The suitable temperature for parrot fish to grow is between 28-29 ℃, because they are tropical fish and like to grow in warm environment. In this temperature range, their appetite and activity are the highest, and their growth speed and state are also the best. Although they are tropical fish, they can adapt to a wide range of water temperatures, and they can live in water temperatures between 23-30 ℃. However, low water temperature will make them stunted, so it is best for breeders to install a heating rod to keep the water temperature in a warm and stable range.

1. Oxygen: Parrot fish have a high demand for oxygen, so breeders need to install an oxygen pump for them to ensure sufficient dissolved oxygen in their water. If the feeding density is too high, it is best to turn on the oxygen pump 24 hours a day.

2. Feeding: The body color of parrot fish is bright, and the breeder needs to feed some color-enhancing feed regularly, so as to promote their hair color. At ordinary times, you can also feed some rich shrimp, red worms and other foods, and you can also keep your body color bright.

3. Illumination: Breeders should also ensure 2-3 hours of illumination every day, which can not only improve their metabolism speed, but also sterilize and avoid illness.
