In the breeding of goldfish, many people will worry about whether the water is hypoxic. If there is a lack of oxygen in the water, it will easily lead to the death of goldfish. Specifically, if the goldfish hypoxia, there may be some specific performance, in these cases after the water on the lack of oxygen, the need to take timely measures.
The most obvious surface for goldfish to lack oxygen is the floating head, which means they may float to the top of the water to breathe. If many goldfish show the phenomenon of floating head, then it is best to take immediate measures, otherwise it may lead to the death of goldfish.
1. After observing the phenomenon of goldfish floating head, you can increase the oxygen content in the water by changing the water. However, the amount of water should not be too much, otherwise the water temperature will change greatly, you can change about a quarter of the water.
2. In addition, some auxiliary tools can be added to the fish tank to increase the oxygen content, such as filters, etc., so that some oxygen can be supplemented in a short time, and no noise will be generated.
3, in the usual maintenance, pay attention to the size of the fish tank, do not use too small fish tank to raise too many goldfish, otherwise the oxygen in the water is easy to reduce. Moreover, to increase the oxygen content in water by changing water regularly, generally speaking, we have to change water once a week or so, about a quarter of each time. In addition, the fish tank has to be cleaned up in time, otherwise goldfish are prone to hypoxia.
4, usually when feeding, not too much, or excess food residues in the water, it is easy to make the water hypoxia.
5. Furthermore, some plants can be planted in the water, and a certain amount of light is provided every day, so that oxygen can be generated.
