Gold fish can only live in water, this is the common sense that fish cannot live without water. But not all water is suitable for goldfish life. Therefore, if you want to raise goldfish first, you must raise water first.

Sufficient oxygen In order for goldfish to get enough oxygen, there should be a large water surface. This can increase the amount of dissolved oxygen in the water, and it is also convenient for harmful gases in the water to escape into the air. In addition, it is necessary to keep the water surface clean, so that dust, floating dirt and debris do not cover the water surface and hinder gas exchange. There should be a certain amount of phytoplankton in the water with a little organic matter for raising goldfish, and the water without organic matter and phytoplankton is not good water for raising goldfish. Various phytoplankton and goldfish should maintain a relative balance in the water. If the quality and quantity of some phytoplankton change, such as the water temperature is too high, the sunlight is too strong, all make the phytoplankton flourish and cause the oxygen content in the water to drop. At this time, water with a slightly lower water temperature should be added to relieve it. Too much organic matter in the water is not good for fish life. It will decompose quickly, so that the content of ammonia in the water will increase sharply, which will cause the death of goldfish.

The temperature is suitable for fish, which are ectothermic animals. Their body temperature often changes with the environmental temperature. The water temperature is lower than 12℃, the metabolism of goldfish is slow, and the growth is basically stagnant: the water temperature is higher than 30℃, the activity of goldfish and the Food intake is also affected.

As mentioned above, the temperature can be measured, but two fish experts said: Look at the water first, look at the fish, under normal circumstances, goldfish swim freely in the water, sometimes diving to the bottom of the tank, moving Most of the range is in the middle of the water. If you sink to the bottom of the tank or float on the surface for a long time, either the fish is sick or the water has deteriorated. If the goldfish moves rapidly up and down in the water, and the fish body swings greatly, it means that the water changed is raw water that has not been set aside, or the water temperature may be too low, and the ammonia content in the water is high

For family raising goldfish, place the aquarium in a ventilated and sunny place near a window. Pay attention to the stocking density, and make reasonable arrangements according to the size of the container. It is better to raise less than more. Because the indoor air is not well ventilated, it is easy to become cloudy if you raise too much water, and it is easy to cause the goldfish to die due to lack of oxygen. If you have an air pump, you can raise more. If you find that the goldfish has a floating head phenomenon, you need to open the air pump for oxygenation, especially at night, you need oxygenation.

The ideal bait for family fish farming is live fish and insects, and the water quality is not easy to deteriorate. It is also possible to feed dry fish and insects and synthetic pellet feed. Now there are live fish and worms on the market, but it is very troublesome to buy them every day. For dried fish and worms sold in the market
