Do goldfish need to change the water and feed at night?

Goldfish need to change the water at night, it depends on the density of your fish, if there are more fish and more feeding, change a little water. Feed can be left unfed at night.

It is best not to feed at night, the metabolism is slow at night, it cannot be digested, and it is easy to lack oxygen.

You don't need to change the water every day, you can feed it once every three days, and eat less to avoid death

Goldfish can change the water at night.

Precautions for changing the water of goldfish:

1. When changing the water for goldfish, the first thing to pay attention to is the weather, and it is best to change the water in sunny weather. The water change is usually done at 7 to 8 o'clock in the morning after the sun comes out, or after 3 to 4 o'clock in the afternoon when the sun is in the west. The advantage of changing the water in the morning is that the difference in water temperature is small, and the fish are exposed to sunlight for a long time after the water change, so it is easy for goldfish to create a new environment.

When the water is changed in the afternoon, the water temperature varies greatly. However, in dog days, changing the water in the afternoon has the advantage of adjusting the water temperature and reducing the "stuffy tank".

2. Do not change the water and catch fish when the scorching sun is at noon, especially if the fish are in the old green water, it is not advisable to change the water and catch fish at noon, otherwise the goldfish are very easy to get sick. The reason is: in the scorching sun, the upper water temperature is higher, the bottom water temperature is lower, the fish lying at the bottom of the tank can be protected from the scorching sun and avoid the bad environment of less oxygen, if the water is changed or fished at this time, it is easy to cause internal injury and disease of the fish.

3. After 1 to 2 days of complete water change, the fish will lose their appetite because they are not fully adapted to the environment of Xinpang Town. Therefore, within 1 to 2 days of not changing the water, it is necessary to reduce feeding, otherwise it will cause too many fish and insects and cause the water quality to deteriorate. Within a few days, the goldfish will lose strength and lose weight, or even die suddenly.

4、.The temperature of the water in the tank can be lower than 1 degree Celsius to 1 degree Celsius, and when the water is changed in winter, it can be higher than the water in the tank to 1 degree Celsius.

5. When changing the water and injecting new water, it is necessary to inject it slowly along the cylinder wall, and do not fall down or rush violently, otherwise it will cause the goldfish to catch a cold and suffer internal injuries, causing scale disease and capillary disease.

6. When changing the water, the 2 to 3-year-old adult fish such as precious pearl scales and blisters, especially the mature female fish, should not be fished with a net, but should be scooped up with a spoon or basin with the fish and water and then gently put into the new water, otherwise it is not only easy to touch off the pearl scales or damage the blisters, but also easy to leak eggs and other phenomena.

Time requirements for water changes:

In spring and autumn, it is usually done once every half month or so. In summer, the weather is volatile, the water temperature is as high as 28 degrees Celsius or more, and the water color is very easy to be dark and the water quality is very turbid, so the water should be completely changed once every 4 to 7 days. In winter, the water temperature drops to about 4 degrees Celsius, the goldfish does not move slowly, the appetite is reduced, the water quality is not easy to deteriorate, and the water is generally not changed without special circumstances;

Feeding time requirements:

1. The number of feeding times per day: only 1 to 2 times, the amount of each feeding should be eaten within 1 to 2 hours, the weather and water quality are normal, and the fish stocks with strong hail vitality can be appropriately increased a little bit of feeding;

Because the goldfish eats and comes out at the same time, the water is equivalent to not changing.

Although goldfish is an omnivorous fish completely domesticated by humans, it is the same as other fish such as crucian carp, whether the feed is reasonable and whether the feeding is correct can directly affect the growth and development of goldfish, the depth and brightness of color, the appearance of characteristics, plumpness or not, as well as the number of spawns, hatching rate and disease resistance of goldfish. Therefore, in the feed of goldfish, it must be rich in nutrients such as protein, fat, carbohydrates, various vitamins and a certain amount of inorganic salts and trace elements. For example:

Other conditions are exactly the same, those who can feed enough fresh and live bloodworms every day will have the growth and development of the fish body is particularly large, especially the lion's head, blisters and other characteristics (referring to sarcoma and blisters) are more developed, which may be the reason why bloodworms contain a large number of animal proteins, fats, carbohydrates and other rich nutrients.

You can feed it, but the fish is rectum, and after eating, it will be, and the water that you change is not in vain! The correct way is to feed two or three hours before changing the water, and then change the water when it is almost finished.

To adapt to the new water quality, changing the water and feeding will cause the water quality to fluctuate, which is not good for the fish and even dies.

Relieves stress on the fish's digestive system.
