can fish live without oxygen pumps? If the feeding density is relatively small, the fish can live for a long time without oxygen pumps, but if the feeding density is high, they will die in one to three days, or even faster. Fish live in water, but also need oxygen, if the oxygen content is relatively low, fish will appear loss of appetite, lack of energy and other symptoms, and some will float, so it is best to use oxygen pumps to oxygenate at all times to avoid similar situations.
1, daily oxygen: fish is best to play oxygen every day, oxygen pump can be opened 24 hours, so as to avoid the occurrence of hypoxia. If there are not many fish, it can also be opened in stages, about four hours a day, two hours in the morning and two hours in the afternoon, and two hours in the evening if there are aquatic plants.
2, open crock to hit oxygen: For the person that raises fish for the first time, want to open crock first normally, and also need to hit oxygen in the process that opens crock. On the one hand, it is necessary to ensure sufficient dissolved oxygen in the water body, on the other hand, it is necessary to cultivate nitrifying bacteria, which also belong to aerobic bacteria, so oxygenation can also promote their growth and reproduction.
3. Sick oxygen: If the fish is sick, it also needs oxygen, which can promote its metabolism, thus discharging harmful substances, which is helpful to its recovery. In addition, some drugs themselves will increase the consumption of dissolved oxygen in water, so oxygen supplementation is needed.
