is likely to be caused by poor water quality. The ammonia nitrogen content in the water is relatively high, which leads to the poisoning of fish and the phenomenon of tumbling. In order to improve the water quality as soon as possible, we must change the water regularly, usually every other day, about a quarter of each time.
If the water temperature in the fish tank is relatively low, the fish will be stimulated by cold water, which will also lead to the imbalance of the fish body. Therefore, we must pay attention to temperature control at ordinary times, even for wide-temperature fish, to avoid sudden changes in temperature, it is best to prepare a heating rod, so that the water temperature can be kept at a higher level at all times.
mold after the fish body, the fish will be unbalanced, this time the best treatment is under the salt. Do not put salt directly into the fish tank, it is best to prepare a special container, pour the water into the original tank, then add appropriate amount of salt, fully dissolve, and then soak the fish in it, it will soon recover.
