Arowana should be heated, because they like higher water temperature and need to grow better in high temperature environment. In addition, they have higher requirements for water temperature. If they are not heated, they are likely to have more discomfort. Moreover, arowana grows in low temperature environment for a long time, and it may get sick and die. When raising artificially, it is necessary to install a heating rod to keep the water temperature in a stable range. Only when the water temperature is constant can their physique and growth state be better.

Although they like to live in a high temperature environment, the high water temperature will also cause them more discomfort. The most suitable water temperature for arowana growth is between 26-28 ℃, and breeders need to keep the water temperature between 26-28 ℃ before they can live normally.

Arowana is tropical fish, and its demand for oxygen is relatively high. Breeders had better install oxygen pump for them, so as to ensure sufficient oxygen in water. If breeders don't install oxygen pumps for them, they need to change water frequently to ensure sufficient dissolved oxygen in water. However, they are also sensitive to changes in water quality, so breeders cannot increase oxygen in water by changing water. Therefore, it is best to install an oxygen pump, so as to ensure that there is enough oxygen in their water.
