your discus breeding pair spawns, then try some of these tips below to hopefully help maximize your discus spawn yields.
Lower Water Hardness in Breeder Tank- This is probably the first tip to try if your discus spawns are having terrible hatch rates. Having hard water in your discus breeding aquarium will cause the shell of the newly laid discus eggs to harden quickly. This makes it very difficult for the male discus to fertilize these eggs. Try lowering your water hardness to around 100 to 200 microsiemens. The softer water should give the male plenty of time to fertilize the spawn.
Keep Breeder Tank Super Clean – It’s important to keep your breeder aquarium very clean. Wipe down all the sides and surfaces when doing a water change. Try to do at least two 25% water changes during the week. Clean water will reduce the chances of bad bacteria or fungus killing your discus spawn. Keep your filters clean as well.
Use a Diatom Filter – A diatom filter will help super clean your breeder tank. Diatomaceous earth filters can filter the water down to 1 micron. They’ll even remove parasites, like gill flukes, that are a common killer of small discus fry. The best time to use the diatom filter is right after you’ve cleaned the breeder tank and did a water change. You only need to run the diatomaceous earth filter for a few hours.
