Diagnosing goldfish disease as early as possible is an important part of maintaining your aquarium. If you can’t readily identify a goldfish disease see your local vet, or pet store.

Fish live by absorbing oxygen and they give off carbon dioxide as a waste product. Plants in daylight do the opposite, so that what is poison to one species gives life to the other. So adding plants to your aquarium will assist in keeping your goldfish healthy and disease free.

Preventing disease is always easier than curing it, so by keeping your aquarium clean, feeding your fish properly, avoiding wide temperature fluctuations and performing partial water changes as necessary you will go a long way to keeping your fish healthy. However, no matter how well you maintain your tank, from time to time one or more of your goldfish may become stressed or ill.

Some common goldfish diseases are discussed in this article.

Anchor worms will appear as a 1/4 to 3/8 inch piece of string with a forked tail. Large anchor worms can easily be seen. They appear as clear, brownish-red, or greenish-white strings. Once the anchor worms have buried themselves into the flesh of the fish open sores may appear on the skin. Anchor worms may be visible in the sores. Frequently this parasite is introduced into the fish tank from adding live food to the tank, or from aquarium plants, especially those taken from rivers or creeks. Anchor worms attach beneath the fish’s scales and bury their anchor-shaped head under the skin causing ulceration and distress to the fish.

Anchor worms are highly contagious and must be treated immediately. Your pet store will have a treatment for anchor worm, usually in the form of a gyrase inhibitor that can be added to the water in the tank. This should be effective in killing the parasites within three to four days.

Swimbladder disease should be suspected when a fish has difficulty stabilizing itself in the tank. It is not uncommon in goldfish although fancy varieties appear more susceptible to this disease. It can be genetic in origin or caused by a variety of other factors including inadequate or improper diet, bacterial infection or even poor quality aquarium water.

Apart from improving the water condition if that is necessary, some fish keepers suggest feeding your goldfish thawed frozen peas. Feeding the fish with sinking food instead of floating food can minimize the intake of air. It may also be worthwhile moving your sick goldfish to a shallow tank while you treat it. This may lessen the stress on the fish. Swimbladder disease can often occur quite suddenly in previously healthy fish.

Dropsy is not a specific goldfish disease, but appears as a condition where the fish’s abdomen becomes swollen due to a concentration of fluids in the body tissues or cavities. The abdominal swelling often creates a pinecone effect causing the scales to protrude from the bod. The cause of the swelling could be any of several conditions including cancer, internal parasites or bacterial infection, cancer, internal parasites. Depending on what has caused the condition dropsy may be contagious. There are no known successful treatments for dropsy and the condition usually proves fatal.

If the fish has not been fighting, torn or frayed fins are usually indications of tail or fin rot. This is a bacterial infection that first presents as a whitish edge on the fins, before the fins begin to rot away. It is easily treated with antibiotics available from your local pet store. Ensure the medication states that it treats fin or tail rot. In some cases a secondary fungal infection can occur. In this case, treat the fin rot before dealing with the fungal problem.

Fungus is usually a secondary infection. A fish with an open wound or sore caused from injury or disease may suffer from a lack of mucous around the area of the wound. Open wounds like this can often attract a secondary fungal infection. Look for patches of white or grey fuzzy puffs attached to the skin. There are several different treatments available for fungal infections from the pet store. Fungus responds well to quick treatment.

Perhaps the most common parasitic disease in goldfish is ick. It is frequently present in freshwater fish tanks and will infect fish in poor general health or those that have suffered recent infection. Ick is characterized by small white dots that look like salt sprinkled on the body. The fish may attempt to scratch the infected areas on the wall of the tank which can cause further damage. Rapid breathing and cloudy eyes can also be signs of ick. See you pet store for ick treatment. Badly infected fish should be moved to a hospital or quarantine tank for treatment but it is important to also treat the main aquarium, ensuring that the parasite has been removed.

Goldfish are quite hardy fish but there are still many diseases that they can suffer from. If you want your goldfish to live a long and healthy life you must ensure that you manage the aquarium properly and treat sick goldfish immediately that any symptoms appear.
