First, prepare the fish tank. Because it is kept in the office, the fish tank doesn't need to be too big. If you put it on your desk, it is enough to prepare a fish tank with a diameter of about 20 cm. Two or three fish are enough. It's too big to look good on your desk. According to your preference, the shape can be square or round.
The newly bought fish tank must be cleaned to ensure a clean and hygienic living environment for goldfish.
Secondly, choose goldfish. It is suggested that it is best to raise koi fish, and koi fish is a cold-water fish, which is easier to raise. You can choose the color you like. The number can be determined according to the size of the fish tank. Just put three fish in a fish tank with a diameter of 20 cm. Don't put too much fish. If you put too many fish, you will easily die of lack of oxygen.
Third, water.
Water is to goldfish what air is to us. Water must be water with high oxygen content. Tap water or well water cannot be used directly. Tap water contains disinfectant chlorine, bleaching powder and other substances, which is very harmful to the respiratory system of fish and cannot be directly used for fish farming. Tap water needs drying for several days, at least one day. This is what people call saving water. Well water belongs to groundwater with high oxygen content, but the water temperature is too low to directly raise fish. It can be dried for a day or two, and it can be used when the water temperature reaches normal temperature.
Fourth, oxygen.
Goldfish also need to breathe and need oxygen. Large fish tanks can be supplied with oxygen through oxygenator, and small fish tanks can be watered frequently. It can be changed every 3-5 days in summer and every 5-7 days in cold weather. Observe whether the fish often go upstream. If bubbles are always spitting on the water surface, it means that the water is short of oxygen and needs to be changed.
Don't change the water every time, just change it by a quarter to a third. If you change too much at once, the fish will not adapt.
Fifth, feeding.
Goldfish don't need to be fed every day, just once every 3-4 days, and don't feed too much at a time. Goldfish don't starve to death, but they die easily. Small fish of five or six centimeters can only feed two or three fish food at a time, or worms, steamed bread, rice grains, dried noodles, fresh fish, shredded pork and the like.
Sixth, deal with garbage.
In order not to pollute the water, it is necessary to deal with the excrement of goldfish in time. You can suck it through a straw, or pour the fish and water into another basin when changing water. After cleaning the fish tank, add a little fresh water, and then put the fish in.
Seventh, beautify the fish tank.
In order to make the fish tank more beautiful, you can put a few smooth and beautiful stones, which can not only beautify the fish tank, but also increase the fun for the fish.
You can also add some aquatic plants, but the water is easy to deteriorate after adding aquatic plants, so inexperienced people had better not put aquatic plants in it.
