The bacterial agent that causes Dropsy is one of several gram-negative bacteria generally present in aquarium fish keeping. The underlying cause of fish getting infected in the first place is a compromised immune system that leaves the fish susceptible to infection. This can be as the result of stress from a number of factors, similar as the following:


• Poor water quality
• Ammonia or nitrite spikes
• Large drop in water temperature
• Stress from transportation
• Lack of nutrition or balance diet
• Aggressive tankmates

It's important to move the infected fish to another tank to separate them from the healthy fish. Meanwhile, perform a water change on the original tank and cover the fish nearly for the appearance of symptoms. Salt should be added to the Hospital tank at the rate of one tablespoon per gallon of water. Keep the tank clean, and perform weekly 10% to 30% partial water changes. Give a variety of fresh, live, premium quality fish food. Frequently this will cure the infection in cases that aren't advanced. Keep the fish under observation for several weeks after symptoms vanish.
