to raise silver arowana, can change water 3-5 days, because they like old water, so the amount of water can not be too large. The frequency of water change of silver arowana is also closely related to the temperature. When the temperature is low, their food intake and activity will decrease. The breeder can reduce the frequency of water change, preferably once every 5-7 days. When the temperature is higher, their metabolism is faster, the speed of water pollution is faster, and the breeder can change water once every three days. When changing water for silver arowana, we should also pay attention to the amount of water changed. They are more sensitive to changes in the environment. The amount of water changed by the breeder should be controlled at a quarter of the total amount of water. Every time the water is changed, the temperature difference between the new water and the old water should not exceed 1 ℃.
1. Young fish: The silver arowana has a large demand for food when it is young. It is better for the breeder to feed it 2-3 times a day until it is 80% full each time. Because their appetite is not large, but the demand for nutrition is large, a small number of feeding can make them develop faster.
2. Adult fish: The adult silver arowana can be fed once a day, because their demand for nutrients will be reduced after adulthood, and their digestive capacity will be weakened, so they can be fed to 70% full each time.
