can adapt to the water temperature of 25-30 degrees, but their favorite temperature is 25-28 degrees. In this temperature range, the activity and appetite of red parrot fish are the highest. If the water temperature is higher than 30 degrees, the activity of parrot fish will be reduced, and there is the possibility of hypoxia. If the temperature is below 20 degrees, the parrot fish's resistance will decrease, they will get sick more easily, and the long-term low temperature will also affect their growth rate. Therefore, when raising parrot fish, it is better to maintain the appropriate water temperature, and the heating rod can be used continuously to maintain the temperature in winter when the temperature is low.
. Red parrot fish like weak acidic water, because weak acidic water can help them increase their color and make their color more bright. When raising parrot fish, it is better to control the PH value between 5.5 and 7.0. The lips of parrot fish are naturally unable to close, resulting in their greater demand for oxygen, if conditions permit, oxygen pumps can be installed. If there is no condition, you can choose to change the water frequently to increase the dissolved oxygen in the water. When changing water, the temperature difference between new water and old water should not exceed 2 degrees. The amount of water changed each time should be controlled at one third. If there is no filtration system, it is better to change water every three days.
