This is why treating the wound while it s still small is highly recommended. For this kind of disease, you may want to treat the disease by increasing the water temperature from 30 degrees Celsius to 36 degrees Celsius. Keep the water temperature raised for around 8 to 10 days. By increasing the water temperature, you also need to increase water aeration to keep the oxygen level up. Even if you don t have a big backyard for your dog to play and exercise in, a good corner with about a meter or two of space is enough for you to have a relaxing aquarium to look at. You don t have to train them, and side from the occasional cleaning, they can be kept wherever they are already placed. Of course, like with other pets, you want your Discus Fish to be healthy and free from disease. So, here are some simple tips that will help you keep your Discus Fish alive and healthy for a very long time. For starters, you have to make sure that you keep at least six Discus Fish together. You have to remember that Discus Fish are shoaling fish, which means that you have to put them in groups. 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. These will not only make the tank look a lot better but these things will serve as a hiding place for discus fish and it will also help keep them comfortable. Discus fish are easily frightened and if they have nowhere to hide, they will get stressed easily and can possibly hurt themselves from dashing around the tank and hitting the glass. However, the problem with discus fish is that they are very hard to maintain. You need to have the proper aquarium setup in order for you to successfully raise them and even breed them. You have to remember that discus fish are very sensitive animals that need to be watched constantly. Basically, they will need extremely clear water and you also have to maintain the temperature as well as the pH level of the water at a constant level.
