Skills of keeping goldfish

Mineral water in the natural environment cannot be directly used to raise goldfish. Pure water can raise goldfish completely, but the cost is too high and it is unnecessary.

The reasons are as follows: First, mineral water in the natural environment contains too many minerals, especially calcium and magnesium ions, which are used to raise fish. Second, calcium and magnesium ions will gradually form precipitation in the fish tank, which is difficult to remove after scaling. When these scales are serious, they will even affect the heat dissipation of heaters and the growth of aquatic plants. It can only be used after treatment.

Secondly, it is completely possible to raise goldfish with pure water. However, it is not necessary to raise fish with pure water. After all, pure water costs more. Generally, it is enough for a city to put tap water for two days to let the chlorine in it volatilize and the water temperature automatically rises and falls to about the level of fish tank water.

Extended data:

Goldfish originated in China, also known as "golden crucian carp", which is similar to carp, but has no mouth whiskers. It is an ornamental fish evolved from crucian carp. There are many varieties of goldfish, and the colors are red, orange, purple, blue, ink, silvery white and five flowers. , divided into four strains: literary species, grass species, dragon species and egg species. 12 century, the genetic research of goldfish domestication began. After a long period of cultivation and continuous optimization of varieties, goldfish from all over the world are now directly or indirectly introduced from China.

The skills of keeping goldfish mainly include the following points:

1. Picking fish well is one of the basic skills of keeping goldfish. When choosing fish, you should choose those that look round and bright. This is a healthy fish with good genes. The number of fish should match your own tank. The ideal ratio of water to fish should be 1000: 1, and the length of goldfish and fish tank should be above 1: 10, so as to ensure the good water quality and sufficient dissolved oxygen of goldfish.

2. Keeping water well is the second basic skill of keeping goldfish. Open the tank one week before taking the goldfish home, raise the water and put a few small fish into the tank to see if it is suitable for goldfish to survive, thus establishing a nitrification system. A filtration system must be installed in the fish tank to maintain the water quality. It is also necessary to install an oxygen pump so that the fish can breathe better.

3. The choice of light is one of the important skills in keeping goldfish. After the fish enters the tank, put the fish tank in a sunny place 1 ~ 2 hours. This can use the ultraviolet rays of the sun to sterilize and reduce diseases. Fish diseases should be mainly prevented, supplemented by drugs. And it will make fish colorful.

4. The correct feeding method is the key skill to raise goldfish. To know what goldfish eat, although goldfish are not picky about food, don't buy inferior gold feed. Food includes animal feed and plant feed. Animal feed is rich in protein, but it can't be fed all the time. You also need to match some plant feed, so that the nutrition will be balanced. You can make your own fish food after long-term fish farming, which is both economical and nutritious. Feeding less than more, feeding 1 ~ 2 times a day is enough. Only in this way can goldfish grow healthily and beautifully.

The correct method of changing water is also one of the skills of keeping goldfish. Changing the water once a day can increase the dissolved oxygen in the water, but don't change it all, so the fish can't adapt. It's best to salvage fish excrement and leftover food before changing water every time. If it is salvaged, it is replaced with110 water every time. If it cannot be salvaged, replace it with 1/3 water.

Skills of fish farming

Fish farming needs to manage the fish tank first. The fish tank should be the right size, neither too big nor too small. Pay attention to changing the water at ordinary times, usually once a week, about a quarter at a time, so that the newspaper will be fresh.

Besides, feed it. According to different fish species, we should choose more suitable feed. Carnivorous fish can feed shrimp or fish worms, and omnivorous fish can accept vegetarian food.

Nowadays, many people like to keep some ornamental animals and plants as decorations at home, and goldfish is the choice of many people. Because this kind of fish is very ornamental, it must be raised correctly, otherwise it will be difficult to feed. So how can we raise goldfish well?

The first is to choose fish. A good goldfish looks full, with rounded ends, symmetrical fish body, complete scales and rich colors. You must also choose lively goldfish. Healthy goldfish have stronger adaptability to the environment.

Then there is the fish tank. To raise goldfish, you must prepare a larger fish tank. The specific situation depends on the size and quantity of goldfish to be raised.

Don't worry about putting the newly bought fish directly into the "new home". You can put the fish bag and goldfish in the water tank together, then turn off the lights to let the fish adapt to the environment and water temperature slowly, and then open the fish bag to let the fish move freely.

Feeding is the key to how to raise goldfish. Although goldfish are omnivores, we should pay attention to the reasonable collocation of nutrition in diet, and don't feed them too singly. Also control the feeding amount, because goldfish are easy to die, I would rather not feed for a few days than feed too much.

Then there is the problem of water quality. It is necessary to timely and reasonably change the water and clean the filter cotton. Salvage excess bait and fish excrement in time to reduce water pollution.

Water skills

1; Clean the transparent fish tank first.

2; Use soda water. If there is no soda water, you can use cold boiled water instead. But remember never to use tap water, because there is disinfectant chlorine in tap water, and small goldfish can't eat it.

3; Drink as much water as possible to ensure good oxygen content and full freedom of fish. It's best to buy a small air pump for fish farming.

Feeding skills

1; If you don't have the conditions to keep the water temperature in the fish tank, you should always give the goldfish plenty of sunshine in this cold winter.

2; Put some rice grains and some aquatic plants in the fish tank, but remember that the aquatic plants must be in moderation.

3; When feeding, you can throw some fish worms or white-flour steamed bread, but you should feed less and more each time.

In addition, it should be noted that small goldfish are particularly prone to white spot disease. If you find something like this on the fish, or there is a wound when the scales fall off, remember to buy a kind of "yellow powder" at the flower and bird market, and then drop some methyl blue liquid medicine when changing the water for the fish. Under your careful care, the little goldfish will definitely bring you the same happiness.

Methods and skills of fish farming

Selection of fry: Before raising fish, fry with strong physique, no disease, no injury and sensitive response should be selected. Over-water throwing: put the bag containing fish into the tank for soaking, and put the fry into the fish tank after they adapt to the environment. Feed and change water: change water once a week, the amount of water changed is one third of the total, and feed once a day.

How to raise fish?

1, select fry.

Before raising fish, fry with strong physique, sensitive reaction and no disease or injury should be put into the fish tank. During the selection process, the head, eyes and tail of fish can be observed, the head, eyes and tail of healthy fish will not be injured, and the scales will not fall off.

2. Send water

In the process of throwing fry, it is necessary to take measures of flooding. Put the bag with fry directly into the fish tank, and after the water temperature in the bag is close to that in the tank, pour the water in the tank into the bag. After the fry adapt to the environment, you can cut the bag and let the fry enter the fish tank.

Step 3 feed and change water

In the process of fish growth, the requirements for water quality are higher. During the breeding period, the water should be changed once a week, and the amount of water changed is one third of the total water to prevent the fish from being unable to adapt to the environment. Moreover, before changing tap water, tap water should be dried 1 day to remove chlorine. Generally, feed the fish once a day, and don't feed too much each time to avoid the fish dying.

Introduction to fish farming skills

Introduction of fish culture skills, fish culture is not as easy as it looks, especially for beginners, fish culture is a very difficult thing, so how to raise fish well? Next, I will introduce some fish farming skills, and I hope this fish farming skills introduction can help everyone.

Introduction to Fish Culture Skills 1

One of the most common mistakes made by novices: round/irregular fish tanks for fish farming.

The most common aquarium in the aquarium market is the round aquarium. Many novices buy this kind of fish tank for the first time, but this kind of fish tank is a serious injury to fish farming.

Cause of error: Circular and irregular fish tanks can't be equipped with necessary equipment such as filters and heating rods, which leads to the water in the fish tank can't form circulation and biochemical action and become stagnant water. At the same time, because the surface is round or irregular, it is distorted when enjoying, and long-term feeding will lead to the decline of fish's vision. Therefore, raising fish is actually abusing fish, and it is strongly recommended that fish farmers do not use this kind of fish tank.

The second common mistake made by novices: raising fish in three tanks.

Can containers and water be used to raise fish? This is a misunderstanding.

Wrong reason: fish farming needs to filter the water body to keep it clean and clear, and tropical fish need proper water temperature to grow healthily. We need to know the change of water temperature in the fish tank through the reading of thermometer, which is often overlooked.

Solution: Choose a square fish tank and add necessary equipment for the fish tank. Let's take a look at the three artifacts necessary for raising tropical fish!

Artifact 1: Elbow Sword-Filter.

Artifact 2: Tu Longdao-heating rod.

Artifact 3: Kongtong Seal-Thermometer

The third mistake that beginners are most likely to make: using colored stones, simulated aquatic plants, corals and other landscaping.

The color of the fish tank is very monotonous. We usually want to add a color to the fish tank, but it is relatively difficult for beginners to plant aquatic plants, so it is easy for us to buy some colored stones, simulated aquatic plants, simulated corals and other objects to put in the fish tank.

Reasons for errors: 1. Most aquatic plants, corals, etc. They are all made of plastic materials, which are easy to release harmful substances when soaked in water for a long time, especially in the environment with high water temperature. At the same time, due to the low price and uneven quality of simulation items, some simulation items with poor quality are easy to scratch the fish skin and cause infection. However, colored stones, simulated aquatic plants, etc. Mostly colored. If the dye is sprayed or injected, the dye will volatilize toxic substances in the water, which will easily lead to chronic poisoning of fish. Over time, the fish will suddenly and inexplicably die.

Solution: Say no to dyed items and simulated items!

The five most common mistakes beginners make: tropical fish mixed with cold water fish, big fish mixed with small fish.

Some students like both peacock fish and small goldfish, so they happily put them in the fish tank together, but after a few days, either the peacock died or the goldfish died. Why? This is the fifth mistake that beginners often make.

Error reason: Peacock fish belongs to tropical ornamental fish, which is suitable for living in water of 24-26 degrees Celsius, while goldfish is cold-water fish, which is suitable for living in water of 16- 18 degrees Celsius. Cold and hot water fish are mixed, either the water temperature is too low to raise tropical fish, or the water temperature is too high to raise cold water fish, and serious death will occur. Therefore, children's shoes must be distinguished, and cold-water fish cannot be mixed with tropical fish.

Solution: Tropical fish and cold water fish are raised separately.

Cause of error: eat small fish, it is a common fact in the fish industry that big fish eat fry. Big fish are mostly wild predators, and they are born quickly. Even if the fish are young when you buy them, they only need a short time to grow into giants. And the big fish is fierce, even if it is still small, it will attack other small fish. Solution: Identify big fish. Big fish and small fish can't be mixed together, including the larvae of big fish.

The most common mistake made by novices is the high feeding density.

Think about whether you like traffic lights, peacocks, zebras and colorful skirts. Not only that, I also want to make the fish not lonely, and bring more small fish home, hoping that they can live in harmony, only to find that the fish are beginning to drift away from you one by one.

Cause of error: A fish tank is full of fish, and the density is too high, resulting in a rapid decrease in dissolved oxygen in the water. At the same time, there is no oxygen-increasing equipment in the fish tank, and the fish gradually die of lack of oxygen.

Solution:

1. Learn a formula to calculate the water volume of a fish tank. Take a 60*45*45cm fish tank as an example, assuming that the water level is 40cm high, then the water volume = 60 * 45 * 40/1000 =108L when the glass is ignored. New children's shoes must remember this formula and learn to calculate the volume of water.

2. For ordinary small and medium-sized fish, an average of 1L of fish cultured in water 1cm is a relatively safe range. Take the fish tank above as an example. If the water body is 108L, the total length of fish in the fish tank will not exceed 108cm. Similarly, if your fish tank only has 10L of water, the total length of the raised fish should not exceed 10cm.

3. The above formula is suitable for small and medium-sized fish. Small fish can be appropriately increased, medium-sized fish are basically calculated according to the formula, high-oxygen fish such as goldfish and parrots are halved, and the feeding density of large fish is determined according to the types of fish.

4. Of course, you can provide dissolved oxygen for the fish tank by adding an air pump, but even if there is an air pump in high-density feeding, it is risky, because in case of power failure, the air pump cannot supply oxygen for a long time.

Commercial fish farming skills

For fish farming with commercial interests, we only need to pay attention to fish farming skills in daily life. General fish farming, as long as it is not designed for home feng shui fish, has nothing to do with feng shui. When we raise fish in commercial mode, we must pay attention to some living conditions and feeding conditions of fish. It is best to start with a small number of samples, or ask experienced fishermen how to raise fish. First, lay a good foundation and prepare for a big fight. Of course, if you have money, you can also ask someone with professional knowledge to help you manage it.

Cultivation skills of ornamental fish

Ornamental fish farming is generally at home, but for fish farming at home, it can not only increase vitality, but also cultivate sentiment and relax pressure. And if you want to appreciate fish farming skills, you should pay attention to some common sense problems.

1. Water change: generally, water is changed once a week in winter and once every two or three days in summer. Every time you change the water, you change it to a quarter of the water in the fish tank. The water temperature for changing water should not be too different from that of the fish tank.

2. Temperature: It is necessary to know the living temperature range and the most suitable living temperature of cultured ornamental fish. Because each kind of fish is different, you can check it online if you don't know.

3, lighting: Generally, many fish are very dependent on light, preferably sunlight, if not, it can also be light.

4, food: breeding ornamental fish Many people will use feed for the convenience of the map. In fact, feed feeding is very easy to cause water quality decline, and water is often changed.

Feng Shui Feeding Skills of Ornamental Fish

As long as you keep fish at home, you will design a feng shui problem, and

1. The number of fish farming must be selected. Generally, it is better to choose a birthday with more heads of households.

2. For the types of fish, generally do not breed some unlucky fish with no good meaning as ornamental fish.

3. The most important thing in fish farming feng shui is actually the placement of fish tanks, which have many precautions. You can look for it online.
