1. Lack of oxygen 1. Reason: The whitening of red parrot fish may be caused by too little oxygen in water, and they have a high demand for oxygen. If the dissolved oxygen in water decreases, their body color will turn white.
2. Solution: Breeders need to oxygenate them immediately to ensure sufficient dissolved oxygen in water. Change water frequently at ordinary times, which can also ensure sufficient dissolved oxygen in water.
2. The water quality is too poor1. 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, resulting in the whitening of their body color.
2. Solution: Breeders need to change water immediately to ensure clean water quality. It is best to change water once every 2-3 days, and the amount of water changed each time should be controlled at one third of the total amount of water. If conditions permit, filters can be installed to slow down the deterioration of water quality.
3. The water temperature is low1. Reason: The whitening of red parrot fish may also be caused by the low water temperature. If they live in a low temperature environment for a long time, their body color will also turn white.
2. Solution: Breeders need to raise the water temperature to 25-30 ℃. If conditions permit, it is best to install heating rods to keep the water temperature constant.
4. Scared1. Reason: The whitening of parrot fish may also be caused by being frightened. They are less daring. If they are frightened, their body color will become lighter.
2, Solution: Breeders need to keep their surroundings quiet and wait for them to recover on their own.
