1. The temperature difference is too large: The whitening of parrot fish may be caused by too large temperature difference, and they are sensitive to environmental fluctuations. If the water temperature in which they live changes greatly, their body color will also be affected.

2, Lack of pigment: Parrot fish may be white due to lack of pigment, and they need a lot of red pigment to keep their body color bright. If the breeder does not often feed them with colorful feed, it will cause them to turn white.

3. Illness: The whitening of parrot fish may also be caused by illness. Common bacterial infections, colds, water mildew, hypoxia, etc. will all turn white.

Whether parrot fish can recover from whitening depends on the reason why they turn white. As long as it is not a serious disease, they can generally recover.

If the parrot fish turns white because of the temperature difference, the breeder only needs to keep their water temperature constant and wait for a few hours, and their body color will return.

If parrot fish turn white because of lack of pigment, the breeder only needs to feed them with color-enhancing feed regularly, and wait for a period of time, and their body color will return.

If the parrot fish turns white because of illness, it is difficult to recover. Because illness will have a great impact on the physique of parrot fish, their body color may also change.
