Fish die in the aquarium what to do


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 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 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 aquarium of the desired 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;

- fill in 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. It's 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 the 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 the 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 die fish in an aquarium and what to do.

It is very unpleasant when the fish begin to die in the aquarium. It would seem that everything was done correctly: clean water was poured, aquarium equipment was working, the fish received timely feed. Despite this, the animals die. Unfortunately, this situation occurs in newcomers of the aquarium business quite often, which is why it is necessary to arm yourself with knowledge of the causes of this phenomenon.

Each novice aquarist should understand the following in advance: if conditions are created in the water house for its inhabitants that are as close as possible to their natural habitat, then they will not get sick, much less die.

At the very least, the risk of death will be minimized.

Practice shows that in the overwhelming majority of cases, the death of fish is caused not by any external diseases, but by errors in content, illiteracy and carelessness of their owners. There are various reasons for this unfortunate phenomenon or a whole combination of causes and factors that should be considered in detail.

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.

Water temperature

The death of fish can also occur due to a decrease or increase in temperature of the aquatic environment. The opinion that a deviation from a certain temperature mode by 2-3 degrees in one direction or another will not affect the health of aquarium pets is deeply mistaken.

If the temperature drops, there is a danger of dying from a cold, and as it rises, the fish may die from lack of oxygen.

Lack of oxygen as a negative factor

A fish is known to breathe air dissolved in water, and it can suffocate if it is too little in aqua. Although such cases are very rare, they do happen.

As a rule, even beginners pre-acquire all the equipment necessary for the operation of the home aquatic system.

And very often, buying a powerful enough filter, they trust him not only with water purification, but also with its aeration and mixing.

Still, experts recommend to separate these two functions and ensure the continuous operation of the air compressor

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.

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.

What to do if you find a dead fish in the walls of the aquarium?

  1. Look at the number of fish in the tank. Recount them in the morning and in the hours of feeding. What is their condition, do they take food well? Are there fish that refuse food? Is it possible bloating in one of the fish? If you have not found any fish, check all the corners in the aquarium by lifting the lid. Inspect the plants, caverns and all the scenery. If after a few days the dead fish did not float to the surface, it may have suffered from a neighbor in the aquarium, and you can hardly find it. Sometimes the fish fall into an unprotected filter, and die there. In any case, keep searching until you find the visible reasons for the disappearance.
  1. Fish that have died in an aquarium should be removed from it. Tropical species of fish quickly rot because of high water temperature. Under conditions of such an environment, bacteria multiply rapidly, water grows turbid, and an unpleasant odor appears, which can cause infection of other pets.
  2. It is necessary to do an inspection of a dead fish. You must understand why she died in an aquarium. Wear medical gloves. If the body is not completely decomposed, look at the condition of the fins, scales, and condition of the abdominal cavity. Perhaps there are wounds on the body or signs that she has suffered from unproductive neighbors. If the stomach is strongly swollen, eyes bulging, the scales are covered with bloom or stains - it means that the pet has suffered from illness or poisoning. After inspection, gloves should be discarded.

  1. Check the water parameters. Water is often the main cause of poor health. Take tests with indicators, and make the necessary measurements. The increased content of ammonia and nitrates in water, heavy metals leads to the fact that pets die quickly. If the aquarium has a decorative element made of iron, zinc, copper - this is another pointer. Some fish do not tolerate metal, and suddenly die.
  1. After the test results, draw conclusions. The test will show two results - either you have everything in order in the aquarium, or the water is dirty and there is an overabundance of toxic substances in it. In the second case, you need to enable powerful filtering, and make a replacement of 25% of the aquarium water for clean and infused. Dramatically change the parameters of the water is not necessary, it can harm living fish.
  1. But if the water is in proper condition, there may be a number of other reasons why the fish died. Sometimes aquarium pets die of hunger, overeating, illness, severe stress, bruises after attacking other fish, age. If the fish die suddenly, you need to do everything necessary to keep others alive. Contact your veterinarian if you do not find obvious causes of death of the pet.

Why fish die in the aquarium

The causes of death of aquarium fish can be many. Ideally, the environment in the aquarium should be as close as possible to the natural habitat of the species of fish that you settled in it. If there are any deviations, it can lead to health problems and even the death of your pets.

The question "Plots turtles." - 3 replies

Aquarium fish should be provided with perfectly clean water, the aquarium itself should be well lit and filtered. And, of course, we must not forget about feeding and live plants. It would seem that to fulfill these requirements is quite simple, what can go wrong? Most often the fish die as a result of the following violations.

Main reasons

The first reason - poor-quality water. If you do not clean your aquarium often enough, then the waste products of the fish disintegrate and poison the water with nitrogen compounds. During the day, the fish accumulate a huge amount of feces - up to a third of its weight. In addition, do not overfeed your pets, otherwise the uneaten food will begin to decompose. Unfortunately, many novice aquarists are poorly oriented in such matters and completely forget about timely cleaning. Nitrogen compounds, such as ammonium, nitrate and nitrite, make themselves felt unpleasant smell and muddy
The second reason is the wrong adaptation of the purchased fish to new conditions. The problem is that the water in pet shops aquariums and the water in your home can vary dramatically in terms of pH, temperature, hardness. You can not just take and throw a newly acquired fish in your tank, it can experience shock. It is necessary to attach a bag with a new fish to the glass of the aquarium, install weak aeration and pour aquarium water into the bag every 10-15 minutes. After an hour and a half, the water from the package can be poured into the sink, and the fish run into the aquarium. In the aquarium for a better adaptation of new fish, it is desirable to add a special anti-stress drug

What does the wrong content lead to?

The third reason is quite common - various diseases. But It is worth noting that the disease option should be considered only when the possibility of contamination or maladjustment is excluded. And here it is necessary to make a reservation that the fish get sick because of the reduced immunity caused by adverse conditions. If one fish has died, or the sea has begun, you need to consult with a specialist who is not interested in selling expensive drugs. For the prevention of disease, take care of the fish, and place the diseased and recently acquired imported animals into quarantine.
Finally, you should list the adverse factors that may adversely affect the health of your fish, which can lead to death. These factors include tap water, a heater that broke down in winter, a lack of oxygen, and finally, aggression from other fish.

Why do fish die in an aquarium?


Even if there are only one fish, there are already 13 of them! Adult Antsistrus 15 cm, gourami 10-15 cm, swordtails, molly ... They just closely, this time. There are no living plants, you can forget about the natural balance, these are two. Then you need a good exterior with bioremediation with your dense population. You have a monstrous vinaigrette, the fish have different requirements for the conditions, these are three. The Haracinids cannot live normally together with labyrinth, armored catfish ... They may or may not survive. Your example is evidence of this.

Vladik Ledyaykin

They died a boy, because you did not care for them. If you ask for interest, then either you have not changed the water, or you have not wiped the poop. Either they did not give to eat. Or maybe (just for fun) you ate them! Hahaah

Princess Frog

And the hardness of the water is not checked, and in my opinion a bit too much 27 degrees. My tetras lived for quite a long time with gouras, scalars and neons without a heater in general, they were warm at home and cooking ear was completely useless.)) Pecilia and swordsmen chronically died out, the water did not fit, I had to give them up. A scalar even put off the calf, though after all they started to kill, had to spawn)))))))))))))


Is there a thermometer? The heater can warm up more than the set temperature ...
Water potestit on nitrates, nitrites ... Perhaps you are overfeeding, that water and spoils.
And tetras and neons you have that for 1pc. ? The fish are schooling ... And if you have these types of fish for each, then overcrowding is also possible ...

Kondraty Parishes

In principle, everything is correct, but ...
1. The newly created aquarium should be empty (without fish, but with plants it is possible) to stand for a week. All equipment must work!
2. I understand that the vinaigrette is an excellent and tasty snack, but it is not appropriate in aquarism! Well, it is impossible to make “sprat in a tomato” from such a modest jar!
3. Local water chem. composition may not correspond to certain types of fish. This also needs to be taken into account.
4. There is no data on age (approximate, of course) of purchased fish. This, too, can be a problem.
Maybe even the substitution of water is too big ... Less.
I don’t see any more reasons for now, but it would not be bad to make a video with comments. Bust off - do not worry. The most important thing is that there will be a couple of practical advice based on the material, and not in the mode of divination according to a not entirely correct description.

Rus White

All wrong!
1. water that has been settled for 10 days but not matured in your tank ... why? 80% of beneficial bacteria - in the soil and filter
2. artificial plants, absolutely, like grottoes - into the firebox
3. a lot of fish - I do not even want to talk
4. feeding 2 times a day instead of once a day ... for what purpose?
5. at night, turn off the filter? and for what? the water is not cool, there is little oxygen
6. live plants are not planted - slip
7. the ground was boiled ... who told you that? just washed with warm water and forth
In general, re-read the aquarium literature and do everything according to science

Svetlana Markelova

As for the hard one-time feeding here are clearly hot. The seller in the aquarium shop (competent, by the way), for example, recommended to feed us twice a day. True, very small portions. If dry food, then with the calculation of two plates on one fish. I feed, as he said, the fish are alive and healthy. But overfeeding, however, is very dangerous. That can easily cause the death of fish. On the ground. I do not know how about boiling, but I heard about piercing the ground many times. We, for example, did nothing at all with the ground. Just washed with water and everything.


Soil if from nature it is uniquely calcined and boiled. Two times you can feed the main thing in a variety of ways and understand how this or that food is digested. The digestive tract of fish is often overfeeding and from them the fish die in batches and sometimes not even because of food in the stomach but because of food in aqua that spoils the water. There are no norms and doses of feed; this is rather intuitive. Plastic plants are quite appropriate and the fish live well with them, but special conditions must be given to the soil filter as the main workers maintaining the water quality level. Well, not applicable standard and regular water changes. And of course, the first mistake of many is absolutely not the correct launch of aqua due to the lack of knowledge of the processes occurring in aqua water in the first stage of the so-called origin. Of course there are many fish and fresh aquas simply did not cope with such a load, and natural selection in the artificial reservoir was used! The fishes even did not have time to get sick as they were poisoned by ammonia and nitrites and died. Advice juzat start akv and selection of fish companions and quantitative composition per unit volume well, and about feeding !!!

Ilya Zverev

look in the internet on the topic of "starting the aquarium and filtering" and "nitrogen cycle in the aquarium" and you will understand everything, in 2 words do not say. it is generally very useful to you, or rather, without an understanding of this, it turns out to be either accidentally lucky or more often a mockery of a fish that stubbornly does not die, despite all the efforts of the owner.
the temperature for an ordinary fish is better to be set at 25, and so +/- there is no accuracy of heaters.
and to turn off the compressor at night, I didn’t want to drink 50-100 liters per hour quiet and let it plow
a little bit, what is not the first thing we stop feeding for a day or two at all, this is the main evil
everything else you will understand if you read not the rivers. Topics.

Why do my fish die massively in my tank? ...


. Support for fish habitat settings. You need to check the water temperature every day and if you need to turn on the heater, also make sure that the filter is not clogged, so that the compressor works, and if necessary turn on the backlight.
If there is a need to add water to the aquarium, but it must be defended. It is contraindicated to put into the aquarium various foreign objects that are able to release into the water of various kinds of substances. In the room where the aquarium is better not to smoke, because tobacco smoke is harmful to fish.
2. Feeding. It is best to feed the fish once or twice a day if they are adults, and the fry are more often four times. Frequently satisfied beginners aquarists do not know how much to feed. In order to establish the exact amount of feed needed directly by your fish you can empirically. You just pour the amount of food that they can eat in 5-10 minutes. It is better to clean up all residues immediately, because they pollute the water in the aquarium. Not allowed accumulation of food at the bottom. It is better not to overfeed fish. Feed is either frozen, or "live", or dry.
Dry food is most often produced on the basis of dry daphnia or dry mixes. To "live" feed include: tube maker, bloodworm, duckweed. And frozen food, before giving them the fish need to defrost. A variety of food, no doubt, is useful for you and your fish. Food should be distributed in the aquarium in such a way that everyone gets it - both strong and weak, and also to those who are always at the bottom.
3. Verification. Every day you should check the condition of the fish and plants in your tank. If you see any signs of decomposition of plants, they should be urgently thrown out. As for the fish, if they have signs of disease, and these are growths or suspicious spots, they should be immediately transferred to the quarantine aquarium so as not to infect other inhabitants of the aquarium. Only a specialist will tell you how to treat a sick fish, you yourself are unlikely to determine what exactly the fish are sick with.
Experts in this business recommend “general” cleaning of the aquarium, depending on the type of fish, it can be once a week or 1-2 times a month. During this cleaning, the fish should be transferred to another aquarium and begin cleaning. It is necessary to drain the water, clean the walls and bottom of the aquarium from accumulated dirt, food residue and fish waste, wash the filter.You shouldn’t disturb the fish often, because they don’t like it, so too often cleaning the aquarium is as bad as forgetting about cleaning.
And so it turns out that the maintenance and care of aquarium fish is not so complicated as it seemed at first glance. You only need to adhere to the two rules in the process of caring for fish. The first thing you need to know is what conditions are considered optimal for keeping your particular species of fish, and sticking to them in an aquarium. The second in all aquarium did such as lighting, cleaning and feeding you need to adhere to common sense, that is, moderately to feed the fish, not very often disturb them cleaning, but also not to allow the aquarium to become like a swamp.


Well, probably because I have not bothered to find out in more detail and meticulously about their content in the aquarium! The reasons for this mass ranging from water quality and ending with epidemic diseases! In order to get a more competent and accurate answer in the direction, it is necessary to describe the clinic of fish death: what behavior, fins are stuck together, whether there is a rash on the body, mouth is open, what breathing is, eat or not before death, sometimes according to the symptoms, you can predict the root cause of their death! And your question can only shrug or selectively call for one of hundreds of reasons)))))))

Because the reasons are mass, ranging from improper start-up, overfeeding, crappy conditions, etc. ... Blow in the section to fortune-tellers, they will prompt you.
Svetlana Arkhipova gave you very sensible advice, she laughed for a long time! :))) The main thing is to clean the aquarium more often as she advised and your fish will live less, and also feed them with live food, especially predators and the result will surpass everything expectations;)))

Help!!! fish in the aquarium die every day !!!

Katya Soboleva

Most likely, the fisherman has a fungal infection. Its common form is gill rot. One infected fish can infect others. so they die one after the other.
I think you should completely clean the aquarium, if there are already no fish in it. to fully boil the ground all the caves and other decorations. The aquarium can also be put into the bath and pour boiling water from the kettle. If there are still fish left in the aquarium, put them into the otsadnik and drip there conditioner methylene blue or ANTIPAR is a complex preparation for ornamental fish for diseases caused by infusions and fungi. Hold the fish in such a bath for 5 days, if a strong improvement will not be noticeable, repeat the procedure with new water. And the most important thing is to place an aerator in an otsadnik so that there is always an oxygen supply. Also ask the consultant - aquarist, he can advise something else. Good luck!)

Consider the fact that 1 cm. Needles 1 l. water!! !
And you have akv. only 25 l. !!! Naturally they die !! !
Calculate how much is in general the length of all your ribs and translate it into liters! Buy such an aquarium!
You can even more! Then they will feel great))
Good luck to you!

Tell me what to do fish die on day 6 after running into the aquarium? ? The water was settled before the launch of the fish 1 day !!!

Natalia A.

Because of the fact that 1 day has defended itself and is dying from poisoning, start the aquarium as it should be, there are plenty of literature on it, google an aquarium for beginners, also on YouTube it’s full of videos for launch, the fish gradually sits down no earlier than after 2 weeks from the moment of filling and connecting the equipment, when biological balance is established in the aquarium, in a good way this process (launch) takes a month! and not a day.

Tatyana Yakunina

It is not enough to defend - you need to enable filtering. About a month they are bent up - I stand for half a day, but I fill in already separated water (weekly distance) - I stand in a barrel, then it is still important that the water is warm - 24 degrees about plus minus 1 degree - for this I add water to the boiling water. And for gold in general, water must be salted !! ! 1st c. l on 10l. That's all the secrets. And then run the fish.
By the way! Guppies and gold will not take root !! ! Gold must be kept separately - other fish will raise their fins !! ! I have gold - there are many types of them - one telescope, one voiletail, one Water eyes. On one goldfish you need at least 10 liters.


Fish eat, and then poop and poo. At the same time ammonia is formed from their waste, which is very poisonous.
This ammonia is gradually processed into nitrate (also, by the way, not a gift in terms of toxicity), and then - into nitrate (much less toxic). This processing in the aquarium is carried out by bacteria, which are gradually infused into it independently. These bacteria live in the soil, in the filter, in the water (the smallest number if there is soil and / or filter in the aquarium). While the aquarium is young (in sufficient quantities, the bacteria multiply in about 3-4 weeks), they do not have time to process all THAT into the least harmful nitRAT, so the fish can be poisoned by ammonia and / or nitrite.
Thus, the main thing, when properly started, is to ensure that the aquarium colonizes with beneficial bacteria and does not allow harmful substances (ammonia and nitrite) to increase to concentrations that are dangerous for fish.
