Why do fish in glass tanks often die?

Breeding ornamental fish has a long tradition in our country, in ancient times, people generally used pots or small ceramic jars to raise ornamental fish. With the development of science and technology, if you breed ornamental fish at home, you will generally choose an aquarium to raise, which is what we call a glass fish tank. Why do fish die so often when fish are raised in glass tanks?

Your fish tank is a 30*20 fish tank, and the ornamental fish is goldfish, but it will die after a few days, how to deal with it? In terms of personal experience, although the container used for fish farming has a certain impact on the health of the fish, this is not the most important thing, the key is the method, the method is not right, no matter what you use to raise fish, the result is almost the same.

For a small fish tank like yours, if you want to raise the fish well, in addition to the problem of the fish itself, the most important thing is to raise the water, the problem of the fish itself can only be when we buy fish, try to choose those fish that are more active in a group of fish and some of the more easy to raise varieties back to breed, take goldfish as an example, you can choose grass goldfish, Liujin, and gold, these relatively more durable species, so that the probability of feeding it will be much greater.

And the most important point is the water quality, no matter what kind of fish we have to raise water before raising fish, that is to say, a few days before the plan to raise fish, add water to the fish tank and raise a few days (at least more than 3 days) of water and then put the fish into the raising, the purpose is to remove the chlorine in the tap water and raise some microorganisms at the same time, especially the fish tank with a filtration system must be filtered in the probiotic group to be stable before the fish can be released, or the fish is easy to have problems after the water quality changes. If you use tap water to raise fish, the water you usually change must be placed in an empty container 24 hours in advance to aerate, or the chlorine in the water is easy to make the fish poison and die.

The last point is to feed, just come back fish do not feed, at least let it hungry for more than 3 days before feeding, so that the fish is better, especially if you feed the fish in a small fish tank, it is very easy to spoil the water and cause problems with the fish. My personal advice is that if you are a beginner in fish farming, you would rather feed less and let the fish be hungry than overfeed, otherwise the fish will not last long.

Of course, fish farming is inseparable from oxygen, if there is no special aeration pump, the density of raising should be lower, otherwise it is easy to die of hypoxia, fish tank with filtration and aeration pump, normally 1 kilogram of water can raise a centimeter length of fish, in other words, if the total water volume of your fish tank is 50 kg, it is at most to raise 5 fish of about 10 cm (some of the more delicate varieties of density will also be reduced), if you are a novice or the fish tank is not filtered, the density of raising is lower, or it is easy to have problems.

One is because oxygen is not delivered to the fish tank, the second is because there is no regular feeding, and the third is because the fish tank is not changed frequently to keep it clean; Failure to do any of the above steps in fish farming can lead to fish death.

If you want to raise ornamental fish that are not easy to die, fish farmers should be familiar with the familiarity of the fish they raise, and try to provide the corresponding environment. Such as pH, temperature, water quality, oxygen supply, density, etc., usually observe the changes in the fish, find problems, and deal with them with corresponding methods such as healing, isolation, sterilization and disinfection, and reproduction). In this way, it is basically difficult to kill the fish, as shown in the picture, these fish are generally 20 cm into an adult, and now they have exceeded their length.

Fish is an auspicious symbol in our country, and people usually use it every year to express their yearning for a better life in the coming year. Business people will raise a few koi fish to attract wealth, some people will also raise some goldfish at home, rabbits have raised small goldfish, but within a week, the little goldfish are all dead.

The density is too large, or because the fish tank is too small, the contact surface between the water surface and the air is too small, the oxygen exchange is not enough, and the fish die due to lack of oxygen.

Because if the fish are raised in the glass tank without oxygen, the fish will not be able to be raised, so they will often die. And the capacity of the glass cylinder must be large enough.

Because the fish itself is in the sea, he doesn't like the environment of this glass tank, he can't adapt to it, so he is particularly prone to death.

Glued with glass, the fish absorbs into the glass glue.

Because we only use glass cylinders.

It may also be that the fish you bought is sick and then infected to the entire fish tank, so you should re-disinfect the fish tank now. Here's my basic experience of fish farming. 1. Fill the fish tank with water before entering the fish and leave it for 2 to 3 days.

2. The size of the fish tank determines the number of fish, do not raise it full for your own personal reasons, it is not good for the fish and it is tiring to clean up. The fish tank needs to be cleaned before putting the fish in. Use potassium permanganate or use coarse salt.

After soaking gentamicin for a period of time, rinse with water before use. 3. Tap water cannot be used directly and needs to be left for about a day. 4. After buying new fish, it is best to keep them alone for 3 or 4 days to observe whether there is any disease, so as not to infect other fish.

5. New fish need to be well watered before entering the tank. Place the plastic bag (don't put it if it's not clean) in the fish tank for about half an hour, when the temperature inside and outside is about the same, pour out half of the water in the bag, put some water in the tank, and pour the fish into the tank after repeating twice. 6. Don't feed people three times a day.

Once in the morning and once in the evening, you can feed a little at a time, and the fish can be eaten within 5 minutes. Dry feed should be fed sparingly. 7. Change the water, the water is said above, the water can not be changed completely, because the fish adapt to the water in the tank, if all are replaced, the fish may not adapt to the death of the fish.

Changing the water for 1 4 to 1 3 will do. 8. The temperature can be kept around 22 24, and some fish can adapt to lower temperatures. When the temperature is low, the fish's eating activity will be reduced.

9. To clean up the fish, you can buy a filter or use a pipe to clean it by siphon method. 10. Equipment, heating rod (used when it is cold), filter (used to clean fish BB), oxygen pump (used when there are many fish or high oxygen fish) The above I have sent in the question, and I have also sent it in fish3000, completely my own experience, non-**.

Many novices have summed up an experience in the process of fish farming, changing the water once every three days and changing a batch of fish every seven days, which is also the difficulty encountered by many novices in fish farming. When we spent an expensive price. We worked hard to put the fish at home and put them in a glass tank, but we didn't expect them to die in a few days, but we saw that they were very lively before we bought the fish, but they quickly left us after a while.

Some people can't help but wonder why fish often die when they are raised in glass tanks.

In fact, fish farming in glass tanks is not the key factor that makes the fish die, the important factor is that we do not see the diseases carried by the fish bought from outside. Some fish sellers know what diseases are in the fish, and they will strongly recommend this fish to you, because you don't know that the fish disease will be easy to detect from the **. So you quickly became a fish seller, and every two days after we bought the fish, the fish quickly died, mostly because of the diseases carried by the fish themselves.

Another factor is that when we raise fish, the water is not so strict, and it is directly connected to the tap water, which is also harmful to the fish. Because fish often live in the sea, there are many elements in the sea, and there are not so many elements in tap water, which can also cause fish to die due to malnutrition. Another factor is that many people like to buy several fish and put them in one tank, which will increase the fight between fish and predation.

There are some different species of fish that will attack each other and cause more and more fish in the tank to die, if we find that the fish are fighting with each other, we should separate the fish in time, so as to avoid the death of the fish.

The water we raise fish should be exposed to the sun for a few days so that the chlorine in the water can be removed and the fish can survive better. If we use FRP to change the water for the fish, try to save some of the original water, so that after changing the new water, the fish can also be better adapted.

It may be that there is not enough oxygen in the water, it may be that the state of the fish is not paid attention to regularly, it may be that it is infected with bacteria, or it may be a lack of nutrients.

Because fish also need oxygen, the density of the glass tank is too large, or the fish tank is too small, the fish will die of lack of oxygen.

Because the water used is different, some fish are suitable for raw water, and some fish are suitable for salt water.

With the improvement of people's quality of life, more and more people like to have pets at home, and goldfish have become the first choice for most people to have pets because of their small size. How to raise fish well in glass tanks? Next, I will explain to you in the morning, I hope it will be helpful to you.

1. Water quality problems Fish farmers forget that the tap water is the result of the waterworks filtered and purified and disinfected, and after purification, the tap water often contains chlorine residues, which are the natural enemies of the fish. Therefore, it is best to use natural water, well water, or tap water to dechlorinate the tap water before raising fish.

2. Hypoxia problem Because the volume and capacity of glass tanks are relatively small, and many people like to raise more fish, these fish tanks, especially in the case of hot and humid weather, are easy to cause hypoxia, and once the water is hypoxic, it is easy to cause fish death. Therefore, fish farmers must be equipped with aeration equipment.

3. Water pollution Feeding too much feed, too much fish excrement, will cause water pollution, some people are afraid that the fish are hungry, a large number of feed, resulting in fish can not eat, too much feed will pollute the water body, the same does not remove the fish excrement, aggravate the degree of water pollution, once the pollution is too much, fish.

The reasons for the old and dead fish in the fish tank: the tank is not opened, the water is not raised, the feed is not good, and the fish have problems.

1. If the tank is not opened: if it is a freshly glued fish tank, it needs to be placed in a ventilated place, after the smell disappears, add water to it, add a little potassium permanganate at the same time, soak for 3-4 hours, put the water away, and rinse it several times, so that the disinfection is completed.

2. Not raising good water: Usually the water for raising fish at home is the tap water of Piqin Spring, the water has residual chlorine, and it needs to be dried for a few days until the chlorine volatilizes.

3. Poor feed: The growth of fish is inseparable from nutrition, so it is particularly important to choose the right feed, and don't give too much, usually only need to feed once or twice a day, don't feed too much each time. If there is any food residue in the water, it must be cleaned up immediately.

4. There is a problem with the fish: if the quality of the fish itself is not good, no matter how much it is raised, it will not live long, so it is also very important to choose a good fish, buy fish in a regular store, do not buy it online, because long-distance transportation can also cause fish death.

Different water quality cannot be polycultured

This is a common mistake made by novices, which is to buy a fish they like and buy it at home, without thinking about whether the fish will get along with your fish and whether it will adapt to the same environment. Shouming.

In this case, there are two situations that will occur, one is that the law of the jungle will eat the fish that you bought back and the fish you raised before. The other is that the adaptation is different, and the fish that do not adapt will die. When buying fish, you should first understand whether you can polyculture with the fish at home before making a decision.

The reasons for the successive deaths of the fish in the fish tank: the tank is not opened well, the water is not raised well, the feed is not good, the fish have problems, and there is a serious lack of oxygen.

1. If the tank is just sticky, it needs to be placed in a ventilated place, emitting the smell, after the smell disappears, you can add water to it, and add a little potassium permanganate at the same time, soak for 3-4 hours, put the water away, and rinse it several times, so as to complete the disinfection.

2. Not raising water well: In addition to opening the tank, raising water is also an important step, and fish can only be raised when the water is good. Usually, the water used to raise fish in Jiatong Bend is tap water, which will not be polluted, but there is residual chlorine, which is very dangerous for fish, so please dry it for a few days until the chlorine volatilizes.

When water is first raised, nitrifying bacteria are added to establish a nitrification system.

3. Feed is not good: the growth of fish is inseparable from nutrition, so it is particularly important to choose the right feed, in addition, do not give too much, otherwise the fish will get enteritis, usually only need to feed once or twice a day, do not feed too full each time, always keep the appetite constant, if there is still food residue in the water, it must be cleaned up immediately.

4. There is a problem with the fish: if the quality of the fish itself is not good, no matter how much you raise it, it will not live long, so it is also very important to choose a good fish, buy fish in a regular store, do not buy it online, because long-distance transportation may also lead to the death of fish.

5. Severe hypoxia: If the fish tank is seriously hypoxic, the fish will also die, the reason why such a thing happens is because the feeding density is too high, the oxygen consumption is too high, and there is no oxygenation equipment in the tank, so it is necessary to install an oxygen pump at this time, and oxygenate the tank in the whole game to avoid hypoxia.
