You should have three tanks or aquariums in your home. You should have them bubbling for almost four weeks before putting in Jack Dempseys. Put the male in one tank and female in the second tank.
Then you should maintain the temperature of the tanks between 76 to 82 degrees Fahrenheit which is quite suitable for breeding Jack Dempseys.
Make sure you have a couple of Jack Dempseys and their size should be close to each other. It will help in breeding and you will get maximum result.
You should provide protein rich food for the couple which will prepare their bodies for the stress of spawning. The cichlid pellets, night crawler and a pinch of hamburger serve best in this regard.
Then put a flowerpot or slate in the tank that you want to use for breeding. A foam should also be over filter opening of the aquarium which will save the tiny fish, also called fry, from getting pulled into the filter.
Now, you should put both, male and female, in the similar tank. If they start fighting with each other, they will not have mating. However, if they show calm behaviour then the breeding process will become smooth.
Jack Dempseys do not eat their eggs, so leaving the couple alone will not cause any damage. Their eggs will take two to three days in hatching.
In starting days of fry, try to feed them with freshwater fish flakes, micro worms and cichlid. When you observe that these babies become 1/2 inch long, immediately remove them into another tank.
