The reasons why fortune fish turn white:

1. Lack of light. It may be that there is no exposure to light for a long time, causing the red pigment in the body to fade. This is normal. You only need to maintain light exposure to restore body color.

2. Change water frequently. In the process of constant water changes, in order to adapt to the new water, your skin will continue to change and adapt to the water environment, resulting in a lighter body color.

3. Signs of illness. When a fish becomes sick, its color will gradually turn white, and it will appear to be covered with a layer of white flocculation or patches, and even the fish scales will fall off. Timely medication is required for treatment.

4. Being frightened. The whitening of fortune fish is usually caused by being frightened. Usually, when fortune fish arrive in a new environment, because they cannot adapt to the environment, their body color will easily turn white, and some may even turn black.

5. Water temperature changes. Severe fluctuations in water temperature will also cause its body to turn white. Especially when the water temperature drops suddenly, its body will be irritated.
