1. Feeding color-enhancing feed 1. Reason: The whitening of parrot fish may be due to lack of pigment, and parrot fish is not a natural product, but an accidental result of crossing different fish. They produce less pigment by themselves, and if the breeder does not supplement them with pigment, the body color will turn white.
2. Solution: Breeders need to regularly and quantitatively feed them with color-enhancing feed to help them synthesize pigments. At ordinary times, we should also feed some rich shrimp, red worms and other foods that can enhance color.
2. Adjust the water quality1. Reason: The whitening of parrot fish may also be that the raised water quality does not meet their requirements, and parrot fish like weak acidic soft water. If the water in which they live is alkaline or hard, they will fade.
2. Solution: Breeders need to keep the PH value between 5.5 and 7.0, and adjust the hardness of water quality to be lower. As long as the water quality they live in is suitable, their body color will slowly recover.
3. Keep the environment stable1. Reason: The whitening of parrot fish may be caused by too much environmental change. Although they have strong adaptability, they are sensitive to environmental fluctuations. If the environment changes greatly, their body color will also change greatly.
2. Solution: Breeders need to keep the water temperature between 25-28 ℃, and the water quality should be clean and refreshing to avoid too much change.
4. Treat it in time1. Reason: Parrot fish may be sick when they turn white. Common water mold, white spot disease, enteritis and cold will cause their body color to turn white.
2. Solution: Breeders need symptomatic treatment according to their performance and etiology. After the disease is cured, their body color will return to normal.
