When should goldfish change water?

The interval between water changes in summer is short, generally 3-4 days to change the water, in spring and autumn, it can be extended to about 1 week, and in winter, it is even possible to change water once a month to half a month. When changing the water for goldfish, the amount of water should not be too much at a time, and a third of the new water can be changed at a time.

Goldfish (Carassius auratus linnaeus), in animal taxonomy.

It belongs to the order Cypriniformes, Cypriniformes, and Cypriniformes.

cyprinidae), the genus Carassius of the subfamily Cypriniae.

Goldfish (carassiusauratus) is also known as golden crucian carp.

Carps evolved from wild red and yellow crucian carp. Far away in the Jin Dynasty.

There is a written record of "red scale fish" - goldfish, which can be called the quintessence of China.

Goldfish are one of the world's three most famous ornamental fish.

One of its kinds, originated in China, has a history of more than 1,700 years.

Goldfish occupies a very important position in China's ornamental fish exports. Goldfish has a beautiful body and a wide variety of species, its body color is red, yellow, blue, purple, black, white, two-color, three-color, five-flower, etc., its body shape has lion head, high head, blister, dragon eye, pom-pom, pearl scales, butterfly tail, tiger head and so on.

The five representative varieties of goldfish are grass gold, red dragon eye, and crane top red.

Blisters, black longevity.

Raising goldfish has long had the experience of "raising fish first and raising water first". Clean water quality is not only conducive to the healthy growth of fish bodies, but also can improve the ornamental value. Therefore, it is necessary to master the technique of changing water when raising goldfish

10 o'clock, or 3 p.mPreferably after 4 o'clock. Do not change the water and catch fish when the sun is scorching at noon, especially for the old green water, it is not advisable to change the water at noon, otherwise it will cause internal injuries and illness of the fish.

In addition, the appetite of goldfish will be reduced after changing the water, so after changing the water, you should reduce feeding or stop feeding for half a day, otherwise there will be too many fish and insects, which will cause fishy changes in water quality, causing goldfish to get sick or even die.

2. Water use: When changing the water, new (excellent) water must be used, and the water temperature difference should not be too large. If tap water is used, it must be dried before use1?

2 days to reuse, or add 2 per square meter of water3 grams of baking soda to neutralize chloride ions in the water body. If well water is used, it is better to use shallow well water to raise goldfish, but it also needs to be dried before use

Use again in 2 days. If you use river, river and lake water, it must be unpolluted and can be used directly to raise goldfish, but the humus and parasites in the water are easy to harm goldfish, so it is safer to use after filtration.

3. Water exchange: The water capacity in the fish tank (pool) should be determined according to the influence of the climate of the four seasons on water quality. In spring, early summer and late autumn, it should not be too deep.

In order to avoid exposure to the scorching sun in hot dog days, the amount of water can be appropriately increased to make the water color appear tender green and prevent scalding tail disease. In winter, the temperature is low, so in order to prevent the bottom from freezing, the amount of water should be larger, and the water color can be green.

Fourth, the method of water change: when changing the water and injecting new water, it should be slowly mixed along the wall of the tank (pool) according to the amount, and it should not be poured or rushed, let alone flushed into the fish body, otherwise it is easy to make the goldfish catch a cold and internal injury, causing diseases such as fried scale disease and capillary congestion.

5. When changing the water, it is not advisable to use nets to catch 2-3 year old adult fish such as precious pearl scales and blisters, especially mature female fish. The spoon or basin should be used to scoop up the fish with water, and then gently put it into the new water, otherwise it is not only easy to touch off the pearl scales or blisters, but also easy to leak eggs.

I have raised a fish for two years and it has not died, and the water is usually changed once every two weeks or so, and the water change is directly added to the tap water, and the time to change the water is generally around two o'clock.

Can't I change the tap water immediately?

There is no time limit for changing the water for goldfish, and if the keeper has time, he can choose to change the water after feeding. Because they pollute the water quality when they eat, changing the water after feeding can slow down the rate of water deterioration. Alternatively, you can choose to change the water at noon on a sunny day.

Because the temperature at noon is relatively high, the goldfish will adapt faster after changing the water. In addition, goldfish are more suitable for old water farming, so the frequency of changing the water for them does not need to be too high. <

There is no time limit for changing the water for goldfish, and the keeper can decide according to his actual situation. If the keeper has enough time, he can choose to change the water after feeding. Because goldfish pollute the water when they eat, changing the water after they have eaten can slow down the rate of water deterioration.

Breeders can also choose to change the water at noon when the weather is clear, because the temperature is higher at noon, and the sunny temperature is more stable, which can reduce the discomfort of the goldfish after the water change.

1. Frequency of water change: The frequency of goldfish water change needs to be determined according to the water temperature, if the water temperature is high, it needs to be changed once every 3-5 days. Because the higher the temperature of the water, the faster they metabolize, and the water is more likely to become dirty.

If the water temperature is low, you can change the water every 7 days or so. Because the water temperature is low, their appetite and activity will be reduced, and their pollution of water quality will be reduced.

2. Water exchange: As mentioned above, goldfish prefer to say the same thing, so the amount of water change should not be too large for each feeder. Under normal circumstances, the amount of water change can be controlled at one-third of the total water volume at a time.

3. Replacement water: Goldfish do not have too high requirements for water quality, and breeders can choose to use tap water for breeding. However, the freshly picked tap water contains a lot of chlorine, and the keeper needs to expose it to the sun for 2-3 days to allow the chlorine to completely evaporate.
