How to change water for small goldfish

Question 1: How to change water for goldfish in ordinary families? Of course you can't raise fish. You don't have to leave the fish tank to change water, and you don't have to change all the water, at most one third. If you replace all the water with new fish, you will die.

Just remember the following simple questions and you can keep goldfish.

1. Goldfish prefer to eat red worms, earthworms and shrimps. In addition to artificial compound bait. To ensure that the bait is fresh, it can't be fed if it goes bad.

2. Goldfish can be fed 1 time a day. Feed them regularly. Goldfish don't know if they are hungry. Feed them 80% at a time and finish them in five minutes.

Goldfish is a cold-blooded animal, so it is not afraid of cold, but since you keep it indoors, I believe the temperature should not be very low. Generally, it is good that the water does not freeze, but try to keep the water temperature constant. If it's hot and cold, you're sure to catch a cold.

4. If there is no filter, suck out the fish dung on time every day, and then add the same amount of trapped water to suck it out (trapped for three days), so that you can only change a little water, keep the water clean, and inject oxygen. A lot of water should be changed once a week or more (or mixed with water), that is, 3/ 1 water can be changed. Before changing water, the accumulated water should be replaced several hours in advance.

Question 2: How can the goldfish change tap water if they can't raise fish directly? There are two reasons. First, because the tap water purified with bleaching powder contains chlorine, it is impossible to raise fish directly. Generally, it is exposed to the sun for 1-2 days. When chlorine gas is completely oxidized and volatilized, it can be used to raise fish.

Secondly, there will be a certain temperature difference between the water temperature of tap water just released and the water temperature of raising new fish, and the water temperature will suddenly melt, making the fish easy to catch a cold.

For goldfish, do not change all the water. All water changes are carried out when the fish tank is polluted. Generally, changing water 1/4- 1/3 is enough. All water changes will lead to drastic changes in water quality, which will easily make fish uncomfortable, irritable, wipe their ass and even die.

Question 3: How to change water for goldfish? Generally, do not pour all the water, leave 3 mouthfuls 1 and add water. If it is dirty, empty it completely, rinse the fish tank, add water and 1-2 pieces of baking soda. If there is no soda, leave the water overnight, so that the chemicals in the water will volatilize, which is better for the fish.

Question 4: Correct water changing method for goldfish 1. When there is no free pool, all goldfish must be caught in the pool, or cages should be put in the water of adjacent pools for temporary cultivation, and inflators should be added to the pool or cage to inflate. Then, brush off the moss on the wall of the original pond, rinse it thoroughly, re-inject isothermal fresh water, let it stand for a while until the water temperature is equal, and then put the fish into the original pond (cylinder).

2. If there are free ponds and fresh water, all the goldfish should be fished into pots or cages, and selected and treated separately. No matter which pond, the goldfish in different ponds can be moved to a new pond for feeding at the same water temperature. This method of changing water should pay special attention to the water temperature, and it is best to choose it before 9 am on a sunny day. However, this method is generally only applicable to adult fish or larger young fish, and young fish should not be used. If possible, it is best to fill the standby pool (tank) with flooded water before completely changing the water, and then fish it directly into the standby pool (tank). In this way, the water temperature changes little, the fish can easily adapt to the new environment, and the fish can be prevented from being squeezed in pots or cages. In spring and autumn, this method of changing water is generally carried out every half month or so 1 time. In summer, the weather is bad, and the water temperature is as high as 28℃, so it is necessary to completely change the water 1 time in 5-7 days. In winter, when the water temperature drops to about 4℃, goldfish move slowly, their appetite drops, and the water quality is not easy to deteriorate. Generally, all water is not changed unless there are special circumstances.

Question 5: How to change water for goldfish? Can I use tap water? I also use tap water to raise goldfish, just like the friend above said. Leave the goldfish for a day or two. Do not feed too much food. You will die if you eat too much.

Water lifting skills:

Quickly establish benign water quality: add water quality stabilizer to tap water and put it into aquarium when the water temperature is the same as that of old water. Release active nitrifying bacteria, and put them into water quality clarifier for filtration after 1-2 days. Then add artificial nitrifying bacteria every week.

Goldfish feed

Goldfish is an omnivorous fish with a wide range of food. This has brought great convenience to goldfish breeding. However, if you want to get a good feeding effect, you must carefully understand the habits of goldfish and the characteristics of various feeds, so that your feeding can be colorful and thrive. Good goldfish feed ingredients should include: protein, fiber, fat, vitamins and trace elements.

Goldfish feed is mainly divided into two categories: aquatic feed and synthetic feed.

Aquatic animal feed includes live or dry aquatic animals and plants that goldfish can eat. Including: Daphnia (commonly known as "red flea"), cyclops (commonly known as "green flea"), blood worm (commonly known as "red worm"), water earthworm (commonly known as "nematode"), duckweed and so on.

In all aquatic animal feeds, practice has proved that Daphnia is the most comprehensive nutrition and the most suitable feed for goldfish. Feeding with Daphnia, goldfish not only love to eat, but also digest well, and the metabolites produced are not easy to be turbid. Moreover, the living Daphnia can also swallow tiny pollutants suspended in the water, thus purifying the water quality (commonly known as "water intake"). However, Daphnia generally depends on the output of nature and is influenced by seasons and weather. Therefore, it can only be purchased in April-165438+ 10 every year, which can't meet the needs of domestic goldfish growth in one year. In addition, Daphnia is not easy to survive and preserve, and it will deteriorate in one day, so it is not easy for busy modern people to feed goldfish entirely by Daphnia. Freezing or drying in the sun can prolong the storage time, but its nutrients will also be lost a lot.

Other aquatic animal feeds are not as comprehensive in nutrients as Daphnia, and often carry germs, which leads to the growth of goldfish. Therefore, disinfection and alternate feeding should be adopted to avoid the above shortcomings.

Feeding tips: Synthetic feed is suitable for feeding goldfish at home. Sliced feed is an ideal feed form. Feed ingredients are very important.

Goldfish-Prevention and Control

The beloved goldfish fell ill and the goldfish he just bought died, which is an annoying problem that almost every beginner will encounter. However, there is no business to treat goldfish in general pet hospitals, so it is very necessary to master one or two methods to treat goldfish. Goldfish get sick because of the following factors. Environmental factors, physical damage, virus infection, etc. The following are my views on the prevention and treatment of these pathogenic factors:

First, environmental factors: goldfish live in water and are very sensitive to changes in light, water quality and water temperature. Especially the change of water temperature, the sudden change of the limit water temperature that goldfish can bear is 4 degrees Celsius. If you exceed this limit, you will get sick and even die. Therefore, it is necessary to pay attention to the change of old and new water temperatures when changing water and tanks for goldfish. In addition, the sudden change of water hardness and pH will also affect the biological protective film of goldfish, which will lead to goldfish getting sick. The correct way is to dry the fresh water for 3 days before changing the water, so that the temperature difference between the water temperature and the old water is within 65438 0 degrees Celsius, and the chlorine in the water is volatilized. Keep the water exchange rate below 1/2, and slowly inject new water. In case of emergency, water quality stabilizer can be added to fresh water to quickly remove harmful substances in water. Add boiling water and measure the water temperature with a thermometer until it approaches the old water. But not suitable for rare varieties. If the light is too weak or too strong for too long, it will also affect the body color and growth of goldfish. Dissolved oxygen in water is also a key factor. Too low dissolved oxygen will cause "floating head", and too heavy will cause suffocation and death. The simplest way to solve the problem of dissolved oxygen is to use the special air pump for aquarium. Select the appropriate power according to the water quantity. In addition, the method of external circulation filtration can also increase the oxygen content in water. Harmful substances produced by goldfish metabolites can be solved by changing water and adding nitrifying bacteria.

Second, physical damage: in the process of moving goldfish, it is easy to cause damage to the body surface of goldfish, which will seriously cause the internal organs of goldfish to rupture and lead to death. In addition, if there are sharp ornaments in the aquarium, such as coral stones and plastic aquatic plants. Blisters will also be punctured and bead scales will be scraped off. Even if the suction of the pump is too strong or the water flow speed is too fast, there is a danger of causing physical injury. Therefore, it is suggested to scoop fish with water when moving goldfish, and move ... >>

Question 6: How to raise goldfish and how often to change water. Fish are often raised with tender green and clean old water, and the fish raised have the largest appetite, strong body, bright color and rapid development. Production method: a pot of clear water is exposed to the sun for one day, then a spoonful of soybean milk is sprinkled in the water (depending on the amount of water) and exposed to the sun for one week.

In spring and summer, 10- 15 days, completely change the water 1 time. In winter, when the water temperature drops to about 4℃, goldfish move slowly, their appetite drops, and the water quality is not easy to deteriorate. Generally, all goldfish are not changed unless there are special circumstances.

If it is found that the old green water in the original tank suddenly turns into clear water, and a lot of green algae are precipitated at the bottom of the tank, this phenomenon is called returning to clear water. This kind of water is easy to cause fish diseases and needs to be completely replaced.

In general, especially in hot summer, as long as110-1/5 is sucked out of the bottom of the fish tank together with old water every day, the dust and floating feces on the water surface are removed, and then isothermal new water is slowly injected along the tank wall to keep the water quality clean. This method of changing water is not easy to hurt fish, simple and safe, and is most suitable for family fish tanks or small ponds.

Partial water change is mainly carried out in two situations. One situation is that in hot summer and early autumn, when the water quality is still relatively clean, all the goldfish in the pond can be fished out, and then the water in the pond can spiral. After a short rest, use a rubber hose to suck up the dirt and old water in the center of the pond to 1/3- 1/2, then inject new water with the same temperature and quantity, and then fish out the goldfish and put them in the original pond for culture.

Prepare a pot of new water the day before changing water.

Oh, I'm exhausted.

Question 7: How to change the water for small goldfish Novices often ask when to change the water for goldfish. According to an online survey, some people say that water should be changed every day, and some people say that goldfish can't change water often. In fact, these two statements are not correct, because the purpose of changing water is to change bad water into brand-new water, so it should be that water is not bad, that is, water should not be changed. Because every time we replace some bad water with the same amount of new water, it is called water.

So what are the signs of broken amniotic fluid?

1. It was mentioned earlier that goldfish often float because of water quality problems, low dissolved oxygen in water, and fish feel suffocated, so goldfish float.

2. The water quality is unclear. Too much bait and unclear residual bait lead to turbid water in the tank. There may be nothing wrong with the fish for the time being, but the water should be cleaned up as soon as possible.

3. The water is too green, the water in the tank is not inflated, and the goldfish in the tank is easy to get hot tail disease, and floats on the water when the sun shines again.

4. The fish doesn't behave normally, so it turns over without eating.

Question 8: How to raise goldfish without changing water? Hello! The predecessors of goldfish breeding have long had the experience of "raising fish first and then raising water", which shows that the quality of water quality will directly affect the normal growth and development of goldfish. The purpose of changing water is to remove the dirt (garbage, fish manure, excess feed and stale impurities) in the water, keep the water clean, adjust the water temperature and increase the oxygen in the water, thus promoting the growth and development of goldfish. If you want to raise goldfish well, you must have a preliminary understanding of fish culture water: 1. Raw water refers to tap water or well water that has just been released and has not been completely dried. Its water temperature is often quite different from that of fish ponds (tanks), and contains more chlorine, which is very harmful to goldfish. 2. Fresh water is tap water, well water and spring water. After drying and standing for about 2-3 days, the water temperature is the same as or similar to that of fish ponds (tanks). 3. Old water is dirty water with feces and dirt at the bottom of fish ponds (tanks). Including the water supply that has not been replaced for a long time in the pool (cylinder). 4. Old water is the general name of clean water in fish ponds (tanks) that is tender green, green, old green or brown green. Among them, light green water is the best. There are many green algae floating in the old water, which is also a good auxiliary feed for goldfish. This kind of water decomposes less organic matter and more dissolved oxygen, and it is often used to raise fish with tender green and clean old water. The fish bred have the largest appetite, strong body, bright color and rapid development. 5, back to clear water If you find that the old green water in the original pool (tank) suddenly turned into clear water, a lot of green algae precipitated at the bottom of the tank, this phenomenon is called back to clear water. This kind of water is easy to cause fish diseases and needs to be completely replaced. (1) Under normal water exchange conditions, especially in hot summer, as long as the feces and dirt at the bottom of the fish pond (tank) are continuously sucked out with a hose every day,110-1/5, the dust and floating feces on the water surface will be removed, and then along the pond (. This method of changing water is not easy to hurt fish, simple and safe, and is most suitable for family fish tanks or small ponds. (2) Partial water exchange is mainly carried out in two situations. In one case, in the hot summer and early autumn, the feed water in the fish pond (tank) has been changed for several days, but the water turns green quickly (due to a small amount of feed), and the water quality is still clean. Therefore, in order to prevent goldfish from scalding their tails, all the goldfish in the pond (tank) can be fished out, and then the water in the pond (tank) can be rotated into a spiral shape, and the pond (tank) can be put to rest for a while. Another situation is that the water in the pool (tank) has only been changed for a few days, and the color of the water is still good. However, due to excessive feeding and floating head, emergency measures must be taken. The method of changing water is the same as that mentioned above. If it is a big fish pond in a fish farm, you don't need to fish out the goldfish, but enclose the fish with a folding screen, and then gently rotate the water in the pond with a fishing net for dozens of seconds. When the water is still for a while, start the drain gate to drain slowly, or suck excess fish, feces and old water from the center of the pond (tank) with a straw, or use a fishing net bag to pick up excess fish and insects from the center, and then release 1/4. (3) Completely changing water This water changing method is often a combination of turning over the pond (tank) and selecting young or adult fish. It is often used because the water quality is seriously deteriorated or the moss is too long and the fish is too dense. There are two methods: 1. If there is no free pool, we have to fish all the goldfish into the basin or put the cage in the water of the adjacent pool for temporary cultivation, and add an oxygen-increasing head to the basin or cage to increase oxygen. Then, brush off the moss on the wall of the original pond, rinse it thoroughly, re-inject isothermal fresh water, let it stand for a while until the water temperature is equal, and then put the fish into the original pond (cylinder). 2. If there are free ponds and fresh water, all goldfish should be caught in pots or cages, and selected and treated separately. Goldfish can be moved into fresh water and fed in sub-ponds, regardless of water temperature. This method of changing water should pay special attention to the water temperature, and it is best to choose it before 9 am on a sunny day. However, this method is generally only applicable to adult fish or larger young fish, and young fish should not be used. If possible, it is best to fill the standby pool (tank) with flooded water before completely changing the water, and then fish it directly into the standby pool (tank). In this way, the water temperature changes little, the fish can easily adapt to the new environment, and the fish can be prevented from being squeezed in pots or cages. This method of changing water is generally carried out every half month in spring and autumn 1 >>

Question 9: How to change the water in the goldfish bowl! Goldfish like old water and don't need to change it often. Green water is good for goldfish! If there is a filter, there is no need to change it. If there is less water, add more. If there is no filter, just remove the fish feces and add the same amount of water! Don't feed the goldfish too much, or the water will get dirty soon! Granular feed only feeds one fish a day! The water must be trapped at least three days in advance! Don't hit the fish when adding water, and the temperature difference between the added water and the water in the original tank should not be too big.

Question 10: How to raise goldfish? Requirements of goldfish culture on water quality.

As the saying goes: "fish farming should first raise water." If you want to raise goldfish well, you must first have a full understanding of the water environment suitable for goldfish to grow.

Goldfish is a kind of wide-temperature fish, which can adapt to a wide range of temperature and can survive in water temperature of 0-38 degrees. The optimum growth temperature is 20-28 degrees. When the water temperature exceeds 30 degrees, people will feel uncomfortable, and the mortality and morbidity will increase significantly. When the water temperature is below 4 degrees, they will start to sleep. Although goldfish can adapt to a wide range of water temperature, it can't stand the instantaneous change of water temperature. Generally, the daily temperature difference does not exceed 10 degree, and the instantaneous temperature difference does not exceed 1-2 degree. Therefore, the goldfish just bought together with the package should be put into the water 1-2 hours, and the water temperature inside and outside the package should be consistent before being put into the tank for feeding.

Requirements of goldfish for water quality.

Goldfish require the ph value of water to be 5.5-9.5, but prefer neutral and alkaline water, and the suitable ph value is 7.5-8.5. Cl ion in water is also one of the factors that can lead to goldfish poisoning and death, so the tap water for goldfish breeding should be used in the sun for about 24 hours or 2-3 days, or sodium bicarbonate can be put in the water to remove Cl ion.

Dissolved oxygen in water is another important factor affecting the growth of goldfish. Its lack will lead to slow growth, floating and even death of goldfish. Therefore, when the dissolved oxygen in water is low in rainy days or at night, the aerator should be turned on for aeration.

Water temperature, ion content and dissolved oxygen in water are three major factors affecting the living environment of goldfish. Grasping these three factors well can create a warm and comfortable living environment for goldfish.

Matters needing attention on how to change water for goldfish

Goldfish is a typical ornamental fish, and its living environment depends entirely on artificial provision. If the artificial environment is not suitable, it can't survive. Goldfish generally live in a fixed small environment, which is unstable and changes at any time. For example, after neutral water (pH 7) is put into the fish, the fish continuously discharges feces and food residues into the water, and after the action of bacteria, it continues to rot, and the water quality becomes slightly acidic, so the neutral water only exists for a short time. Other conditions, such as water temperature and dissolved oxygen, are constantly changing under the influence of the external environment. In order to ensure the normal life of goldfish, it is necessary to adjust the water quality by changing water. How and when to change water for goldfish is an important work in goldfish breeding, and whether this work is done well is the key to the success or failure of goldfish breeding.

Daily water change should pay attention to the following points:

(1) in the pool (or cylinder, basin, box, etc. ) In the place where the water is to be dried, the newly taken cold water is stored and dried for 2~3 days, so that all kinds of impurities in the water precipitate, chlorine gas volatilizes, and the water temperature rises to the same temperature as the fish pond before it can be used as exchange water for fish farming.

(2) The amount of water exchanged depends on the season and water quality. For example, in spring, the water temperature is low and the dissolved oxygen in the water is high, but the oxygen consumption of fish is low, so the amount of water exchanged at this time is only110 of the total; With the increase of temperature, fish have a large activity, vigorous metabolism, large food intake and increased excreta, and the water exchange rate can be increased to about 3/ 10. In summer, the water temperature in fish ponds rises, and the oxygen consumption of fish also increases, so goldfish are easy to "float" due to lack of oxygen. At this time, the water exchange rate should be increased. In addition, it is necessary to lower the water temperature, properly exchange a certain amount of cold water, or set up a sprinkler or start an air pump. If the water smells or is pink, it is best to replace it all. Generally speaking, it takes a few days for fish to adapt to new water before they can eat normally. In general, it is not necessary to change all the fish into new water.

(3) It is best to change the water after 4 pm, when the fish swim a little after dinner. Before changing water, clean up the residue in the pool before adding new water.

(4) When changing water, don't pour it, don't rush it, and don't rush the water to the fish's body to hurt it.

Change the water for goldfish every few days.

The predecessors of goldfish breeding have long had the experience of "raising fish first and then raising water", which shows that the quality of water quality will directly affect the normal growth and development of goldfish. The purpose of changing water is to remove the dirt (garbage, fish manure, surplus feed and stale impurities) in the water, keep the water clean, adjust the water temperature and increase the oxygen in the water, thus promoting the growth and development of goldfish.

If you want to raise goldfish well, you must have a preliminary understanding of fish culture water:

1. Unpurified water

Refers to tap water or well water that has just been discharged and has not been dried. Its water temperature is often quite different from that of fish ponds (tanks), and contains more chlorine, which is very harmful to goldfish.

2. Fresh water
