? 17 degrees will freeze the arowana to death, because the lowest water temperature they can accept in the short term is between 16-18 degrees. If the water temperature is kept at 17 degrees, they will die directly, so the water temperature of 17 degrees will freeze the arowana to death. The favorite water temperature of arowana is 25-28 ℃. The lowest water temperature they can survive for a long time is 20-22 ℃. If the water temperature is lower than 20 ℃, they will lose their appetite. If the water temperature is lower than 18 ℃, they will stop eating, stop moving, and those with poor physique will suffer from diseases. When the water temperature is below 16 degrees Celsius, they are likely to die directly, even if they do not die on the spot, they will die within a week at most.
arowana? The favorite water temperature of arowana is between 25 and 28 degrees Celsius. The breeder needs to use a heating rod to keep the water temperature constant. In winter, when the temperature is low, the water temperature can be kept at 25 C, and in summer, when the temperature is high, the water temperature can be kept at 28 C. In summer, when the water temperature is higher than 28 C, the breeder needs to use ice bags or fans to cool down, because the high temperature will reduce the amount of oxygen in the fish tank, and the arowana will jump out of the tank after hypoxia. And arowana is more sensitive to changes in water temperature, breeders in the change of water or other circumstances, the temperature difference should not exceed 2 degrees Celsius.
