The arowana is currently a popular ornamental fish, and it needs to be supplemented with enough oxygen when breeding them. Moreover, because they are mainly concentrated in the upper part of the tank, they belong to a kind of upper fish, if they are cultured intensively, they need to provide enough oxygen, otherwise they may affect their normal growth and development. Therefore, one of the equipment that needs to be used in peacetime is the oxygen pump.
Generally speaking, when the number of arowana is very large and very dense, it needs 24 hours of oxygen to provide them with enough oxygen continuously. However, if the number of arowana is relatively small, relatively not particularly dense, then you can take a few hours a day to oxygen, do not need to continue to open all day. If it is open all day, it will not only waste electricity, but also produce noise, which is not conducive to the growth of arowana in general.
The above has been introduced, unless the number of arowana is very large, otherwise they do not need 24 hours of oxygen. However, in some special circumstances, it is necessary to open the oxygen pump 24 hours. For example, if the arowana is sick and needs treatment, in order to make the treatment more effective, it needs to supplement enough oxygen. In similar cases, it is necessary to open the oxygen pump 24 hours to supply oxygen continuously.
