of parrot fish for water quality. Parrot fish prefer new water, so it's better to change water once every two days, and the amount of water changed each time should be controlled at a quarter. The best water quality is soft water with weak acidity, and the PH value is controlled between 6.5 and 7.0, because the water quality with weak acidity is more conducive to the color of parrot fish. If possible, it is better to install a filtration system, because parrot fish have a high demand for oxygen, and the filtration system can also increase the oxygen in the water. If conditions do not permit, it is better to change water every day to ensure that the dissolved oxygen in the water and the water quality are clean.
for water temperature is not high, as long as it is between 25-30 degrees, it can survive. But their favorite water temperature is 28 degrees, and breeders can control the temperature to about 28 degrees. If the temperature is low in winter, you can install a heating rod to keep the temperature. It is better to keep the heating rod open all the time, do not open or close it, because it is easy to produce temperature difference. When the temperature is high, you can put the ice bag into the fish tank and fish it out as soon as possible after the temperature drops, so as to avoid the discomfort of parrot fish caused by too low temperature. When changing water, we should also pay attention to the temperature difference not exceeding 2 degrees. If the temperature fluctuates greatly, the parrot fish is easy to fade, and the fish body may also appear black stripes or large areas of black spots.
