One, hit oxygen

1, reason: The commonest reason that butterfly carp turns over belly is anoxic, because they are active, so the demand to oxygen is higher. If the oxygen in the fish tank is insufficient, they will float or turn over.

2. Solution: At this time, the breeder needs to use an oxygen pump to increase oxygen and stop feeding to avoid food residues polluting the water and reduce the oxygen in the water.

Two, keep the water temperature constant

1, reason: Butterfly carp turn belly may also be too large temperature difference, such as late autumn or early spring, morning and evening temperature difference is larger. It is also possible that the temperature difference between the new water and the old water is more than 3 degrees Celsius when the water is changed. If the temperature difference is too large, they will have a stress reaction.

2. Solution: The breeder needs to use a heating rod to keep the water temperature between 18-24 ℃ to avoid the temperature difference between morning and evening. When changing water, the temperature difference between new water and old water should not exceed 3 degrees Celsius.

Three, change water

1, change water reason: If the fish tank does not change water for a long time or the residual food is too much, it will cause the butterfly carp to turn over.

2. Solution: The breeder needs to fish out the food residue immediately and change the water in time. Then increase the filtration in the fish tank and oxygenate it in time.

4, penicillin medicated

bath 1, reason: Butterfly carp turn belly may also be suffering from a disease, the more common is a cold or bacterial infection. The main cause of this disease is excessive temperature difference or poor water quality.

2. Solution: The breeder needs to slowly raise the water temperature to 25 ℃, and then use penicillin to medicate the sick fish. Stop feeding during the medicated bath and change the water every day.
