Knowledge and precautions of keeping goldfish

First, we should pay attention to "water". As the saying goes, "fish and water" fully illustrates the relationship between fish and water and the importance of water to fish. Clean lake water, river water, well water, spring water and tap water can all be used to raise goldfish. But the well water should be put in the bucket for two days before use, because it is warm in winter and cool in summer, which is easy to make the water temperature in the fish tank suddenly change, leading to goldfish catching cold and getting sick. Tap water contains chlorine and bleaching powder smell, so it needs to be exposed to the sun for two or three days to let the smell run away before use (if it is winter, it needs to be put for two more days). Therefore, general fish farmers are used to using containers to prepare fresh water for standby, rather than finding water temporarily to get it. People who raise fish for the first time often don't understand this truth, which leads to the death of fish.

Second, fish feed. It is best to feed fresh fish worms or dried fish worms. Others, such as rice grains, bread crumbs, steamed bread crumbs and crab seeds (which need to be soaked in boiling water before use), can be used as feed for goldfish. Feed it once a day, after changing water in the morning. Feeding should not be too much (it is easy for fish to overeat and die), so it is better to eat it properly. Don't spend the night in the fish tank, clean it up in time, otherwise it will easily deteriorate the water quality.

Third, goldfish can be raised in glass fish tanks, porcelain pots, pottery pots and cement pools. In general families, glass fish tanks are the best, small in size and suitable for indoor display. Clear and transparent, easy to watch. There are several kinds of glass fish tanks to choose from:

(1) cylinder. Small size, suitable for raising small fish of 5 ~ 7 cm. After adding water to the cylinder, the fish looks fatter and more attractive from the side because of refraction.

(2) Rectangular cylinder. Large size, can raise medium and large fish above 8 cm.

(3) hang the fish tank. For the Yangtze River Delta, one side looks like a picture frame, suitable for hanging on the wall, and still looks like a moving painting. In addition, some pebbles, rockeries, ceramic pavilions, towers and bridges are properly arranged in the fish tank, and some aquatic plants are planted, which is like a beautiful picture scroll, which can increase the viewing effect. Where the fish tank is placed, there should be proper sunshine and good ventilation; Avoid direct sunlight in summer and get more sunshine in winter.

The conditions for keeping goldfish are very high;

1, the fish tank is large, which ensures the activity space of fish.

2. Sufficient oxygen and oxygen cylinders.

3, feeding can not be too much, goldfish do not know how to stop.

4, change water can't be more than one-third.

You'd better not walk around the house. For example, if the weather is fine, you will die.

6. The fish tank in the dormitory is too small, and the anoxic fish dies.
