Arowana is a fish from tropical Asia. They live in warm waters in the natural environment, and the water temperature is usually between 24 C and 28 C.. Such water temperature conditions can promote the normal physiological function, immunity and appetite of Arowana. If Arowana is placed in a low water temperature environment, its metabolic rate will decrease and its digestive ability will weaken, which may cause health problems and even endanger life.

In addition, Arowana has higher requirements for water quality. They require clean and stable water quality conditions, including appropriate pH value and appropriate ammonia nitrogen and nitrate. Cold water environment often leads to unstable water quality, and it is easier to produce harmful substances such as ammonia nitrogen and nitrate. These are not conducive to the health and survival of Arowana.

In addition, it should be noted that Arowana has high food selectivity. They like to eat small benthos, such as zooplankton, small invertebrates and benthos. In cold water environment, the number and diversity of these benthos may be limited, resulting in an unbalanced diet of Arowana.

Nevertheless, Arowana has the ability to adapt to a certain range of temperature changes. In some cases, Arowana may be able to survive at lower water temperatures, but this does not mean that they can live healthily in a long-term cold water environment. Long-term exposure to unsuitable low temperature will lead to the decline of immunity of Arowana, and make it vulnerable to infection and disease.
