Why Does My Fish Have White Fuzz on It?

If your fish has white fuzz on it, there’s a good chance it’s suffering from a fungal infection. While not always serious, these infections can be quite uncomfortable for your fish and, if left untreated, can lead to more serious health problems. Most fungal infections are caused by one of two types of fungi: Saprolegnia or Achlya.

These fungi thrive in damp, humid environments and can quickly spread from fish to fish. In addition to fuzzy white growths on the skin, you may also notice your fish scratching itself frequently or acting listless and uninterested in food. If you suspect your fish has a fungal infection, the best course of action is to take it to the vet for treatment.

In most cases, the vet will prescribe an anti-fungal medication that you’ll need to add to your fish’s tank water. It’s important that you follow the directions carefully and treat all of the fish in your tank, even if they don’t appear to be affected. This will help prevent the fungus from spreading and infecting other fish.
