There is a common misconception that discus fish are more prone to disease than other tropical fish. This is simply not true, they are not more prone to disease than other fish. The problem with discus fish is that they do not adapt well to various environmental and water conditions, while other fish are. This weak adaptability makes them more prone to stress, and a more stressful fish is more prone to get a disease.
Discus research has shown that a fish that is under minimal or very short periods of stress are fine and will not be more prone to disease. These shot periods of stress can include: being transported, water changes, and fighting. The issue with disease comes with longer periods of stress, such as poor water quality.
A discus fish that is not stressed can normally fight off any of the common diseases known to the breed. Like all fish, most discus live with the pathogens that cause many of these disease without getting sick. But once the discus is under long periods of stress, these pathogens can take over the discus's immune system.
