Feeding arowana can keep the water temperature between 26-32 ℃, but they are sensitive to the change of water temperature, so breeders need to adjust the water temperature according to their growth stage, so as to be more suitable for their growth.

In general, the temperature of newborn arowana needs to be controlled at 30 ℃. Because they are just born, they are not adapted to the external environment. Moreover, they have high requirements for the environment. Breeders keep the water temperature at 30 ℃, which can make them better adapt to the external environment. When they develop for a period of time, the breeder can keep the water temperature between 28-30 ℃. Because they are at this stage, they are the key stage of growth and development, and in this temperature range, their growth state and growth and development speed are the fastest. When they are adults, the breeder can adjust the water temperature to between 26 and 28 ℃.

Arowana likes weakly acidic water, and breeders need to keep the PH value between 6.5 and 7.5. They like clean and refreshing water. When they are farmed artificially, if there is a filter, they can change the water once every 5 days or so. If there is no filter, it takes about 3 days to change the water. The amount of water for Arowana should not be too large, and it is best to control it at one third of the total amount of water. The temperature difference between new water and old water should not exceed 2 ℃, so as to avoid stress reaction caused by too large temperature difference. When changing water for Arowana, it is best to expose tap water for 2-3 days, so as to completely volatilize chlorine in water.
