Who knows how to live by keeping goldfish?

Goldfish should change water frequently, and change water after 24 hours in the sun. This water is rich in oxygen, and many goldfish need nutrition. Don't feed them fish food, because the fish food is inferior and dry, which will lead to the death of the first-class goldfish. It is best to put some plants in the fish tank and feed them to the daily steamed bread. When the sun is shining, put the fish tank in the sun and dry it frequently. Fish live in groups, and one or two of them will die alone On the other hand, fish sellers can only sell fish for a few days. When choosing fish, choose lively golden goldfish instead of gray fish that don't like swimming. Clean the fish tank regularly. I hope my answer will make you feel good. Remember to give me a score.
