the lack of oxygen in goldfish? First of all, we should find out the cause of the lack of oxygen in goldfish, so as to solve it better. Goldfish's demand for oxygen is not very high, if there is hypoxia, it may be that the feeding density is too high, the dissolved oxygen in the water is insufficient, there will be hypoxia. In this case, the breeder needs to reduce the feeding density first, and then replace some new water, which can effectively alleviate the lack of oxygen. It
may also be because the water temperature is too high or the air pressure is too low, especially in the high temperature or rainy weather in summer, the oxygen in the fish tank will be consumed faster than usual, so under the normal feeding density, they will also suffer from hypoxia. In this case, the breeder can change the water first, keep the water temperature between 18-22 C. If conditions permit, the oxygen pump can be installed and opened for a period of time every day.
? Goldfish's demand for oxygen is not high, so the time of oxygen every day can be controlled between 2-3 hours. If the temperature is high in summer, the time of oxygenation can be extended. Because the high temperature will reduce the oxygen content in the fish tank, it is necessary to lengthen the time of oxygenation. If the feeding density is high, it is also necessary to extend the oxygenation time, preferably 4-6 hours a day.
