Many aquarium owners are familiar with the condition known as ‘dropsy’, though they may not understand how this condition affects the health of the fish in their care. Dropsy is a potentially serious health condition that can have a variety of contributing factors, and may or may not be treatable by utilizing proper fish care procedures. The term ‘dropsy’ actually came from an older name for edema in humans, which displays some of the same symptoms as fish dropsy. Being informed about the causes, treatment and prevention of fish dropsy is a very important part of pet care, since it will allow you to easily identify this condition in your pet fish if it occurs. Here is some general information about fish dropsy, which will help you to better understand this condition.

CAUSES

Fish dropsy is usually caused by a bacterial infection, though the direct cause of this bacterial infection can be slightly more difficult to identify. Most bacterial infections in fish are the result of contaminated food or by the growth of bacteria in unclean aquarium conditions. It’s also possible that a fish may develop the symptoms of dropsy after experiencing kidney failure, liver failure or heart failure.
SYMPTOMS

The most noticeable symptom of dropsy in fish is a visibly bloated abdomen. This is caused by excess fluid building up in a fish’s body, which causes the resulting area to become swollen. Most fish afflicted with dropsy develop a ‘pinecone-like’ appearance, as the swelling of their body causes their scales to begin to protrude from their bodies. Loss of appetite, lethargy, sunken eyes and discoloration are all symptoms that may also be associated with dropsy in fish.
TREATMENT

The treatment methods for dropsy in fish usually involve the administration of antibiotics, though this may not be entirely effective. The best way to administer an antibiotic medication to a fish with dropsy is to add the medication directly to a fish’s daily food portion. As long as your fish is still eating, they will consume the medicated food before the antibiotic ingredient dissipates into the water. If you are feeding your fish a live or frozen diet, try to maintain a 1% ratio of the antibiotic ingredient to the amount of food. For live food, it may be necessary to prepare a diluted solution of the antibiotic and water, and then insert this solution directly into live food organisms by using a syringe. Try to only feed afflicted fish the medicated food, as they should already have been kept in a quarantine tank.
PROGNOSIS

In general, many fish afflicted with dropsy end up dying from this condition. The reason for this is that by the time their abdomen has become visibly swollen, internal damage from the excess fluid buildup is usually beyond repair. This is the main reason why it is important to diagnose and treat this condition in your pet fish as soon as possible. If you are able to catch a dropsy infection at an early stage, you will greatly increase the chances that your fish will respond well to treatment.
