Why do goldfish always die?

I had this problem when I first started raising it. After 9 attempts, the following experiences were summarized:

1, don't feed frequently, goldfish are easy to be bitten to death. If you buy special fish food, be sure to soak it in a small bowl for about 2 hours, and then break it according to the size of the fish before feeding it. Direct feeding will lead to the direct death of fish food soaked in fish belly.

2, the cleaning of the fish tank, the fish tank should not be too clean, the water is self-cleaning and there is no fish. Keeping nails bright and changing water frequently is not good for fish. As long as there is no hypoxia, change it once every 3-5 days in summer and once every 7- 10 days in winter. Of course, it depends on the size of the cylinder. The larger the cylinder, the longer the time. Mine is 12 inch diameter, which is changed every four days. If the fish is not sick, don't use sterilized things. The symptoms of fish illness are different colors of phosphorus.

3, water, do not directly change with tap water, put it in a bottle and dry it on the balcony for a day, because the disinfectant inside is harmful to fish. Also, pour a small bowl of water before changing the water, put the fish in, and return the bowl of water together after changing the water.

4. Don't use those plastic fake aquatic plants. If the jar is big, use real grass; If it's small, write stones. It's best to use natural stones picked up at the construction site.

Why did goldfish die?

Lack of oxygen is the main reason, and there are other reasons, such as virus, water temperature and some problems. To raise fish with tap water, it is necessary to dry the water for a few days to remove some antiviral substances from the water.

Fish are not easy to die in winter, so be careful not to give them too much food, they are easy to swell to death.

Why do goldfish die so easily?

Fish water should be dried in the sun for a few days to remove chlorine, and then the fish should not be fed every day, but once every few days to a week.

Why did goldfish die so fast?

1, feeding problem: choose to feed at noon. Goldfish in high temperature environment have the best appetite. Never feed them in the evening or at night, so goldfish are prone to stomach problems (symptoms are cotton patterns in the tank and pulled out by goldfish). Feed them once a day. 2, the problem of water: fish water must be placed in the sun for at least 5 days before use. If you want to raise fish well, you must form such a habit. You have to prepare a bucket full of water and put it in a sunny place. Wait until the fish water is dirty, then use the water in the bucket to raise fish, and then fill the bucket. 3. Summer is the favorite time for goldfish to get sick, not because goldfish are afraid of heat, but because the temperature is high, and there will be many germs and parasites in the water, so it is best to put food salt in the water, and it is best not to put edible salt, because edible salt contains iodine, and fish shops sell salt without iodine, which is what sellers often say. 4. It's still the problem of water: the conditions for raising fish may be different for everyone, and some people can buy big fish tanks. But some people can only raise fish in a small tank without other equipment, so the fish will be prone to lack of oxygen. If your fish tank is small, don't put too much water, or the fish will suffocate. It is recommended to put it below half a tank and pay attention to the density of fish. If the tank is small, don't raise too many, or you won't raise any fish. If you find that fish always float to the surface to breathe, it means that the fish is short of oxygen. This phenomenon is called floating head. When we find this situation, we should take measures as soon as possible. I didn't understand it before. Most of the raised fish died of lack of oxygen. It is also very important to change water for fish at night, not at noon. It is mentioned above that feeding should be at noon, and the temperature difference of water should not exceed 3 degrees when changing water. In fact, there is no need to get stuck like this. Feel it with your fingers. Although goldfish are not afraid of cold or heat, they are most afraid of sudden changes in temperature difference. When the water reaches dark green, it must be changed. All other colors can be changed. In addition, when changing the water for the fish, you should also be careful not to hurt the goldfish, not to tear the tail, and not to lose scales, which will not look good. Although they grow, some species do not grow well, such as fish with pearl scales. 6. It is best not to feed goldfish with live fish food sold on the street (sellers often call it line food or wet fish food). It is easy for beginners to master it badly. This kind of fish food tropical fish is ok, but goldfish is not. If you want to feed goldfish this kind of fish food, you must rinse it every time you feed it. This kind of fish food goes bad easily, especially in summer. And don't pour it into the fish tank at once. As long as the goldfish are fed with dried fish food, the fish can grow well. 7. Choosing fish at the beginning is the key to raising goldfish. Don't pick those unsociable fish. Such a fish is likely to get sick. You should look for them in the fish. When you pick them, you should touch them with your hands or with a fishing net. If you touch them, they will swim away immediately, which means the fish are healthy. If you meet them, there is no obvious performance, or you swim lazily. More than 90% shows that this fish has a disease. Never buy it, it will only live for two or three days. Don't mix fish with other fish immediately after buying them. If the goldfish gets sick, it will soon infect other fish, so the whole fish tank will be unlucky. It is best to put it in a basin or other container for a week. If you don't think the fish is serious, you can put it in a fish tank, and don't use the fish you bought and the water in the plastic bag. You should just take the goldfish out and put them in your own water. There are many fish in the water in the fish shop. Maybe one fish is sick. So most water has bacteria. Some people don't know that the fish is still alive and kicking when they buy it back, and they die in a few days. Mostly because of the water problem. Some books on fish farming say that the plastic bags of fish bought should be put in water until the fish adapt to the water temperature. Actually, there is no need to do that. Feel it with your fingers. Remember not to feed the newly bought fish. Don't be afraid that the fish will get hungry. It's not hungry at all. Goldfish are very hungry. Two months without feeding won't kill you. Once again, I may be blamed for nagging, but all the above are necessary for fish farmers. I have been raising fish for several years, but this is my valuable experience at the cost of the lives of several fish, which I won't tell most people.

Why did the goldfish just bought die soon after a few hours?

The causes of fish death are as follows. Please be symptomatic. Early prevention is very important. * * Prevention should be given priority to at ordinary times. After a large number of water changes, 1% large grain salt (or gentamicin) can be added to prevent fish diseases. Please don't copy, and respect the achievements of the original creator.

1. Hypoxia.

2. Poor water quality (turning white or green) will make fish sick.

3. You can't use tap water directly, but use water that has been trapped for at least three days to change water.

You can't change more than one third of the water at a time, and you can't change all the water. Fish that change all the water will not adapt to the new water and pile up and die.

5. The difference between the water temperature of changing water and the water temperature of the fish tank should not exceed two degrees, otherwise it will stimulate the fish.

6. Goldfish may be dead, but they don't know how hungry they are.

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

1. In addition to eating artificial compound bait, I prefer to eat red worms, line snakes, jumping insects and so on. To ensure that the bait is fresh, it can't be fed if it goes bad.

2. Feed it 1 time every day and regularly. Goldfish don't know if they are hungry. Feed them 80% at a time and eat them in five minutes. Fish can grow healthily and keep the water fresh for a long time. If you feel that feeding once is not enough, you can also feed it twice, but in the form of eating less and eating more meals, feed it for five minutes at a time and once in the morning and evening.

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 manure on time every day, and then add the same amount of trapping water to suck it out (it takes three days to trap to achieve better dechlorination effect), so you can keep the water clean and inject oxygen only by changing a little water. It takes more than a week to change water in large quantities (or if the water is mixed), that is, 3/ 1 water change is enough.

If there is no old water at home before buying fish, then use the water that has been trapped for seven days (that is, tap water in other utensils for more than seven days) to raise goldfish. Don't rush into the tank after buying it. Soak the plastic bag containing fish in the fish tank for ten to twenty minutes before opening it, so that the water in the tank can flow into the bag for many times and gradually mix with the original water in the bag, so that the fish can gradually adapt to the water temperature and quality.

Why do domestic goldfish die so easily?

Keep goldfish at home, and put the glass jar in a ventilated, sunny place near the window. Attention should be paid to stocking density and reasonable arrangement should be made according to the size of containers. It is better to raise more than less. Because the indoor air circulation is not good, raising more water is easy to be turbid, which can easily lead to goldfish dying of lack of oxygen. If you have a pump, you can raise more. If the goldfish is found to have a floating head, it is necessary to turn on the air pump for oxygenation, especially at night.

Live fish worms are the most ideal bait for family fish farming, and the water quality is not easy to deteriorate. Dried fish worms and synthetic pellet feed can also be used. There are live fish and worms on the market now, but it is also very troublesome to buy them every day. For dried fish worms sold in the market, choose fresh and loose particles to feed the fish, and don't buy old and moldy dried fish worms to feed them. It is best to use full-price feed with complete nutrients for artificial pellet feed, which is sold in the market.

In order to keep the water pure, the feeding amount should be strictly timed and quantified. Usually, it is advisable to feed 1 2 times a day, and each feeding amount should be eaten within half an hour. Don't feed too much bait. Feeding too much has two disadvantages: first, the fish is full, the metabolic level is improved, and the oxygen consumption is increased, which is easy to cause goldfish to die of hypoxia and suffocation; Second, the bait is left, which is easy to rot and ferment, making the water quality worse and causing hypoxia. In fact, goldfish are hungry, and there will be no problem if they are not fed for a week or two.

It is very important to keep goldfish clean. It is necessary to suck off the accumulated slag with latex tube regularly, clean up the feces and residual bait at the bottom of the glass jar together with turbid water, and then slowly replenish the fresh water that has been left for one day. If water plants are found floating or rockeries are knocked down during operation, they should be restored to their original state in time.

The longer the fish is raised, the more sediment will be deposited. Although it is removed every day, it cannot be completely removed. If the sediment increases and affects the clarity of the glass jar, it is necessary to completely change the water to clean the glass jar, so as to keep the water pure and easy to watch, and also to maintain a good living environment for goldfish.

Rectangular glass jars used by ordinary families are small in size, so it is not advisable to store more, and less should not be more. For example, in a container with a length of 40 cm, a width of 25 cm and a height of 30 cm, six to eight goldfish with a length of 5 cm to 7 cm can be raised. Adult fish with a body length of more than 8 cm should not be kept in small glass tanks, but in luxurious large glass tanks or ceramic tanks, and equipped with small oxygenators for standby to prevent hypoxia. The above stocking density is for reference only, but also depends on water temperature, fish size and water quality. This cannot be done mechanically. Generally speaking, if the fish is big, it is necessary to raise less; You can raise more in winter and less in summer; You can raise more when the water temperature is low, and raise less when the water temperature is high.

Choose goldfish

Choose fish with strong bodies and bright colors.

If you choose any kind of goldfish, you should choose the one with broad and firm body, complete chest, abdomen and caudal fin, and wide tail. Fish without dorsal fin should have a smooth back and no incomplete dorsal fin or nodule. The colors of fish should be red and delicate, white and pure white, blue and blue, black and dark, the colors of flowers should be harmonious and the patterns should be meticulous. Only those with blue can be called Wuhua. Some fish are half red and half black, or those whose bodies are red and the edges of their fins are black. They look beautiful at the moment, but in fact they will soon become all red, so be prescient.

When choosing fish, choose those that are unique in characteristics, body shape or color and observe them.

Choose healthy and disease-free fish.

Generally speaking, swimming in the pool (basin) is active, gregarious and plump. The pectoral fins and ventral fins are open and often paddle, and there are no white spots and white fluff-like mucus on the body. The tail and scales are congested and festered, and they do not often float on the water, nor do they lie on their side, stand upside down or sink to the bottom. Black and thick shit is healthy fish, and fish are looking for food.

Choose fish with obvious characteristics.

All kinds of fish have the characteristics of this species: such as longevity head, lion head, crane top red, goose head red and other species, which are famous for their sarcoma on their heads. Therefore, we should choose the most developed and widest sarcoma on the gill cover of their heads. In addition, fish with red sarcoma, such as crane top red and goose head red, are all top grades with square red tops (the top of the head is darker when young). When choosing pearl oyster fish, we should pay attention to two kinds: big tail and small tail, and the big tail is better. But no matter the big tail or the small tail, we should choose the small head with thick beads and scales, and arrange them neatly until the back, but the scales can't stand up, otherwise most of them are scales. Abdominal distension is thick and round with smooth tail. This feature is purebred. Blisters or dzi beads are named according to the characteristics of the eyes, so choose round and symmetrical blisters and soft and transparent blisters. Choose a person who has a big eye plate and protrudes like a chess piece. ...

How to raise goldfish so as not to die so easily?

Goldfish are actually very easy to raise. The following is a summary of my personal experience, please have a look. In the 1 feeding environment, you can choose fish tanks or fish ponds for feeding, but remember that goldfish are cold-water fish and have a great demand for oxygen. Adequate space and dissolved oxygen are the key to ensure the healthy growth of fish. 2 water quality, because goldfish can adapt to a wide range of water quality, the water quality in most parts of China is suitable for raising goldfish. For us ornamental fish lovers, "raising fish first raises water" is a wise saying. After raising water, raising fish will be handy. Goldfish like green water. If goldfish live in green water, they will grow much faster than clear water. If it is raised in green water, pay attention to "returning to clear water". 3 feeding, many people will ask, how many times a day? In fact, there is no standard answer to this kind of question. Don't feed them blindly, but change them according to different situations. Don't feed the fish you just bought, 1-2 days later. Most domestic goldfish are fed with feed, which is not as good as live bait, so we should often feed some fish worms, water worms and so on. Not only do fish like to eat, but it is also very helpful for fish coat color. It is best to soak the live bait in potassium permanganate and disinfect it, then wash it, and then you can feed the fish. Goldfish can be fed once or twice at a time. Don't overfeed them. Live bait can be fed more, and the fish will eat it at their own discretion and will not be full to death. Goldfish will die because they eat artificial feed and swell when they meet water. After the fish ate the feed, the feed swelled in the stomach, so the goldfish died. If you can't master the feeding amount, you can feed the feed equivalent to fish head 1/2, so that the fish won't be hungry and die easily. When you can master the feeding amount in the future, you can increase or decrease the feeding amount yourself. If fish are sick, feed should be reduced or suspended to avoid wasting or affecting water quality. How long does it take for goldfish to change water? Generally it depends on your own situation. If the water quality is turbid or the goldfish lacks oxygen, it should be replaced immediately. Generally, it is changed once every three or four days in summer, once in spring and autumn, and once every half month in winter. For fish farmers, there are four kinds of water: first, fresh water, that is, tap water that has just been aired or well water that has been newly pumped. Although this kind of water is clean, it is very different from the environment in which fish live in nature. Because there is no nitrifying bacteria community in the water, fish excreta and scattered food residues decompose into ammonia after corruption, and fish are easy to be poisoned. Second, the old water, light green or amber, is rich in humus and beneficial microorganisms and algae, and has established a good ecological circulation system. After nitrogen is recovered, it is decomposed into nitrate which is harmless to fish. This kind of water is extremely beneficial to the growth of fish. The third is green water. There are too many organic matters in the water, cyanobacteria, green algae and brown algae multiply in large numbers, and the content of bacteria and microorganisms increases sharply. The water is thick green, and sometimes it smells bad, which can easily lead to the death of the whole tank of fish. The fourth is to return to clear water, also called biting clear water. It is because there are too many algae and microorganisms in the green water, which consumes the oxygen in the aquarium, causing the death of algae and aerobic bacteria, and turning the water into stagnant water without oxygen and a large number of anaerobic harmful bacteria. It can be seen that not all water is suitable for goldfish's life, and the most suitable water for goldfish's growth is old water. Hydroponics is the process of changing new water into old water. At present, most of the water we use for fish farming is tap water, so the first step of water cultivation is to remove the toxic substance-chlorine from tap water. The method of chlorine removal is relatively simple. After the water is filled, let it stand for 2-3 days, or dry it 1 day (in case of urgent need, add 0.5% per 100 kg of water). 63g of baking soda, namely sodium thiosulfate, can be used immediately). After the fresh water is dried, it should be put into a tank for filtration, so that the water pump can turn the still water into flowing water, and then put the fish into the tank. "Broken tank" is to put a few cheap, strong and easy-to-raise fish into a new tank. After a few days, fish excrement will be decomposed into ammonia in water, which is the same as adding ammonia to tap water. Too much ammonia will kill fish, so the most important thing to raise water is to remove ammonia from the water. Generally, change the water once a week or so, and it can be longer in winter. Generally, it is enough to change 1/3 at a time. Change the whole cylinder water every 1-2 months. If the water quality suddenly deteriorates or becomes dirty, all water should be changed immediately, and the water change time should be adjusted according to the actual situation. When changing water, fresh water must be used, and the water temperature cannot be different from that of the original cylinder by 2 degrees. Use water that has been dried for 1 2 days, depending on the turbidity of the water. Leave 1/3 old water when changing water! ! Get rid of fish droppings and endless food every day (this is the heaviest ......

Why did my little goldfish die?

In fact, there is no trick to keeping goldfish. I can say frankly that I am not an expert in this field, but I must master some common sense of keeping goldfish.

The causes of death of goldfish can be roughly divided into the following categories:

1 died of overeating. This situation is usually due to the "doting" mentality of the owner, who is always afraid that his fish will be hungry. In fact, goldfish are very afraid of keeping. If it is a newborn goldfish, it only needs to be fed once every three days, a handful at a time. If it is a big goldfish, it needs to be fed once a day (this goldfish is usually two to three years old). ) can be properly debugged according to the specific situation.

Improper change of water leads to goldfish's death due to inadaptability to the environment. This situation is mostly caused by carelessness or fear of trouble. In summer, you should change the water once a week or so. If the weather is hot, change it several times, but not too much. Fish is an animal that depends on the environment. Water can be changed once in winter 10 day. Attention should be paid when changing water: if possible, prepare a small fish tank, and put the fish in the small fish tank when changing water (the water in the small fish tank must be filled for several days, and the small fish tank should be placed as close as possible to the big fish tank to keep the water temperature consistent, so that the fish will not feel the sudden change of the environment). The new water in the big fish tank can't be tap water just released, but it should be put in the big fish tank for a few days before use, otherwise the tap water will be too cold. After putting the water in the big fish tank, put the fish and water in the small fish tank together, which can reduce the goldfish from falling off too many scales when struggling.

Three people died of lack of equipment. Fish can't live without water, which is understandable, but the problem of oxygen is easily overlooked. I suggest you buy a set of equipment that integrates oxygenation and filtration. Remember to charge oxygen once a day, and the fish will float in the absence of oxygen. If you see it swimming in the upper layer of the fish tank, it proves that it is short of oxygen.

Besides, I suggest you buy a bigger fish tank. It is best to put two or four fish in a fish tank. I also suggest that you keep a small goldfish, preferably for more than a year or two. This kind of fish is easier to raise and less likely to die than small fish. Also, buy seaweed and put it in the fish tank. Fish generally don't eat seaweed. If you are afraid of being hungry and dare not feed more, put some seaweed to ensure that the fish will not overeat.
