However, if you notice that more than one of your fish is exhibiting symptoms of dropsy, then there is something wrong with your tank or a common element that is causing stress in all of your fish. Unlike other fish diseases, dropsy is generally easy to spot. Before dropsy causes a visible swelling in your fish, it may cause your fish to appear lethargic, and they may eventually lose their appetite and stop eating for a few days before their belly starts to swell.
As the disease progresses, your fish may develop skin lesions, or fin rot, and their internal organs such as the kidney or liver may be damaged.
Your fish may also show signs of discoloration, a swollen anus, pale gills, or a curved spine. Symptoms progress aggressively, so if you notice one, act right away. Unfortunately, some fish may show no outward systems at all, making this disease difficult to detect before it becomes fatal. Since stress is the main factor that causes dropsy, the best way to prevent the condition from appearing in your fish is by minimizing factors that may increase their stress levels.

Fish with dropsy may also have trouble swimming, either from damage to the swim bladder, pressure on the swim bladder from fluid in the abdomen or changes in the fish's buoyancy due to the built-up fluid.
Since dropsy is a symptom, not a disease, other symptoms will often present themselves at the same time. Unfortunately, in most cases dropsy is the last sign of irreversible damage. However, you can sometimes save the fish.
