In the normal breeding process, if the filter is open 24 hours, there is no need to use excessive oxygen. Angelfish do not require high oxygen content in the water, so they do not need regular oxygen. However, in some special cases, it is necessary to use oxygen pump in time.
First of all, if the number of cultured angelfish in the fish tank is too large, the oxygen density decreases, and the angelfish floats on the water surface to breathe, it indicates that the tank is anoxic, and it is necessary to inject oxygen in time. Secondly, if the angelfish in the fish tank has some symptoms, such as listlessness, oxygen is also needed in time. Finally, if the water in the fish tank is turbid, debris and floating matter, this situation will accelerate the consumption of oxygen, so it also needs to be cleaned and oxygenated in time.
The angelfish needs a heating rod. Angelfish is a tropical fish, for the temperature requirements are relatively high, suitable for their survival temperature should be between 24 ~ 27 ℃. In winter, if the temperature is too low, it will affect the feeding, or it will threaten its life. Therefore, it is recommended to use heating rods to raise the water temperature in winter.
