Diseases in Goldfish are common, contagious to other goldfish but can

be cured. If you noticed the disease in early stage or better, if you

noticed that something is wrong with your goldfish it will be easier to

treat the disease. Goldfish are strong, durable and hardy species, most

of them will recover. Goldfish diseases diagnosis is an important part

of the overall goldfish care. There is no need to be an expert; you just

need to be aware to your goldfish.

Goldfish fin rot is one of the most common goldfish diseases. This disease caused by several negative

types of bacteria (bacterial disease), in many cases we can see the fin rot disease burst the same time

with other disease, It is not difficult to treat but if you will neglect the treatment it will cost the fish lives

and other will infected. It is also very easy to see the fin rot disease burst especially in her early stages.

The first symptom is when the fish fin edges turn white, afterwards, fins start to fray and the last stage

is mostly when entire fin rot. The smart move will be to prevent it from the beginning. Fin rot occurs

when there is poor water quality, overcrowding in the tank, overfeeding and uneaten food, high levels

of stress can lead to fin rot as well. By maintaining your tank (changing water, replace media) you can

prevent the fin rot disease, but if the disease burst you should know how to treat it. This disease can

be treating by performing water changes, adding salt to the tank and if necessary to use medicine

or antibiotics. Another common goldfish disease is the goldfish ich.

The ich refers to a ciliated protozoan of the genus Ichthyophthirius.Ich is present all the time in aquarium

just waiting the "right" time to burst. Ich burst when a fish suffers extreme stress such as sudden drop in

temperature or when he suffers from fish attacks,  it can also burst when a new fish enterer an establish

tank or when the temperature rising. Water changes are very important fighting ich outbreaks when we

change water it is extremely important to "vacuum" gravel. Another way to treat ich is by using

commercial chemicals. The last treatment is perhaps the best one; quarantine for several weeks

(3-4 weeks) can save the entire tank.

Goldfish anchor worm can be lethal. Anchor worms can be found anywhere on your fish, including the eyes,

gills, and fins. The worms dig with their anchor-shaped heads into the fish muscles, skin, and gills;

sometimes these worms reach to the goldfish internal organs. A fish infected with anchor worm will rub its

body against the gravel or decorations trying to rid of the parasite. Unfortunately, anchor worms are highly

contagious. You can treat them with potassium permanganate as a dip at 100mg per 2.5 gallons (about 10

liters) of water but if you are not familiar with the potassium permanganate you can try a salt dip.
