what is dropsy in fish

Dropsy is a condition in fish caused by the buildup of fluid inside the body cavity or tissues, and it is a symptom rather than a disease in its own right. It can indicate a number of underlying diseases, including bacterial infections, parasitic infections, or liver dysfunction. The bacterial agent that causes Dropsy is one of several gram-negative bacteria commonly present in aquarium habitats, and the underlying cause of fish becoming infected in the first place is a compromised immune system that leaves the fish susceptible to infection. Poor water quality, viral infections, sudden changes in water conditions, and a prolonged period of stress that may compromise the fish’s immune system may all trigger the symptoms of dropsy. The following symptoms may be observed: swelling of the abdomen, eyes that are beginning to swell and bulge, and scales that are sticking out. Dropsy is not easily cured, and treatment is geared toward correcting the underlying problem and providing supportive care to the sick fish. Prevention is the best cure, and almost all the factors that stress fish enough to cause them to be susceptible to infection can be prevented.
