How can I raise fish well, and what are the precautions?

Keeping the water clean is essential, along with providing the right temperature, enough oxygen, and regular feeding. It is safe to keep most species of fish that need to be trapped in water for more than three days. Swallow fish and pineapple fish are stuck in the water for up to seven days.

For most species of fish, the temperature should be controlled between 24 and 28 degrees, and the temperature of swallow fish and pineapple should be 26 to 28 degrees. Below 24 degrees Celsius, fish are susceptible to parasitic diseases. Degrees above 28 degrees will cause hypoxia to "roll the cheeks".

Feed frequently, and feed less each time. In case the fish survives, change to some new water, and the fish will defecate quickly. Changing the water is the biggest trouble in fish farming.

In the absence of a large enough trapped water container, it is still possible to change the water with less frequency, and determine the timing of a complete water change, which is to see that the fins are incomplete, and it is time to change the water. There are ways to change the water without having to change it completely. The water quality is fundamentally guaranteed by spreading coral sand and sprinkling nitrifying bacteria in the fish tank, and the bacteria are activated in large quantities after one month.

Only a small amount of water change is required.

When changing the water of the fish, be careful not to change it all at once, but to throw away a quarter of the original water and then inject new water.

Fish farming must pay attention to the more water, because the more water, the range of fish will expand, and if there is more water, it can ensure that the oxygen content is good, so that the fish can fully absorb nutrients, and you can also install a small oxygen pump. When we raise fish, we should pay attention to the water temperature of the fish tank, we can buy those bathtubs with automatic temperature adjustment, and we can also use the light to increase the temperature in winter.

Buy fish from fish farms and try not to buy fish from fish shops. It is true that you have to buy fish from a fish store, and you have to observe and observe and observe. Observe whether the fish is lively, stay alone or float on the surface of the water for a long time, do not.

Do not have white spots, white filaments, excessive mucus, erythema, fish scales, red or defective gills, red and swollen cloaca, and white stools on the body surface. If there is a fish in a tank with white spots, white filaments, or abnormal gills, you can't ask for fish in this tank, or even the fish in the whole store.

The fish tank should not be placed under the God of Wealth: as the saying goes, "wealth returns to wealth", so the God of Wealth such as Fu Lu Shou Samsung should be placed in the position of wealth, which can be the icing on the cake. It would be a mistake to put the God of Wealth on top of the fish tank.

Because the fish tank should be placed in the residential villain, if the God of Wealth is placed near the fish tank, this will contradict the principle of "wealth to wealth", and if the God of Wealth is placed on the fish tank, then it will be a violation of the Feng Shui taboo of "the god goes into the water", and there will be a risk of ruining wealth? The number of fish to be raised should be matched with the five elements of the head of the household: the number of fish in the fish tank to conform to the Tao of Feng Shui should be determined mainly according to the five elements of the hexagram of the head of the household.

The fish tank should not collide with the stove: the fish tank has a lot of water, and the kitchen stove is fire, because "water" and "fire" collide, so if the fish tank in the living room forms a straight line with the kitchen stove, this is a taboo of water and fire. Hedging between the fish tank and the stove will be harmful to the health of the family; The reason is that water and fire collide, water can overcome fire, and it is the stove that belongs to the fire that suffers, and the family members who rely on this stove to cook will also suffer from it.

In addition, the fish tank should be placed in a straight line with the shrine as much as possible.

The fish tank should not be placed in Jifang: no house can be perfect, there are always some external evils and the like, and using the fish tank to resolve external evils is one of the ingenious methods. In Feng Shui, there is a saying that "water is poured into the zero hall", and the so-called "zero hall" refers to the decline of bad luck, which means that the water is introduced into the direction of bad luck, which can turn evil into good fortune and turn evil into good fortune.

Therefore, the fish tank should be placed on the evil side, not on the auspicious side.

The most important thing is to maintain the oxygen content in the water, and remember to give these things oxygen.

From the perspective of feng shui, it is inappropriate to use water as a backer, because water is impermanent, and it is difficult to find stability by relying on it as a backer. Therefore, if the fish tank is placed behind the sofa and the family sits there every day, it will be reliable and affect the stability of the house. If the fish tank is placed next to the sofa, it will not hinder the feng shui of the house.

Pay attention to two points, one is to change the water, only a part of it can be changed, and the other is to feed less, as the fish are easy to get sick if they eat too much.

Fish should be fed accordingly according to the species of fish, the tank should be cleaned frequently and the water should not be too cold.

Oxygen first. The second is that the environment should not be too noisy, and the water temperature can be well controlled.

Don't feed it too hard, anyway, I'm a good fish, because I feed too much, and I kill myself alive, maybe I'm raising brainless fish.

Change the water of the fish frequently to give it a suitable environment to grow.

1. The water in the fish tank is shallow, the water is shallow and the dissolved oxygen is uniform, and the fish can have more oxygen even at the bottom of the water. If the water is deep, there will be a large difference in the amount of dissolved oxygen above and below the water, with more in the upper layer and less in the lower layer.

2. The mouth of the fish tank should be as large as possible. The large mouth of the tank, the contact surface between the water and the air is large, and the oxygen dissolved in the water is more, which is conducive to the goldfish to breathe more oxygen and reduce the floating head.

3. Fish farming in small tanks should pay attention to controlling feeding, and it is advisable to eat once a day and within 5 to 10 minutes. Feed less on rainy days and don't feed at night. Fish need to consume more oxygen to digest food, and the low air pressure in rainy days and evenings will reduce the oxygen dissolved in the water, so feeding the fish may lead to severe lack of oxygen in the water and the fish will die.

Most of the dead fish occur at night, and severe lack of oxygen in the water is one of the main causes.

Fourth, the bait must be clean. Feeding unclean bait can easily lead to deterioration of water quality, and the deterioration of water will increase oxygen consumption and fish diseases.

Fifth, keep the water clean. Goldfish eat a lot of food, consume a lot of oxygen and excrete a lot of waste, which pollutes the water and exacerbates the lack of oxygen in the water. Therefore, it is necessary to renew a part of the water every day, and it is best to change the water at night to survive the low oxygen period at night.

6. Do not bring greases into the water. The oil will float on the surface of the water to isolate the air, so that the oxygen in the water cannot be replenished, which will cause the goldfish to die of lack of oxygen. Eating meat or applying hand cream to your hands can bring grease into the water and should be carefully avoided.

Water farming: Before raising fish, water should be raised, and the water should be disinfected and dechlorinated. Feeding:

When raising fish, it is necessary to ensure that the food is sufficient and that the food is fed in moderation. Try not to feed at night and on cloudy days. Change the water:

When raising fish, it is necessary to ensure that the water is clean and change the water regularly. Do not change too much water each time, and do not change the water temperature and water quality too much after changing the water. Polyculture:

When raising fish, do not mix lightly. It is recommended to choose fish polyculture with similar habits and docile personalities.

1. Water raising: water should be raised before fish farming. Ordinary tap water cannot be put into use directly.

Water is disinfected and dechlorinated. Disinfection can be done with relevant drugs or with specialized salts. Chlorine can be removed by exposure to the sun or by standing.

It is also necessary to add nitrifying bacteria to the water and establish a nitrifying bacteria system to treat the excrement of fish in the water.

2. Feeding: Ensure that the food is sufficient when raising fish. Pay attention to the appropriate amount of feeding, and the amount that can be eaten within 5-10 minutes of each feeding. The frequency of feeding should be determined according to the appropriate amount of fish raised. Try not to feed at night or on cloudy days.

3. Change the water: When raising fish, it is necessary to ensure that the water is clean and need to be changed regularly. The frequency of water changes is determined according to the habits of the breed raised.

Generally, it should be changed every 7-10 days. Do not let the water temperature and water quality change too much every time you change the water. In addition to ensuring the cleanliness of the water, it is also necessary to ensure the oxygen content of the water.

4. Polyculture: Do not easily polyculture when raising fish. Some fish are not polycultured, and if they are polycultured, they may fight or die. It is recommended to choose fish polyculture with similar habits and docile personalities.

Fish farming should first raise good water, often change the water to maintain water quality, feed food in moderation, food is sufficient and nutritious, polyculture needs to have conditions.

There are many precautions for fish farming, first of all, it is better to change the water frequently, usually it is better to change it once a week, and change a quarter of it each time. The second is to pay attention to the amount of food to feed, so that a small amount of food is done many times, which is conducive to its growth, and it will not spoil the water. At the same time, we should also pay attention to the water temperature, tropical fish must be raised with 20-30 warm water, and the fish tank should be cleaned regularly to discharge the dirt to ensure that the environment in the tank is clean and tidy.

The first thing to do in fish farming is to change the water. Because the water body of the fish tank is limited, the water quality will deteriorate over time, and although the water looks clear, there are many harmful substances, which will increase the risk of fish getting sick, and may also affect their development. Therefore, it is necessary to change the water regularly, usually once a week, and the water quality is maintained well, or it can be changed once every half a month, about a quarter each time.

Fish need to be fed, usually artificial feed, this kind of nutrition is balanced, which is very helpful for the development of fish. It should be noted that although the fish has strong hunger tolerance, it cannot be fed once every long time, and must be fed frequently, two to three times a day, but the amount of feeding each time should not be too large, which is not only conducive to its growth, but also not easy to spoil the water.

Many common ornamental fish are tropical fish, such as guppies, swallows, arowana, etc., and they must pay attention to controlling the water temperature, as too low a temperature will affect their feeding and even lead to their death. Usually the water temperature should be kept between 20-30, although some fish can tolerate low temperatures, it is best not to fall below 18.

The fish tank must be cleaned regularly, usually once a month. Cleaning the fish tank is mainly to discharge the dirt in the tank, and at the same time remove the scale and algae on the tank wall. Be sure to remove the fish before cleaning and prepare fresh water that has been trapped so that you can continue to raise fish after cleaning.

The topic is too broad, today I will only talk about the most important things to pay attention to in fish tank farming;

First, the cleanliness of the water. Fish live in water, water is its living environment, whether it is animals or humans, they need a good living environment. Therefore, the water quality should be kept clean at all times, and it is best to install a filter under the fish tank to filter the fish feces, otherwise the water quality will be very bad if they are mixed together.

The water in the fish tank should also be changed regularly, preferably once a week.

This water can be used from the tap water at home. If the fish live in unclean water for a long time, it will definitely lead to the death of the fish, so the cleanliness of the water is the most important point for fish farming.

Second, the size of the fish tank. Water is the living environment of fish, and the fish tank is the living space of the fish, if you raise the kind of fish with a large size, then you need to have a large fish tank, and they also need living space. Fish also need space to move and breathe, if the space is too confined is not conducive to the life of the fish, so also pay attention to the size of the tank, but this still depends on the type and size of the fish.

Third, sunlight. Plants have photosynthesis, animals also need sunlight, and humans who do not bask in the sun for a long time will be harmful to the body. The fish living in a small space fish tank also need sunlight, so the fish tank at home must be placed correctly, not facing away from the sun, it is best to face the light, so that the fish can also feel the comfort brought by the "sunny day" in every sunny weather.

The most direct harm is the color of the fish, the color of the fish body needs light, so for the health of the fish, and in order to look good at home, it is necessary for the fish to have sufficient light, and when there is sunshine, the fish can also "feel".

Fourth, pay attention to the number of feedings, the fish is not full, you keep feeding, it will keep eating, and then until it dies, so as a fish farmer, you can't feed the fish all the time, under normal circumstances, you can feed it once every two days, don't feed it every day. Fish are already small, and their stomachs don't easily get strangled to death like dogs and cats.
