Make sure though to never overfeed your fish. The extra food will just become dirt inside the tank. For younger discus fish, you should feed them about four times daily, older fish only needs to be fed twice a day. Growing fishes need the food more. Discus fish should also be fed live or frozen food from time to time. Do give your discus fish an area in the tank for them to spawn. Discus fish lay their eggs in a flat vertical surface area at the bottom of the tank. Some use certain plants while some say that an overturned pot will do. Do vary the diet of your discus fish. When your fish are breeding, a varied diet is important to boost their reproductive system upping their chances of spawning. Before, because of its limited supply, only a selected few would be able to get their hands on a discus fish, let alone a handful of them, luckily today, many are now able to get their hands on them, and if you re one of those lucky persons, then you should know how to provide them a good environment so that they can leave healthy and stress free. The acidity of the water should also be kept at a constant level. The water pH for discus fish to thrive in should be between 5.5 and 7. Any more acidic or alkaline than these numbers is a sure way to kill your discus fish. Lastly, the water hardness should also be considered. Although discus fish are not that sensitive to water hardness, it will play an important role in keeping them healthy. You have to remember that discus fish are schooling fish that likes to be kept in small groups of five to eight. They need security of a school around them and getting them in groups will help in reducing their stress levels and also help in keeping them happy. Another advantage of keeping them in groups is that you are actually increasing their chances of mating and breeding and produce more discus fish, which you can keep or even sell for profit. This is why it is important that you monitor the water s chemistry every time you change the water in your discus fish aquarium. In most parts of the country, chlorine and chloramines are added to water supplies. And, as you can imagine, chlorine is a chemical that is not good for discus fish. Today, there are available test kits that you can use to test the water if these chemicals are present in the water and also how much of it is present in the water.
