Is the death of goldfish related to Feng Shui? What is the cause of goldfish's death?

The poor maintenance of goldfish is mainly related to the water quality: before changing water, take some water and put it in the same environment as the fish tank to keep the changed water in the fish tank consistent with the original water temperature. If the temperature difference is too large, the fish will catch a cold. It takes at least one day and night to store water in winter, and at least 12 hour in other seasons. First, keep the water temperature consistent; The second is to discharge some additives in tap water in the natural environment. Every time you change the water in the fish tank, you should try to disturb the fish as little as possible. Use a plastic hose to suck out the impurities in the bathtub by siphon principle, and slowly add water. No more than half of the water is changed in summer and no more than one third in other seasons. Just feed it once a day, and the amount should be controlled within 10 minute. Too much food will affect the cleanliness of water, and goldfish will die if they are not hungry.
