The best water temperature for mini parrot fish is between 25-30 ℃. They belong to small tropical fish and like higher water temperature. If the water temperature in which they live is lower than 20 ℃, there will be problems such as loss of appetite, decreased activity and dim color. Living in low temperature for a long time, they will also have slow growth, poor physique and illness. When culturing artificially, it is best to keep the water temperature above 20 ℃. If conditions permit, it is recommended to keep it above 25 ℃. Although their requirements for water temperature are not very high, they are sensitive to the change of water temperature, so it is best for breeders to install a heating rod to keep the water temperature constant.

Mini parrot fish to be raised with tap water is the best, because they do not require high water quality, and tap water is clean and easy to obtain, so it is more convenient to raise mini parrot fish directly with tap water. However, the tap water just received contains more chlorine, which will have a certain impact on the health of mini parrot fish. Breeders need to expose them to the sun for 2 days before using them.

Mini parrot fish likes weak acidic water quality, and it is necessary to control the PH value between 6.0 and 7.0 when rearing artificially. They prefer fresh water, and breeders can change it once every two days. However, the amount of water changed each time should be controlled at one third of the total amount of water. Pay attention to the temperature difference when changing water. The temperature difference between new water and old water should not exceed 2 ℃.
