In the process of breeding golden koi, it is often encountered that the fish does not eat food, which also causes headaches for many aquarists. The reasons for this situation are roughly as follows:

1. Water quality or temperature changes too quickly, such as increased ammonia in water, or due to pool transfer.

2. There are parasites on the body surface, such as the front of the long worm The golden koi tend to be restless for a few days, swimming around wildly and being frightened by the slightest noise.

3. The weather changes abruptly, especially in hot and humid weather, lack of oxygen in the water, etc.

4. Drug stimulation, sometimes this happens to golden koi after using drugs, especially insecticidal drugs.

5. Sudden shock, such as turning on the lights at night, etc.
