The arowana is a very ancient fish with a long history. Today, it is distributed on all continents. It is a tropical fish, and its distribution range is mainly in tropical and subtropical areas of all continents. For example, Asia, Africa, South America and Oceania, etc., have its distribution. It is distributed in the eastern and southern parts of Asia, and it is also popular in China. Because it is a tropical fish, its habits and characteristics are unique, and the requirements for water temperature are particularly high when it is cultured.
As a tropical fish, arowana has a very high requirement for water temperature. Some of the more adaptable arowana, suitable for their water temperature range between 22-31 degrees, but the general adaptation range of arowana is between 24-29 degrees. In the process of breeding it, the water temperature must not be too low, otherwise it will lead to their swimming speed slowed down, appetite will also be reduced. Therefore, if farming in the northern region, in winter, we must pay attention to, if placed indoors with heating is generally no problem, if there is no heating, we must pay attention to adjusting the water temperature, not too low.
In addition, it should be noted that the water temperature for breeding arowana needs to be constant at ordinary times, and can not change dramatically. It can be adjusted to about 28 degrees, which is the most suitable temperature. In order to prevent sudden changes in water temperature, it is necessary to control the flow rate and the amount of water exchange when changing water.
