Dropsy—and its underlying causes—are not contagious. However, the conditions a goldfish needs to recover from dropsy are different than the normal ideal conditions of an aquarium. A second tank of similar size can serve as the goldfish’s sickbay. Perfect conditions must be maintained for the goldfish’s immune system to have the best chance to recover. The water should start out at the same temperature as the water in the goldfish’s original tank. This will prevent the goldfish from going into shock in its new environment. The ideal water temperature for a goldfish with dropsy is 80 degrees Fahrenheit. A relatively high water temperature will prevent bacteria from multiplying.  Raise the temperature in the tank by a two degrees every hour until it reaches 80 degrees Fahrenheit. Use an adjustable aquarium heater so you control the rate of temperature increase. The kidney’s function is to keep the fish’s internal salt levels balanced with the salt levels in the water. When the kidneys shut down, salt builds up in the goldfish. Increasing the salinity of the tank helps the goldfish to stay in equilibrium with its environment—which will boost the goldfish’s immune system.  Add one teaspoon of salt per gallon of water. Don’t add too much salt. A high level of salinity will put even more stress on the goldfish’s kidneys. The goal is to keep the goldfish in perfect, clean conditions while it recovers from dropsy. Changing the water on a regular basis will help achieve this goal.  Aim to change the water once every three days. Remember to slowly increase the temperature and add salt to the new water.
