When raising angelfish, providing oxygen is an important step. However, in general, angelfish do not require too much dissolved oxygen in the water. Therefore, in general, oxygen is not needed when farming. However, in some special cases, oxygen may also be needed to provide sufficient oxygen for the organisms in the fish tank. Therefore, when preparing tools and equipment such as fish tanks, oxygen pumps can be prepared in advance and used when necessary.
However, even if you need oxygen, the time is not too long. Oxygen pumps may be used, for example, when angelfish are sick, they need to provide sufficient oxygen, and oxygen pumps can be properly opened to supplement oxygen. Moreover, if the water quality is relatively turbid, the dissolved oxygen will also be reduced. At this time, if there is no time to change water, you can also use oxygen pump to supplement oxygen, temporarily supplement part of the oxygen.
When farming angelfish, water quality is a factor that needs attention. If the water is not changed for a long time, the water quality will be very dirty, and the angelfish will easily get sick; Moreover, the dissolved oxygen in the water will also decrease, and the angelfish may be hypoxic. Therefore, it is better to change it regularly in peacetime. However, the water does not need to be changed too often and there is no need to change it every day. It can be changed once every three or four days according to the specific water quality state, and one third or one quarter can be changed each time. If you don't have time to change water frequently, you can also prepare filters and other tools to clean the fish tank.
