Reasons Why Your Fish is Turning White

If your fish is turning white, then there is a very high chance that it is ill. While there is no need to panic, you need to identify the reason behind this.

First of all, your fish may be having any of the following problems:

  • Fungal Infection: If your fish has some white fuzz on it. it’s called an “itch“. It is a very common disease in fish, but it is also treatable and preventable.
    What happens is that small white fuzz starts appearing on your pet fish’s fin. Freshwater fish are more prone to this disease.
  • Stress: You bring home your pet fish and place them in a very small bowl. If that fish is from freshwater, then it is usually accustomed to very large spaces. Placing it in a small bowl will stress it out, which in turn will affect its health.
  • Diet: It is important to know that feeding your fish can have adverse effects on its health, which can force them to change color. Make sure to research what species of fish you have and what are its dietary requirements. Whether it eats small plants or large chunks, a healthy diet is an answer.
  • Sunlight: Just like all human beings need sunlight to stay productive, so does fish. Placing your fish at a corner that has no sunlight may be the reason why your fish is changing colors. In fact, according to a study, the itch is usually caused by a closed-off environment.
