The fish tank needs to change water regularly, but we must pay attention to the amount and frequency of water change, if the water change is too frequent, or the amount of water change is too large, the fish will be stimulated, and may die. Usually, water should be changed according to the filtration of the water tank. If the water quality deteriorates quickly, it should be changed once a week or a few days. If the water quality is good, it can be changed once half a month.
The fish must not be fed too much. This kind of animal has a strong tolerance to hunger. It will not die even if it is fed once every few days. However, if it is fed too much for a long time, it will easily lead to enteritis, which may cause its death. Generally, it can be fed 1-2 times a day, each time until it is full, and it is advisable not to leave residual bait in the water.
Fish breathe in the water, and if the oxygen content in the water is too low, they will die. Generally, when fish are hypoxic, there will be a phenomenon of floating head, and oxygen should be given immediately after discovery. If there are too many fish in the water, oxygen is needed every day, usually 1-2 hours a day, if it is summer or rainy weather, it can be extended by 2 hours.
If you buy the quality of the fish itself there is a problem, there will be a phenomenon of mass death, so it is best to change the source of fish to buy, find some more reliable and more formal sellers are better, and it is best not to buy online.
