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. Water conditioning is the process of removing these chemicals from the water. This part is essential in order for you to properly care for your discus fish. Discus Fish originated in the waters of Brazil, which is soft and acidic. So, you have to replicate the water quality in Brazil in your fish tank if you are going to keep a Discus Fish or any other fish found in Brazil. You also have to keep in mind that larger volumes of water is easier to keep stable than smaller volumes. Just make sure that the discus fish are the largest fish in the tank. When it comes to their food, discus fish can be fed with aquarium foods. You can feed the discus fish with frozen bloodworms and brine shrimp. Adult discus fish can be fed once a day but juvenile ones should be fed at least 3 times a day. And, you have to keep in mind that Discus Fish are rather sensitive when it comes to water quality. Water quality is very important if you plan on keeping a Discus Fish. Try to keep the water clean and also its chemistry stable. You have to at least change 50 percent of the water once a week and you have to make sure that the PH level is also stable. First off, you need to know that the discus fish has a shy character. You should equip your aquarium with different corals or coral like ornaments which the discus fish can hide in or at least have some privacy. If these are not available, you can buy some potted plants. These are also good places where the fish can spawn. To be honest, it s much more bothersome to be treating illness rather than just plainly keeping a routine of maintaining a clean tank, at least you can put it in your schedule. Besides, keeping your tank water clean is just one of the responsibilities of owning an aquarium. Imagine, what would life be if we don t have air to breathe?
