Choosing water for the aquarium

There is no absolutely pure water in the world, it is mined in laboratories using step-by-step distillation. Water from a water supply system or natural source always contains impurities of various substances that play an important role in the ecosystem. Considering that many modern people keep fish at home, everyone wants to use the highest quality water for them. But what should be the water so that it can fill the home aquarium?

What you need to know about spring water

For a long time it was believed that spring water, recruited from a crystal clear stream, is best suited for ornamental freshwater fish. Perfectly clean, transparent, odorless and dirt free - that's exactly the kind of tank you can fill! It turned out that typing this is not always safe. Its difference from tap water is high rigidity. Even the soap in it is difficult to dissolve, what can we say about fish food. Due to the high content of magnesium and calcium salts, it has a detrimental effect on the health of the fish and their offspring (eggs). Unfortunately, the water from the spring is not recommended to add to an artificial aquarium. Occasionally it is mixed with water to increase rigidity.


Distilled and rainwater

Since the springs have increased hardness, can it be better to pour soft water into the tank - rainwater or distilled water? Again, not always - just mixing it with the plumbing. There are fish that love the environment with softened water, but many freshwater species still prefer medium, neutral water. Such water flows in domestic rivers and lakes - you can pour it purified into the aquarium, filling it with not all the space.

Watch the video on how to change the water in the aquarium.

What habitat most love aquarium fish

What water is needed for an aquarium? Combining water from different sources, it is impossible to achieve the ideal parameters. How many fish, so many requests. Some fish can live in the melt water of mountain lakes, others - in the brown marsh. In the first case, the water is very hard, in the second - soft. Fish have to settle in a different environment. It turns out that some fish are orderlies who love rotten water, others do not tolerate such parameters. Rotten environment is detrimental due to humic acids. Many freshwater biotopes of our country have pH neutral water, medium acidity, low alkalinity. For most aquarium fish, it is suitable.


Aquarium water for unpretentious fish

Water that must be prepared for not very capricious ornamental fish requires preliminary preparation. In the general aquarium it is necessary to fill in soft (sometimes medium hard) pH-neutral water. This can be plain tap water. In it, live-off and viviparous fish, which perfectly adapt to different conditions, take root well.

See how to change the water and care for the aquarium.

The degree of hardness can be measured using litmus paper, the temperature of the water - with a thermometer. Water of high degree of hardness is recommended to be mixed with soft rainwater (filtered) or distilled. Also, water from clean, melting snow or ice. The listed types of water can be collected in a clean container only after prolonged precipitation; it is enough to pour 30% soft water into infused water from the tap.

Water from the tap can not be poured immediately. It is better to pour it into a glass, and see if the glass is covered with bubbles, whether a strong smell will emanate. Such water is saturated with compounds of gases that fell into it during filtration at the treatment plant. Having let the fish in such a liquid, the pet's body will instantly become covered with bubbles, which will penetrate into the gills and internal organs. As a result, the fish will die. In addition to gas, chlorine is added to water for disinfection, it will also poison living beings.

To get rid of gases, tap water can be poured into glass containers, and let it settle there for several days (2-3 days). There is another quick way: pour water into enameled ware, bring it to the stove to 60 or 80 degrees, set aside and cool. Boiled water is harmful - it leaves on the walls of dishes scale calcium carbonate and magnesium. Boiled water can be poured into spawning, but in extreme cases. To fill the entire area of ​​the aquarium with boiled water will take a long time. Another nuance - boiled water kills all the useful microflora.


If you do not have water supply (this occurs in our time), you should go to a clean river or lake (where there are no signs "No swimming is prohibited!", Etc.), and take water from there. If it is clean, river fishes (perch, bream, roach) really live and flourish in it, there is a water grid plant, which is a good sign. To destroy parasites, such water is heated in an enamel pot to 80-90 degrees, but not to make boiled water out of it. The parameters it will be different from the liquid from the tap, so think about whether to take such a risk. You can go to another house, and get running water there.

In addition to thawed, spring, rain and distilled water, it is advisable to pour 30% of the water from the old aquarium to the infused liquid from the tap. If he was kept safely, the fish and plants did not hurt there, the water in him was not muddy - this is a find. In the old (residential) aquarium water, whether it has been poured from a tap for a long time, there are many useful microbacteria that will create in the new dwelling the natural biological environment. In a residential aquarium environment contains a number of organic impurities that are very useful for the aquatic environment. They make the water more acidic, do not allow the putrefactive and pathogenic bacteria to multiply. If high-quality and proven water is poured into the tank, all its inhabitants can be healthy.

What kind of water to fill in the aquarium?

Many people who decide to start an aquarium want to know all the details about keeping fish, choosing plants and caring for water. But the first dilemma faced by an inexperienced aquarist is how much water should be poured into the aquarium? There are a number of requirements for water quality and several ways to clean it, which will help to achieve the desired consistency.

What water should be poured into the aquarium?

For the aquarium should be selected soft neutral water. In large metropolitan areas such water flows in the aqueducts. In places where the water supply is connected to artesian wells, the water turns out to be too hard. It is suitable only for viviparous fish, adapted to all sorts of adversity.

Too hard aquarium water can be softened by mixing it with soft distilled or rainwater. Water from melting snow / ice is also suitable. And collect rainwater and ice after continuous, long-term precipitation. To replace the water in the aquarium, you can mix 1/4 of rainwater.

If you decide to use tap water, then follow these guidelines:

  1. Do not pour water from the tap. Pour it into the jar, you can see that its walls will be covered with bubbles. These are gases. They got into the liquid when it was passed through cleaning filters. Having put a small fish in such water, you risk that its body and gills will be covered with bubbles, and ulcers will form on the affected areas.
  2. Ensure that the water is free of chlorine.. If the water contains more than 0.1 milligrams of chlorine, the young fish and larvae will die in a couple of hours. A concentration of 0.05 milligrams of water will kill fish eggs.
  3. Monitor pH. Changes in the pH level are often observed in an artificial pond with soft water and low carbonate content, with strong sunlight. To remove the free acid, you need to blow the water column with air and deliver the water to the aquarium in batches, and the pH should not be less than 7.

If you follow these indicators of water in the aquarium, then it will not be green for a long time, and the fish and plants will fully develop.

Aquarium water purification

Little just prepare the water and pour it into the aquarium. Her follow-up care is required. which involves filtering and ozonation. The most common filter types are:

  1. Internal. The most budget, and therefore a common option. It is a pump that distills the liquid through a foam sponge filtering composition.
  2. External. They are often bought for large volumes. They do not take up extra space inside the aquarium and have large volumes of filter materials. Sterilizers are also installed on the external filter.

As you can see, collecting water for the aquarium and its further control is a simple process.

Film on the water in the aquarium - what to do?

Owners of aquariums often notice some unpleasant moments concerning such "water houses". As you know, in order for small fish, snails and other living creatures not to suffer from various diseases and live as long as possible, it is necessary to provide them with full-fledged conditions. The film on the surface of the water - not uncommon. Many owners of aquariums can not understand why it was formed and what it means. Well, and accordingly, the most important question: what is the risk of such a phenomenon?

Water surface film causes

The film found on the water often causes the owners of aquariums to suffer with questions: what is it and how can it harm the fish? In fact, such a phenomenon is most often the result of improper care of the aquarium. The main reasons for the appearance of films on water:

  • pollution of aquariums;
  • ingress of foreign particles into the water;
  • the presence of rotting products in an aquarium;
  • reproduction of bacteria.

Accordingly, any negative processes related to aquarium water are accompanied by the presence of a large number of pathogens. If the presence of a film is detected in an aquarium, this always involves the reproduction of bacteria. They are known to have negative properties and can very seriously harm floating fish and snails, which are very sensitive to bacteria.

In order to avoid troubles associated with the pollution of aquarium waters, you should constantly monitor the cleanliness in the aquarium. It is necessary to regularly clean the water in large tanks, and in small ones to replace it with fresh water. This will prevent such troubles and will be able to prevent diseases of the fish. It is important to properly clean the water and ensure that it does not appear any traces of reproduction of microorganisms that can harm animals and fish living in aquariums.

What is dangerous film on the surface of the water in the aquarium?

Since the appearance of the film in the aquarium water is always an alarming bell, it is therefore important to notice such changes in time and take action. If nothing is done, then the following troubles are possible:

  • the growth of bacterial colonies;
  • diseases of aquarium inhabitants;
  • death of fish and other organisms living in aquariums;
  • oxygen starvation.

In a polluted environment, harmful microorganisms feel particularly comfortable and begin to actively proliferate. They poison their environment with waste products and lead to the fact that the fish have nothing to breathe, as well as fish affect various diseases.

To avoid serious problems, it is important to ensure that no film appears on the surface of the aquarium. It is important to note that it is the insufficient amount of oxygen that leads to the reproduction of malicious microbes.

The film on the surface of the aquarium. What to do?

As you know, any trouble is easier to prevent than to try to get rid of it. At the same time, the appearance of such a problem does not mean hopelessness. If, nevertheless, aquariums are distinguished by the presence of unfavorable films, you should immediately begin to act, until the pathogens have spread at a furious rate throughout the aquarium element.

Since the aquarium films have a bacterial nature, it should fight with bacteria. It is necessary to create conditions under which infections can not multiply and poison the fish. The easiest way to solve this problem: use a napkin, dry. It should be placed on the surface of the aquarium water, be sure to respect the accuracy. Then it will also need to be carefully removed. In this case, all the bacteria along with the film will be on a napkin, and the water will be cleared of such rubbish. But a single use of a napkin will not be enough. Dry wipes should be applied no less than four times. This is the only way to purify water.

After the film surface on the water is removed, a siphon must be used. It will clear the bottom of all bacterial debris and allow the waters to actually become clean. Replacement of water is also necessary. If it is a large aquarium in which not less than seventy liters of water, in this case it is necessary to replace about twenty-five percent of the entire body of water.

After the water spaces are cleared, it will be possible to proceed to the next stage of the struggle - to use the aerator and filter. This will help to fully cope with the existing problem and there will be no trace of it. But so that in the future a film does not appear on the water surface, it is advisable to observe the following rules:

  • unfinished fish feed must be extracted without preventing their decomposition;
  • it is better to feed the fish of the dry type infrequently, as they contain substances that provoke the appearance of films;
  • Before you put your hand in the aquarium, you need to wash it thoroughly with soap and water;
  • in order to avoid dusting of the water space, it is necessary to cover the aquarium with a lid;
  • the water that will be used to replace the old one must be separated (up to three days).

This way you can track the occurrence of blockages in the aquarium. And it is extremely important to do everything necessary to prevent the development and reproduction of pathogenic microbes. Since they are very harmful to the health of small fish and snails, they must be immediately eliminated if they are found.

Why do fish in aquarium suddenly start dying?

Unfortunately, like other living creatures, fish can die ahead of time. Why it happens? The answer to this question is often sought by novice aquarists. It is much more effective to prevent the appearance of such a problem than to look for the causes of a pet's death.

Ideal if you asked this question before the moment the tragedy occurred. Warned, so ready to control all the nuances of the aquarium and try to avoid the early death of aquarium inhabitants. Consider the most common reasons.

Nitrogen poisoning

Nitrogen poisoning is the most common problem. It often concerns beginners who have no experience in dealing with aquarium animals. The fact is that they are trying to feed their pets to the dump, forgetting that with this increases the amount of waste. By the simplest calculations, each fish per day leaves feces equal to 1/3 of its weight. However, not everyone knows that in the process of oxidation and decomposition nitrogen compounds appear, consisting of:

  • Ammonium;
  • Nitrate;
  • Nitrite.

All these substances are united by their toxicity. The most dangerous of them is ammonium, the excess of which will be the main cause of death for all inhabitants of the reservoir. This happens most often in newly launched aquariums. The first week after the start becomes critical. There are two options for increasing the amount of these substances in aqua:

  • Increase in the number of inhabitants;
  • Breakage of the filter;
  • Excessive feed.

It is possible to determine the surplus by the state of water, more precisely by smell and color. If you noted the darkening of the water and the smell of rot, then the process of increasing ammonium in the water is started. It happens that when visually inspected, the water is crystal clear in the house for fish, but the smell makes you wonder. To confirm your suspicions, ask special chemical tests at pet stores. With their help, you can easily measure the level of ammonium. True, it is worth noting the high cost of tests, but for a novice aquarist they are very necessary if you do not want to lose all your pets for a couple of days. If time corrects the situation, then the death will be avoided.

How to lower the level of ammonia:

  • Daily water change ¼
  • Water should stand at least a day;
  • Check the filter and filter element for serviceability.

Wrong launch of fish

Imagine what a fish is experiencing when it goes from one water to another, the parameters of which are significantly different. Buying a fish in a pet store, you deprive it of its usual environment, transferring it to your own, which is completely unfamiliar to the fish. Water differs in hardness, temperature, acidity, etc. Of course, the reaction to such a change will be stress. A sharp change in acidity of at least 1 unit indicates death for sensitive fish. Sometimes the difference in acidity is much more, so the shock that the fish is experiencing can end in death.

Proper adaptation of the fish to the new environment:

  • Pour the water with the fish in a large vessel;
  • Top up some water from the common aquarium;
  • After 10-15 minutes, repeat the procedure;
  • Dilute with water to at least 70% solution.

Even if several new fish managed to survive after a crushing change of water parameters, then they will surely die in the first illness. Immunity is significantly undermined, which means that bacteria attack them first. Carefully follow the aeration, cleanliness and new inhabitants. At best, the health of the fish is normalized.

Fish diseases

No one wants to blame himself, so beginner breeders blame the disease.Unscrupulous sellers only reinforce their doubts, because they have a goal to sell expensive medicine and cash in on. However, do not rush for a panacea, carefully examine all possible causes of death.

Blame the disease is possible only if the symptoms have been noted for a long time. The fish died away gradually, and not just died in an instant, for no apparent reason. Most often, the disease is brought to the aquarium with new residents or plants. Death may occur due to malfunction of the heating element in cold weather.

Going to pet stores, you should be aware of what exactly you need medicine. Each of the drugs directed to a specific disease. Universal drugs do not exist! If possible, consult an experienced aquarist or ask a question on the forum, knowledgeable people will tell you what to do in this situation.

Of course, the disease can not kill a healthy fish. Why die fish in an aquarium? If the death occurred, then the immunity has already been undermined. Most likely, the first two errors occurred. Do not rush to launch new residents, no matter how beautiful they are.

What to do to protect the aquarium:

  • Organize quarantine for new inhabitants;
  • Sanitize fish or plants.

What to do if the disease started up in the aquarium:

  • Change one tenth of the water daily;
  • Increase the temperature;
  • Strengthen aeration;
  • Remove the carriers of the disease and those who are clearly infected.

Remember which fish you ran at home last. Individuals brought from other countries can be carriers of rare diseases, and it is sometimes impossible to detect and classify on their own.

Water quality

Utilities do not set themselves the task of purifying water to such an extent that aquarium residents feel comfortable. Their goal is to make it safe for the person and his home. Hence the popularity of bottled water. Tap water contains the maximum chlorine level. In large cities, there may be a probability of changing water from artesian to desalinated. As a result, water hardness will increase, leading to mass death. You can notice this by the modified behavior of the fish - they begin to rush around the aquarium in a state of horror.

You can avoid this situation. For this:

  • It is not recommended to change at a time more than 1/3 of water
  • Settle the water in an open vessel for at least a day;
  • If possible, purchase a water filter with three secretions;
  • Use chemicals.

Please note that deaths are those fish that were already in a state of stress.

O2 deficiency

This option is the rarest of all. Oxygenation of a fish house is always adequately assessed even by beginners. The first thing they do is buy a compressor. With him, not terrible choking fish.

The only possible option is to increase the temperature and, as a result, lower oxygen in the water. This can happen at night, when the plants are rearranged from the production of oxygen, to its absorption. To avoid this, do not turn off the compressor at night.

Aggressive neighbors

Before you go to the store for pets, think over to the smallest detail, can there be several species in one fish house? You should not rely on the competence of the seller, since the main goal for him is to realize as much of the goods as possible.

A few fundamental rules:

  • Big fish always tend to eat small ones (even in the case of herbivorous species);
  • Many succumb to intraspecific aggression;
  • Some are able to stick to small neighbors, which ultimately leads to death;
  • The strong always eat the weak;
  • Buy only those fish whose peace-loving nature you are sure of.

Unfortunately, it is impossible to establish why fish die. The death of a pet can happen even to experienced breeders. Be attentive to the fish, and you will definitely notice a change in behavior and in time eliminate the cause of anxiety. More often, fish die in an aquarium because of an oversight, and not according to other criteria.

Fish die in the aquarium: reasons

Why die fish in an aquarium?

Sometimes in the aquarium, the fish begin to die one by one. Their owner makes a rash decision - he goes to the pet store and buys any funds offered by the seller. But nothing helps. So, why fish die in an aquarium? There are several reasons for this.

Bacteria - fight!

The main problem of all troubles in an aquarium is dirty water. Beginning breeders, as a rule, forget that the fish not only breathes and eats, but also feces. As a result, the increased content of nitrate, ammonium and nitrite leads to a mora. And the first two are especially dangerous. Poisoning with these substances can be seen with the naked eye: there is a smell of rot, the water becomes cloudy and the question: "Why do the fish die in the aquarium?" can be considered closed.


Bacteria that fight poison and toxins live in the filter media and in the soil. It is important to clean both substrates carefully but carefully. Otherwise, you can destroy the fighters for health. Thus, there is no need to clean the aquarium to sterility and periodically turn off the filter (otherwise anaerobic microorganisms will settle there). By following these simple rules, you can maintain the health of this biosystem and then the fish will not die.
To restore the lost balance, the following instructions are recommended:

  1. Stop feeding for a short period of time. Fish without food can last for several days
  2. Measure the level of toxic substances using special tests (sold at the pet store)
  3. If the readings are equal to 2 ppm, then it is necessary to replace half the water in the aquarium, but gradually, otherwise the death of the fish will not stop.
  4. Follow the second and third points for several days until the microflora is restored.
  5. In no case can not use antibiotics. They are completely destroyed biobalance!

It is important to remember that the aquarium, as a fabulous teremok, can fall apart if it is overpopulated. Fish die because of gluttony. If overfeeding occurs, food debris will simply begin to decompose. Therefore, it is better to reduce portions than to increase.

Acclimatization

As a rule, the temperature, pH and hardness of the water in the pet store is very different from the aquarium breeder. The strongest stress, and therefore the reason why the fish die in the aquarium, can become an ordinary room in a new habitat. Changes in pH can even kill pets or lead to their fatal illness. How to help them endure stress?
First you need to put the bag with the newly purchased fish in the aquarium and attach it with a clothespin to the glass. Then - weak aeration. After 10 minutes you need to pour into the package aquarium water. Repeat this step every 12-15 minutes. After half an hour, you can release the fish in a new home. And finally, the last step - the addition of anti-stress drugs and feeding.

Living water or dead?


If the fish die after the change of water and, moreover on a massive scale, it means that the plumbing companies are to blame. They are usually interested in the health of a person, not his pets. Companies may suddenly change the Ph or the hardness of the water. In addition, it is strongly influenced by the melting of snow.
In this case, it is recommended (especially in spring) to defend water, at least a day. In addition, it is desirable to heat it to 70 degrees, and then gradually cool. Another tip: do not make large changes of liquid (more than 30% of the volume). It is also important to avoid sudden changes in temperature in the aquarium.

Disease

Very often, this is the reason newcomers hear from sellers to the question: "Why do I have fish die in an aquarium?", Because the latter are interested in profits from sales of expensive drugs. It is important after the purchase of pets to quarantine, and sometimes - preventive treatment. But even in this case, the fish can get sick. In this case, to prevent the pestilence, the ill person should be placed in a separate aquarium.
Imported fish sometimes bring rare species of disease that cannot be determined without special laboratory analysis. In pet stores there are a lot of drugs that can save pets from misfortune, but it’s better not to be consulted about the choice of treatment from the sellers, but from experienced aquarists. But, as a rule, before treating the problem itself, it is necessary to look for its source: reduced immunity and, consequently, the poor state of the composition of the water.
Fish die from many causes, but the pillars of care for them are unchanged: regular cleaning of the soil and water filtration, timely replacement of water, not overfeeding.

What to do if you find a dead fish?

Suddenly discovered that you have died in a fish tank and do not know what to do now? We have compiled five tips for you to cope with the death of the fish and what to do if this happened. But, remember that even in the most ideal conditions, they still die. Often, suddenly, for no apparent reason and very annoying for the owner. Especially if it is a large and beautiful fish, such as cichlids.

Attention! First of all, check how your fish breathe!

Often aquarium fish die due to the fact that the water parameters have changed. The most pernicious effect on them is the low oxygen content of the water. Characteristic behavior is that most fish stand in the surface of the water and swallow air from it. If the situation is not corrected, then after a while they begin to die. At the same time, such situations can occur even among experienced aquarists! The oxygen content in water depends on the temperature of the water (the higher it is, the less oxygen is dissolved), the chemical composition of the water, the bacterial film on the surface of the water, the outbreak of algae or ciliates. You can help partial water changes by turning on aeration or directing the flow from the filter close to the surface of the water. The fact is that during gas exchange, it is the fluctuations of the water surface that play the decisive role.

1. Look at

Check and recalculate your fish daily, while feeding. Are they all alive? Are everyone healthy? Does everyone have a good appetite? Six neons and three speckled, everything is in place?
If someone is missed, check the corners of the aquarium and lift the lid, maybe it is somewhere upstairs in the plants? But you can not find a fish, it is quite possible that she died. In this case, stop searching. As a rule, a dead fish becomes visible anyway, it either floats to the surface, or lies on the bottom, the floor is snagged, stoned, or even falls into the filter. Every day, inspect the aquarium, did the dead fish appear? If found, then ...

2. Remove the dead fish

Any dead fish, as well as large snails (such as ampoules or mariz) should be removed from the aquarium. They rot very quickly in warm water and create soil for the development of bacteria, the water is muddier and begins to stink. This all poisons other fish and leads to their death.

3. Look at the dead fish

If the fish is not too decomposed, do not hesitate to examine it. This is unpleasant, but necessary. Are her fins and scales full? Maybe her neighbors beat her to death? Are the eyes in place and are they dull? Strongly swollen belly like in the picture? Maybe she has an internal infection or she has poisoned herself with something.

4. Check water

Every time you find a dead fish in your tank, you need to check the quality of the water with the help of tests. Very often the cause of fish death is the increase in the content of harmful substances in the water - ammonia and nitrates. To test them, get in advance tests for water, better drip.

5. Analyze

The test results will show two results, either everything is fine in your tank and you should look for the cause in another one, or the water is already rather polluted and you need to replace it. But, remember that it is better to change no more than 20-25% of the volume of the aquarium, so as not to change the maintenance conditions of the fish too dramatically.
If the water is all right, then you need to try to determine the cause of death of the fish. Of the most common: disease, hunger, overfeeding (especially dry food and bloodworms), long stress due to improper housing conditions, age, the attack of other fish. And a very frequent reason - and who knows why ... Believe me, any aquarist, even the one who has been keeping a complex fish for many years, has sudden deaths to watch his favorite fish.
If the incident is a single case, then do not worry - just watch out for new fish or die. If this happens all the time, then obviously something is wrong. Be sure to contact an experienced aquarist, it's easy to find now, since there are forums and the Internet.

Why die fish in an aquarium, what to do?


Why do fish die
or the story of the sad fate of goldfish!

The motive for writing this article was the communication on the form Fanfishka.ru with a certain citizen who wrote in the section on helping to determine the disease of fish.

"Help, please, I have a telescope at the age of 6 months. I haven’t eaten anything for three days. It floats on the surface with difficulty, there is enough air. There is no external damage and no swelling. Help if you can still, it’s a pity to lose fish."

Being a conscientious and sensitive person, I gave her a plan of action and events according to the full scheme, advised the preparations. And then, when I wrote everything, I thought - why should I treat it so radically, maybe the reason for the poor health of the fish lies on the surface? :)

In this connection, I asked a citizen: "Tell me, what is your aquarium volume, who lives there besides the telescope, etc."

When I received the answer, I just went nuts! I’m trying to get along with treatment and help, but it turns out that ... read the answer: "Aquarium 80 liters. 1 gourami, 2 thorns, 2 gold, 2 telescopes (1 patient, another healthy, but for some reason does not grow), 2 danios, 2 small antsistrus, 2 speckled catfish, 1 angelfish, 2 ampoules ... ".

The reason that the telescope was bad - was revealed !!!

Imagine if 16 people planted in an eight-meter hut, how much would they stretch? ... Whatever the conditions in this hut, the sea would start a month later.

Vendors of pet shops are selling fish to beginner aquarists, using their insatiable desired “I want this fish, this one and that one and those catfish”. At the same time, neither of them think about the further fate of the fish.

Sad! But for some reason, this is exactly the fate of "cramming nevpihuemoe" comprehends only aquarium inhabitants. Imagine, mother and daughter come to the pet store and say: "Give us 15 cats, 3 Yorkshire terriers, 5 chinchillas and one sheep-dog and 2 more parrots do not forget." Unfortunately, with aquarium fish this is exactly what happens.

And then, after a while, a convulsive scripture begins and the search for an answer to the questions: why the fish die and die, why do the fish lie at the bottom, float or swim on the surface, do not grow and do not eat!

HERE'S OWN, WHAT HAS BEEN AWARDED ME WRITE THIS ARTICLE!This is some kind of attempt to stop the mockery of fish! An article for future similar questions. An article that will somehow help newcomers and people who are going to buy an aquarium to understand that the fish are the same living things as we do - they grow, require certain conditions of detention, have their own characteristics, etc.

Very clearly, this problem is visible in Goldfish (pearls, comets, telescopes, veils, shubunkin, oranda, ranch, koi carps, etc.). People either do not know or do not understand that this family of fish belongs to large species. In fact, they need to be kept in ponds (as it was in Dr. China) or in large aquariums.

But it was not there! People for some reason have developed a Hollywood stereotype that Goldfish looks beautiful in a round small aquarium.

HOWEVER, THIS IS NOT THE CASE!!! The minimum volume of an aquarium for a pair of goldfish should be from 100 liters. This is the minimum in which they can live normally, and it’s not a fact that they will grow "to their full height."

Therefore, recalling the above example with a citizen, which has an 80-liter aquarium, in which: 4th scrofula, scalar, gourami and others ... it is not surprising to hear "My golden fish does not eat anything, lies at the bottom or swims belly to the top." And it touches the question, why do they not grow?))) But how can you grow here, you wouldn’t die!

In addition, in this example, there is a relative compatibility of fish. We must not forget that Scalaria is a peaceful, but still South American cichlid, and somehow it’s not a friend with goldfish. The same goes for the gourami - they are peaceful, but snooty individuals come across.

Summarizing what has been said, I earnestly ask everyone not to violate the norms and conditions of keeping the fish.
Do not be greedy!
And then your fish will grow beautiful and big.

Somewhere I read that for 1 cm. The body of a fish without a tail should have 2-3 liters of water in an aquarium. Who cares here is a link to the compilation - How much can the fish in an aquarium X liters (at the end of the article, select the desired aquarium volume).

Now I would like to talk about other reasons that lead to poor health of fish, without any visible reason (signs of the disease are not visually visible).

If the norms of the volume of the aquarium are not violated, the compatibility of the fish and their number are not violated, and the fish still float or vice versa lie at the bottom and swallow air, then the reason may be:


Poisoning fish with nitrogen, ammonia,
and more simply poop

We live in the air, and the fish in the water. Parameters of aquarium water directly affect the health of the fish.

In the process of life, aquarium fish and other inhabitants defecate, another organic matter dies, the remains of food decompose, which leads to excessive saturation of water with nitrogenous compounds that are detrimental to all living things.

Thus, the cause of poor health or a pestilence in fish may be:

- lack of care for the aquarium (cleaning, cleaning, siphon, no filter or replacement of aquarium water).

- overfeeding fish (the presence in the aquarium is not eaten feed).

- untimely disposal of dead fish, etc. (some novices watch snails burst dead fish, this is absolutely impossible).

What to do in this case? It is necessary to eliminate the sources of nitrogen excretion:

- urgently transplant fish into another aquarium with clean water;

- strengthen aeration and filtration;

- to clean the aquarium, and then replace it? aquarium water to fresh;

- Pour into the filter aquarium coal;

It should always be remembered that Aquarium water needs to be replaced weekly. However, this is not always good - old water is better than fresh, especially for young aquariums, in which the biobalance is not yet tuned. So this should also be done with the mind and as needed. If you see that the water in your "young aquarium" is not green, not muddy, etc. Replace at the beginning of 1 / 5-1 / 10 of the volume of aquarium water. However, one should always keep in mind that clear water is not an indicator of its purity. With that said, it is necessary to develop your own “tactics” of water changes based on the volume of the aquarium, its age and fish preferences, etc.

Emergency fish transplant - This is a temporary measure, if the fish is very profitable. As a rule, when a fish is not feeling well (lying on the bottom, swallowing air, swimming on its side, etc.), such an action brings it to life and after 2-3 hours it is cheerful and cheerful.

It should be remembered that such a transplant should be done in the water at about the same temperature as in the aquarium, the water should be separated (preferably), do not forget to provide aeration. And yet, if there is no other aquarium, an emergency temporary transfer can be carried out in a basin or other vessel.

About coal. Aquarium coal is sold in any pet store. It is not very expensive, so I recommend to buy it in reserve. Coal - this is a great additional measure in the fight against "shit and other evil spirits." If it is not at hand, you can temporarily take human activated carbon, wrap it in gauze or bandage and put it in the filter.

There are also so-called ion-exchange resins, for example, zeolite, they also refer to absorbents as coal, but they work, if you can say so at a more subtle level — removing nitrites and nitrates from the aquarium — decomposition products of ammonia, which in turn is formed from dead organics and waste products of hydrobionts.

Water filtration Everything is simple. The aquarium filter must be suitable for the volume of aquarium water. Additional helpers: aquarium plants, as well as snails, shrimps and crustaceans.

In the end, we can advise the drug for quick cleaning of the aquarium from sewage - TetraAqua Biocoryn.

Another reason that the fish die can be the wrong adaptation of newly purchased fish.

Well, firstly, you should not release new fish immediately into the aquarium. Everyone knows that. Let them acclimatize: Therefore, see the article All about Purchasing Transplant Fish Shipping!

Secondly, the fish that lived in the pet store or grew up in another pond got used to certain water parameters (pH, hD, temperature) and if you transplant them into water with radically opposite parameters, this can lead to their death in a day or a week.

Actually therefore for the correct adaptation there are so-called quarantine aquariums. You kill two birds with one stone: check whether new fish are contagious and adapt them to new conditions. The quarantine principle is simple - it is a small aquarium (another reservoir) into which new aquarium inhabitants are launched and within a week they are checked for lice, as well as they gradually add aquarium water from the aquarium in which they will live.

You can do without quarantine, but it is a risk! As a rule, it carries in 80% of cases, but 20% still remain. To neutralize these 20% I recommend to transfer fish with the drug company Tetra AquaSave (Tetra AquaSafe), read here DRUGS AND TETRA AIR CONDITIONERS. This preparation "improves" aquarium water and reduces the stress of fish during transplantation.

The third reason that the fish is bad is asphyxia, caused by the lack of sufficient aeration of aquarium water.

The obvious signs of asphyxiation (suffocation) in fish are: frequent opening of the mouth, heavy breathing, wide opening of the mouth - as if yawning, the fish swims near the surface and there is enough oxygen.

You should know that the fish breathe oxygen dissolved in aquarium water, which they pass through the gills with water and if it is not enough of the fish simply suffocate.

Enhanced aeration and bringing it back to normal will correct the situation!


Another - the fourth reason for the ascent of the fish with a belly to the top can be the use of tap water

Opinions on this are different. While talking and discussing this topic, some comrades say: "Yes, all this is fikhgnya, I fill in the unstable tap water in the aquarium and everything is fine - the fish will not die." However, it is worth noting that tap water in many regions of the CIS is simply terrible! It contains so much bleach and other impurities that it is scary to use it. Somewhere, of course, the water is better here and “carries” - the fish do not die. In the Czech Republic, for example, tap water is generally spring water from the Karlovy Vary sources, but alas, where is the Czech Republic, and where are we ?!

Therefore it is very important to use only separated water for the aquarium. In addition to the fact that chlorine will evaporate from the water and heavy impurities will settle, excess oxygen will also be released, which are no less destructive for fish.

What to do if you poured tap water and fish from this poplohelo? Ideally transplanted into separated water. However, if you originally poured water, then you probably do not have separated water. One way out is to add aquarium chemistry that stabilizes the aquarium water. For example, the aforementioned Tetra AquaSafe or TetraAqua CrystalWater.


The fifth reason for the death of fish - a violation of temperature

The generally accepted temperature measure of aquarium water for many fish is 25 degrees Celsius. But too cold water or too warm leads to all the same symptoms: the ascent of the fish, lying on the bottom, etc.

With cold water, everything is clear - you need to buy a thermostat and bring the reduced temperature to the desired one. But with too warm water is much more complicated. Usually aquarists encounter this problem in summer, when the water in the aquarium boils and rolls over 30 degrees, from which the fish become lethargic and "faint".

There are three ways out of this situation:

- cool the aquarium water handicraft: using frozen 2n. bottles from the fridge. But - this is not very convenient, because frozen water quickly gives off cold and you need to constantly change the bottle. In addition, jumps and temperature fluctuations - there, no less harmful than just elevated water temperature.

- sold special installation cooling aquarium, but alas, they are expensive.

- buy an air conditioner and install it in a room with an aquarium, in addition to room stuffiness, the air conditioner will knock down the aquarium heat. The last option in my opinion the most acceptable.


The sixth and seventh reason

Sometimes the cause of bloating the fish and swimming a belly or side to the top is overfeeding. Again, this reason is largely related to goldfish, because they suffer from gluttony, overeating and begging. Do not enter them on occasion. Feed them exactly as much as it should be. Otherwise, your gluttons will earn inflammation of the gastrointestinal tract or, more simply, they will suffer from constipation!

Another reason for which the fish can lie down for no apparent reason is stress. Well, do not like her neighbors and that's it. Or it often happens that they take young fish, and all the boys and one female grow out of it, and as a result, the boys start a showdown - who is in charge. The weak begin to chase and tyrannize, with the result that they are hammered into a corner, lie on the bottom, well, and die. There is only one way out, to resettle everyone, give them to friends or back to the pet shop.

What else can affect the health of fish:

- Excessive lighting or stress from it;

- decorating the aquarium with chemically dangerous decorations (metal, rubber, plastic);

- overdose of drugs;

Summing up, it is possible to make an unequivocal conclusion that the correct maintenance of fish is a panacea for many aquarium ills. If you are attentive to your aquarium dwellers, they will thank you too.
beauty and longevity!

Why not fill the aquariums for breeding fish with fresh tap or well water.

Website about piranhas www.piranhas.ru

All right above said. Tap water can be added to the aquarium with a constantly running aquarium filter and a temperature similar to that of the aquarium.
The only thing you need to fear is rusty water, because of it, the fish can die immediately.
Natural (well) water is of different hardness, so if we are not talking about the content and dilution, water hardness is important here. For many breeding fish need soft water, some quietly breed in hard water.

Alex

That's because the question! Obviously amateur! Som or labyrinth you would not otherwise reconnoiter, of course, the water is not chlorinated. Control the rigidity, pH, for so many fish it is important. "Old age" of water in several indicators can not be described, but it happens so important !!!

Irish @

Well, please, if you are sure of its safety. And tap water may contain chlorine! Which should erode. But if you have a good filter, you can run the water through it and heat it up to the desired temperature ... Go for it!

Why does a caught fish die in tap water?

☥ Ra ☥

What do you think, what are aerators used in aquariums for? Yeah, in order for the fish to have oxygen, it does not breathe with water, but with the same oxygen as you ... Understood what I am getting at? Why did you tell about this?

HUNTING TO FISH

the point here is that the first is when the movil is important so that it doesn’t snatch it from the depth but take a maximum of five meters if it is a fish from a hundred meters you pull out a bubble from the mouth of the fish and it’s not a tenant!
the second is about the lack of oxygen in the water; in such cases, it will just pop out and breathe air -
Now, about the temperature drop - in fact, it is fatal if the difference is 5-10 degrees
An example is while you were carrying water warmed up to 20 at least and your bath is in the ground there is at least 7 and at most 10, and you will feel that the living organism is perfused!
about chlorine - in Mangyshlak we always have water with chlorine, but always fill the aquarium from the tap and immediately start the fish - we will shake these chlorines!

Nikolay Egorov

The temperature difference is not fatal, when moving from a warm to a cold river fish just stagnates for a while, then it goes away and 10 degrees of difference is fatal only for tropical fish. But oxygen is important for them, It was necessary to put the compressor in the bath, and the problem would be solved. My crucians lived in an aquarium for about 10 years. poured them simple icy water from the tap.

SEREGA_

What would the fish live for example in a large aquarium, it is cooked, cooked and water. It must have a sufficient number of beneficial bacteria, as well as constantly saturated with oxygen. If there is none, the fish is dying ... whatever you put there.
We also have a bathroom at the site, so Daddy doesn’t wash her up with a specialist ... she always has a touch of mucus and crap like tina - crucians live there for a long time (right up until the departure to the city in the fall)

MAHA

Oxygen can be provided without an aerator. For this you need water plants and light. That is, for the night you need a lamp above the reservoir. I have so been a guster for 3 months in a small aquarium. And once they forgot to turn on the lamp for the night and - skit the fish.
