How do you recognize a fungal infection in fish?

Fungal infections in fish can be caused by different types of fungi, such as Saprolegnia and Achyla. In most cases, only the fish that have a weakened immune system become ill, for example, because they have fought or have (had) another fish disease. Depending on the type of fungus with which the fish are infected, the following symptoms may be observed:

  • A cotton wool-like attack on the mouth, body or fins. This attack, as it were, falls apart as soon as you take a fish out of the water.
  • Lack of appetite
  • Little movement and listlessness
  • The fish often stay in a dark corner of the aquarium
