What reason is goldfish floats on the back, how to treat

The floating back of goldfish may be due to the deterioration of water quality. When the water quality deteriorates, it will breed a large number of harmful bacteria, causing goldfish to get sick. At this time, appropriate amount of furacilin should be added to the water for sterilization and disinfection. It is also possible that the amount of dissolved oxygen in the water has decreased. If there is a lack of oxygen in the water, they will float on their backs. At this time, oxygen pump should be used to input oxygen into the fish tank. It is also possible that the amount of water exchanged is too large to adapt to the new water environment. At this time, salt should be added to rest for about a week.

One, water quality becomes poor

1, reason: If the water that raises goldfish is not changed in time, the food residue in water or excrement can pollute water quality, breed a large number of harmful bacteria. As a result, increase that risk of disease in goldfish. At this time, they will have the imagination of floating back.

2. Treatment method: When the water quality deteriorates and the bacteria increase, causing the goldfish to get sick, the effect of just changing the water may not be obvious. At this time, the medicinal bath should be carried out in time. 0.2 gram of furacilin is added into 100 kilograms of water, and the mixture is soaked for 15 minutes three to four times a week until the mixture is cured.

2. Less

dissolved oxygen in water 1. Reason: When the oxygen content in water decreases, goldfish will gradually surface to absorb oxygen in water. At this time, there will be a phenomenon of goldfish floating back.

2. Treatment method: When the goldfish is floating on its back due to insufficient dissolved oxygen in the water, the keeper should replace it with new water in time, or directly input oxygen into the fish tank.

3. Excessive water exchange

1. Reason: When the water exchange is too large, goldfish will not adapt to the sudden change of water quality, and then will produce a series of abnormal behaviors, such as floating back.

2. Treatment method: At this time, you can add a proper amount of coarse salt to the fish tank, and stop eating for a week, and wait for them to recover gradually.
