Parrot fish 30 ℃ ok. They belong to tropical fish and like to grow in higher water temperature. The most suitable water temperature for their growth is between 25-30 ℃, and the water temperature can be kept at 30 ℃ when they are raised artificially. When the water temperature is kept at 30 ℃, their appetite and activity will become higher, and their metabolism will be accelerated, so it is more appropriate to raise parrot fish at 30 ℃.

Although parrot fish like to grow in high temperature, the water temperature for raising them should not be too high, preferably not exceeding 32 ℃. If the water temperature in which they grow exceeds 32 ℃, they will have decreased resistance and activity.

Parrot fish prefers weakly acidic water, and the PH value can be kept between 5.5-7.0 when cultured artificially. If you want them to grow better, it is best to keep the PH value between 5.5 and 6.0. Because weakly acidic water quality is more conducive to their hair color, making their body color more bright.

However, most tap water is alkaline now, and breeders need to add some substances to adjust the pH value in the water, so as to make the water weakly acidic. If breeders don't want to add chemicals, they can choose to add some olive leaves to the water, which can also make the water weakly acidic.
