for goldfish to change after spawning? When goldfish spawn, they will discharge the waste in their stomachs together and pollute the water quality. At this time, they need to change water. In general, half of the water in the fish tank needs to be replaced. However, if the goldfish tank is big enough, only a quarter of it can be replaced. This is because when the fish tank is large, it will dilute the waste they discharge. When changing water for them, it should be noted that the temperature and PH value of the new water should not be too different from the original water. The temperature difference between new and old water should not exceed 2 ° C. Goldfish are suitable for living in water with PH between 6.5 and 7.5. Therefore, the PH of new water should also be within this range. If the difference between the old and new water is too large, it will lead to a sharp change in water quality, which will reduce the resistance of goldfish and affect their health.
? Goldfish do not need to be fed after spawning because they are very weak and their ability to digest food is very weak. If they are fed at this time, it will damage their intestines and stomach, causing them to suffer from enteritis. And at this time, they eat very little food, feeding will not only waste food, but also pollute the water quality. After the goldfish lay eggs, it is best to put them in a quiet place for a period of time, and then feed them after they recover.
