1. Reason: Red parrot fish may turn white because there is too little oxygen in the water, and their demand for oxygen is high. If the dissolved oxygen in water decreases, their body color will turn white.
2. Solution: The breeder needs to give them oxygen immediately to ensure that the dissolved oxygen in the water is sufficient. Changing the water frequently at ordinary times can also ensure sufficient dissolved oxygen in the water.
Second, the water quality is too poor.
1, reason: The whitening of red parrot fish may also be caused by poor water quality, because poor water quality will also affect their pigment synthesis, leading to their body color whitening.
2. Solution: Breeders need to change water immediately to ensure clean water quality. It is best to change the water every 2-3 days, and the amount of water changed each time is controlled at one third of the total water. If conditions permit, filters can be installed to slow down the deterioration of water quality.
Third, the water temperature is low.
1. Reason: The bleaching of red parrot fish may also be caused by low water temperature. If they live in a low temperature environment for a long time, their body color will also turn white.
2. Solution: The breeder needs to raise the water temperature to 25-30℃. If possible, it is best to install a heating rod to keep the water temperature constant.
Fourth, fear
1. Cause: White parrot fish may also be caused by fright. They are timid. If they are frightened, their body color will become lighter.
2. Solution: Breeders need to keep the surrounding environment quiet and wait for them to recover on their own.
