Fish live in water, but they also need oxygen. If the oxygen content is relatively low, the fish will have symptoms such as loss of appetite and listlessness, and some will float their heads. Therefore, it is best to use oxygen cylinders to replenish oxygen at any time to avoid similar situations.
First, how long can fish live without an oxygen pump? If the feeding density is relatively small and the fish is not big, it can live for a long time without oxygen pump, but if the feeding density is high, it will die within one to three days, or even faster.
Fish live in water, but they also need oxygen. If the oxygen content is relatively low, the fish will have symptoms such as loss of appetite and listlessness, and some will float their heads. Therefore, it is best to use oxygen cylinders to replenish oxygen at any time to avoid similar situations.
Second, when should oxygen be inhaled 1, daily oxygen inhalation: It is best to give oxygen to fish every day, and the oxygen pump can be turned on 24 hours, so as to avoid hypoxia.
If there are not many fish, it can also be opened in stages, about four hours a day, two hours in the morning, two hours in the afternoon, and two hours in the evening if there are aquatic plants.
2, open the cylinder to give oxygen: for the first time to raise fish, it is usually necessary to open the cylinder first, and oxygen is also needed during the cylinder opening process.
Because on the one hand, it is necessary to ensure that there is enough dissolved oxygen in the water, on the other hand, it is necessary to cultivate nitrifying bacteria, which are also aerobic bacteria, so increasing oxygen can also promote their growth and reproduction.
3, sick oxygen: if the fish is sick, it also needs oxygen, oxygen can promote its metabolism, thereby discharging harmful substances and helping it recover.
In addition, some drugs themselves will increase the consumption of dissolved oxygen in water, so it is necessary to supplement oxygen.
