It’s never good when goldfish begin acting differently and showing signs they might be sick. It is often hard to determine what is causing sick goldfish to act in a particular way. Detecting a goldfish illness can be easier if you are aware of possible symptoms associated with the most common diseases and infections.

Although some symptoms may be signs of different problems, understanding what to look for can be helpful in catching and treating an illness before it’s too late.

Parasitic Goldfish Illness

Diseases associated with parasites are usually caused from bad water conditions or stress. The most common parasitic disease is goldfish ich. This goldfish illness can be deadly if it is not treated. The goldfish will seem extremely irritated. They’ll usually rub against the side of the fish tank.

Their eyes may become cloudy and they may have difficulty breathing. Physically the goldfish will have white spots all over. Some people say it looks like the goldfish has been sprinkled with salt. The entire tank will need to be treated to kill the parasite. Adding aquarium salt to the water may also kill the parasite.

Bacterial Infections

Bacterial infections cover a variety of common goldfish illnesses. Tail and fin rot and ulcers are caused by bacterial infections. Symptoms of bacterial infections are:

  • ragged fins
  • white or open red sores
  • bulging eyes
  • reddish tint to the skin

Open sores can be washed with peroxide and an antibiotic ointment should then be applied. Adding a small amount of aquarium salt to the tank will help make up for the amount lost by the infection.
