Abstract
Any factor that upsets the hemostatic balance of the existing body creates a condition called disease. Each group of pathogens has specific symptoms in fish, in other words, in general, the behavior and appearance of sick fish is different from healthy fish. Dropsy is one of the most ugly and difficult diseases of aquarium fish. Almost all types of aquarium fish can be infected with this disease, which unfortunately leads to the death of fish in 99% of cases. This disease is one of the easiest diseases to diagnose. But it can be said that it gives almost no response to treatment.
