Why do Guppy aquarium fish swim on the surface?

Sometimes lovers of guppies notice that their fish have changed behavior, and they constantly swim on the surface. What to do in this case, and with what it can be connected?

Before taking any action, you need to know that guppies are fish that live in the upper layers of water, so if they hover around the surface sometimes, then there is nothing wrong with such actions. But you should pay attention if guppies are near the surface all the time. There may be several reasons: lack of oxygen, poor water quality and various fish diseases.

Lack of oxygen

This is the most common reason why guppies tend to the surface of the water. If there is not enough oxygen, not only fish will feel discomfort, but also plants - they begin to wither and die. Why do guppies float on the surface, even if aeration is turned on? Perhaps its level is insufficient to provide all the fish with oxygen.

In addition, it must be remembered that the higher the temperature - the stronger should be aeration.

Poor water quality

Sometimes guppies behave this way if the water in the aquarium is of poor quality or has become swampy. If there is no filter and aerator, they should be immediately installed and in the future it is important to constantly monitor their work.

As a preventive measure, it is possible to add digran or antipar to water (how to add them and in what quantity, it is necessary to read the instructions for the preparation).

Guppy Disease

If the oxygen level is normal, the water is qualitative and not stagnant, filters and aerators are installed, and guppy aquarium fish still float on the surface, then the cause of this behavior is a disease that is not so easy to determine. According to experts, the "symptom of suffocation" characterizes many protozoal, bacterial and helminth diseases.

If only a part of the fish has surfaced, they should be urgently planted from the others, and then treated.

If all guppies behave this way, then it is necessary to treat all with antibiotics and aprotozoal preparations. Digran is added to the aquarium at the rate of ½ tablet per 100 liters, and Antipar - 1 ml per 40 liters. These procedures are carried out for about 2 weeks, then change ½ the volume of the aquarium and take the dosage of drugs in 2 times less. If the treatment is successful, then gradually the drug must be removed from the water, changing it periodically.

Thus, if you noticed that guppies began to constantly stay on the surface, first check the oxygen level and the condition of the water, and only then proceed to the treatment of individuals.

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!

Please tell me why the fish swim on top?

Yury Balashov

It is not necessary that there is little oxygen in the water, some parasite can gnaw the gills, or it can carry * eaten food decomposes into methane and the fish are poisoned or there is some kind of decoration painted with crap paint that dissolves intoxicating the water and life in the aquarium. And it may happen that she got into the aquarium water without having washed her hands from the perfume cream, in any case: rinse the filter, strengthen the aeration, siphonit the soil, change the water for 30-50% for a few days, but first determine and eliminate the cause of the poisoning (lack oxygen). There may be a banal overpopulation.

Nikita Levadny

If you have a filter with a compressor, you should wash it ... because when the filter is contaminated it has poor traction and the air is not blown into the aquarium and the fish swim above due to the fact that there is little oxygen in the aquarium ... or they want to eat +)

Kiwi

most likely they lack the oxygen that is dissolved in water?
Do you have a filter? check if he has enough oxygen? if possible, increase it. In the meantime, mix the water in the aquarium with your hand, then the lower layers of water will also be slightly filled with oxygen

Vadim74

There are a lot of reasons for this: there are small fish that, by their nature, keep the upper layers of water, let's say the same Danio, some species of Schuchek! As well as the fish can swim and can breathe hysterically and barely move as a result of asphyxiation of lack of oxygen suffocation! To begin with, determine the comfort of the life of the fish as the gill covers work how hard the mouth is opened in a calm state, and according to the conclusions and measures it can do everything well and you are in a panic))))) and it can be bad, while Yuri advised!

Fish swim at the surface of the water and swallow air (details inside)

akva-service akva-service.com

fish under the surface - 2 reasons. This or lack of oxygen, or poisoned. in most cases, the first reason. Or together.
What to do.
1 - purge put times. No purge, put the filter like that. what would the water from above swayed
2 - change the water to a colder one (Unless, of course, something got into the water)
3 - no feeding
4 - clean the filter
5 - no drugs and conditioners
If poisoned, then you need to look for the cause. from what. If the water - the thing is complete rubbish. Can from feed yet, or an overabundance. Can from detergents with which the decoration was cleaned. But you need to look for the cause.

About fish! Why is the water in the aquarium muddy (just poured yesterday, the water has defended), and the fish on the top swim?

Tatyana Litvinova

because before launching a new fish tank into an aquarium, it should stand without fish with water poured into it, planted plants and equipment turned on for at least a week. During this time, the filter settles useful bacteria necessary for normal operation of the aquarium and the life of the fish. The fact that the water in it dimmed, so it should be. In a few days it will become transparent, and in a few more days it will be possible to settle the first fish in it, but not all at once, so that there is no jump in the water parameters.
Read a lot of useful information on the launch of the aquarium, care for it, fish, what conditions are necessary for them (because of water, volume of the aquarium, neighbors). Good luck.

Elena Surmach

This is a bacterial cloud, as it should be. The fish started early, do not feed them until the dregs subside. The fact that at the top of the swim - not enough oxygen, put the compressor.
//my.mail.ru/community/aqvamiir/

What do the fish float to the surface

Condorita

They do not have enough oxygen.
Are there any plants in the aquarium? Be sure to plant. By the way, you started the fish early. First, it was necessary for the plants to take root.
Run there a couple of snails - they purify the water.
Well and, clearly, buy a device for oxygen enrichment of water.

Chingachguk Green Serpent

I had it. Plants you bloom, on that and the water is cloudy. And plants can devour oxygen, and not produce it, if the light is low or under other non-standard conditions.
Change the water and plant other plants. And thoroughly rinse the soil under running water.

Irina

I would advise not to change all the water, they change 1/3 of the total volume (so-called water change), before that the water should stand as a min day in a glass jar, usually I add 0.5 liters to the water to 3 liters. large cook, salt) -for prevention. Muddy water from excessive decomposing food — in an aquarium — a lot of ciliates — salted will help, if of course the fish are not sick at all, yes, and the aquarium should not stand under the direct rays of the sun.

Lelka

After filling the aquarium and planting, it is necessary to wait 5 days: believe, no air conditioner (even a tetrovsky aquaceyfe start) will make the water immediately suitable for settling the fish. Place the fish in cans with SHEARING water, replace the water in the aquarium at 1/3 and wait 5 days, plants and snails, in principle, you can, and even need to leave. In banks only connect spray guns, so that the air is driven. But the fish ... a bit too much, we have 75 liters, live lyalius, tarakatum, labo and cancer, + 3 ampoules and coils. Ancistrus and speckled catfish are waiting for their turn after quarantine for replanting. But the telescope and the tailpiece live separately. They are very large grow.

Elena Gabrielyan

You originally improperly equipped the aquarium.
First stage: an aquarium is installed, the ground is thoroughly washed, water is poured, all equipment is installed (filter, water heater - the filter should be 800 L / hour, ask the seller) and leave for 7-10 days without landing the fish. After 10 days, plants are planted, the temperature of the water in the aquarium is checked and adjusted if necessary.
Stage 2: planting plants. (depends on taste) and decoration of the aquarium. During this time, water can become white - this is normal. As soon as the plants adapt and go into growth, the water will clear itself. Air conditioner is added to the aquarium to speed up the preparation of water, but does not replace the biological processes associated with the start of the aquarium fincing. You need at the time of proper arrangement of the aquarium if you can, transfer the fish to an already prepared aquarium. and redo yours. The aquarium prepares for settling within a month. no rush. The fish float to the surface because the water is not ready, an abrupt change in the chemical composition can lead to the death of the fish in a very short time.
Scaryarium and telescopes are not compatible with each other. Goldfish are kept away from everyone. Live plants they also will not plant, digging in the ground will break, partially eaten. Fish dry food do not overfeed. The water can become muddied, and because you give it too much, you do not have time to eat and rhv, while decomposing at the bottom, sweats the water, hence the unpleasant smell in the aquarium.
You can try to buy water in a specialized store to buy air conditioning for water purification and add to the aquarium. BEFORE use, read the instructions or ask a qualified specialist how to use them correctly. I wish you success in this hobby

Victoria

Defend tap water recommended in tech. 3 days, but you can speed up the preparation process - heat the water to 50-60 degrees (do not boil!) And let stand for at least 5-6 hours - you can pour into the aquarium. Verified by many years of experience!

Guppies swim near the surface of the water, occasionally sinking to the bottom !!

Elenka

Guppies are fishes living in the upper layers of water, spinning under the surface is their normal state, unless, of course, they sit all the time near the surface and do not swallow air. If so - lack of oxygen. This is confirmed by the fact that the plants wither.
Do you have a filter and aerator in this tank? If not, then perhaps the water began to swamp (as a small volume of water without a filter).
In general, this can happen even in 2 cases: 1) if the fish are overfed 2) if they have a parasite in the aquarium (usually they are brought along with some types of food - shrimps, crustaceans)
If the filter is working normally - then it is better to be safe (see if there are any signs of breathing heavily): antipar and cyfran in water (dosage in the instructions for the drugs)

Nastyushka Poltoratskaya

Guppies by themselves mostly stay on the surface of the water !!!! Well, if there is no aeration at all, the reason for this problem may be this !!! !
and the water is so, because the biobalance has not been established yet !!!! run aqua and let it stand for a day or two !!!! I, too, as the first time I ran my aquarium, then the water on my second day became cloudy! and after restarting - ALL NORM! so good luck !!

What did you mean when you wrote "floating" plants? If it is a pistol, then it is one. She needs warm water and bright light. If it is a rodentard, then it practically doesn’t need anything, it grows with crazy speed all year round. As it grows (and this happens very quickly), the hornet leaves the stem becomes heavier than water and it seems to sink to the bottom, with the majority of the plant still floating on the surface.
Water can become turbid for two reasons: 1. Nitrogen explosion, which occurs at start-up. This is quite normal. 2. bloom or sour water. In 20 liters to catch a word like this - how to make a fig, forgive my English. The reason most often lies in the overfeeding (the remainder of the food not eaten should be removed from the aquarium as soon as possible). At the moment, the following is required: stop feeding the fish for a couple of days in general, then give the feed every other day in very small portions once a day! From hunger, they just will not die! Substitute a couple of liters of water (10%) preferably on the one in 40 liters. Halve daylight hours.

Why aquarium fish swim on the surface

Elena Gabrielyan

To answer your question you need to know at least:
1. When the aquarium was created.
2. Its specific and quantitative composition, whether there are live plants.
3. The temperature.
4. Is there a filter, water heater, compressor (if necessary).
5. mode and frequency of water changes, the amount of replaced water, soil siphon.
6. Information about the hydrochemical parameters of water (if you know them).
And so offhand, I can assume that either the aquarium itself was recently launched, and had already bought fish, or if it was worth a long time a poisoning with waste products, it may also not be enough oxygen dissolved in water. Try to siphon the soil and partially replace the water no more than 10% of the total, just look at the filter's performance if it is clogged up it needs to be flushed (this is the case if it has been running for a long time).

Natalia A.

If there is certainly lack of oxygen from the air, buy a compressor, or if there is a plug, ammonia poisoning is also possible, and of course you had to indicate that the fish and their living conditions have species that tend to stay in the upper layers.

Maxim Bragin

Well, what fish, in the aquarium there are at least 3 tiers: on 1 (top) swim, for example, guppies, on 2 (average), for example, scalar, and on 3 (bottom) - catfish, so it depends on the species, fish, but if the tier of the aquarium does not match the breed of fish, then it means a lack of oxygen or water temperature.

Why die fish?

Doctor

First, in the aquarium terrible overcrowding. gourami up to 10cm grow, so only on ONE STEAM this aquarium fits, you have two more gourams there, not counting twenty other fish.
secondly, because of such a number of fish, the water in the aquarium quickly deteriorates, they all shit a lot and because of this, ammonia accumulates at the bottom, with which they poison and die. And this is not to mention the fact that the water simply rot.
By the way, mollies usually float near the surface, for them it is in the order of things.
but the names of soms could write.
if you want the fish to be beautiful and healthy - leave molyasia and a few catfish. What soma do you live with I have no idea, so I write about how many and which of them can be left (of course only one of the options): 1-2 tarakatums, 4-5 speckled, 1 sucker (whether it is antsistrus or brocade), 1 plateidoras or agamix, 1 synodontis. You can, of course, and two different types - tarakatum and 2-3 speckled or instead of them one sucker.
in general, siphon the ground in time, change the water, if there is no filter - install, do not overfeed and do not populate such a pile and then no one should die

Alexander Koblov

Judging by the fact that molly float on top, there is no aeration in the aquarium or it is very weak. In general, it is difficult to say from what the fish die without seeing the aquarium, because there are a lot of reasons (as well as in humans).
Soms can also be different, for example, if you have bag-wadded catfish, then they are generally difficult to kill (they can live for months in 2 liters of water at low temperature and feeding, without any equipment)

Help why the fish swims to the top and does not move until you touch that with the bottom

Max frost

Well, in general, an aquarium is small ... it is undesirable to contain telescopes with labyrinths. with rooster:
1) Is she not pregnant? look belly, if yes, then drop off
2) there is little air, although it is hardly so, since it is labyrinth
3) dies
4) severely injured or sick (carefully examine it, are there any strange "deformations"?)
5) fish get the rest of the inhabitants of the aquarium (follow them, maybe they bite the fins, then otsadite it (cock))
6) and what a floor cock? if the female and male, then see p. 1-5, and if the male and male, then it is clear that the fighting fish-each other pecked and the second one (which near the surface of the water) feels bad ... will die soon ...
PS: I would, in your place, have long ago cast off a fish ...

Why do I have a golden fish swims on top and chpokat if you do not help, I will kill her nah tired of not sleeping

Theo crowfoot

The fish do not have enough air.
Water in an aquarium without oxygen. You can change some of the water (but do not immediately pour it from the tap into the aquarium! All the harm to the fish should evaporate from it, this can be done by settling the water for 1-2 days (until the evolved bubbles of gases disappear)) or boil water within 10 minutes, cool and pour into the aquarium (but in this case, the oxygen in the water will be less). If you have filters on the water (under the sink), then you don’t need to do anything with water, it goes through the filter, it is cleaned and you can immediately pour it into the aquarium (but make sure that it is not icy, let it stand, warm it in the room) .
Buy a compressor and an aerator (air spray) if all these manipulations with water do not help. Although it is strange that you have such problems with one fish, perhaps you initially (when starting the aquarium, something was wrong).

Golden fish shifter ... who so was that she swims to the top of the belly. but the appetite is great. what was treated?

Vladimir

there was the same story ... completely changed the water ... for several days did not feed ... ceased ... then again ... I did not find out the reason ... so for a period of one and a half years periodically and swam up belly ... first I thought that it would die in a couple of days ... but not something like that ...

KIR

Keeping aquarium fish is a whole art. Why your fish feel bad can depend on many reasons. The first most common is overfeeding fish. What kind of feed you feed on, composition, water temperature. In general, God help you in this difficult task.

Fallen from the broomstick

this comes from overfeeding or poor water quality. Saw some such cases and all with a lethal outcome. Most likely a very high nitrate content in the aquarium. What is the volume of the aquarium and how many fish? Do tests for nitrites with nitrates. Due to chronic poisoning with nitrates, functional impairments and the functioning of the bladder, and the intestines and kidneys could go. And then the chances of recovery is not very much. It can only be counted upon after the normalization of the composition of the water in the aquarium. In addition to a varied and abundant feeding with plant food, I would advise that daily giving fish kanamycin food in fish in small portions 3 times a day.

Oksana

overfeeding fish. you have to plant a specific fish on a strict diet: feed exclusively in the morning, every two days, give a very small portion. After about a week you can increase the portion ...
Good luck in keeping fish. I also have 10 golden fish live in all different forms and nothing, everything is in order. no problems with them!
the rest of the fish also feed 1 time in two days !! !
different breeds of fish spread by different aquas. I, for example, have three aquas. gold live separately with pterigoplicht brocade and catfish - tarakatum!

Overeating or stale feed in fish may cause an accumulation of gas in the intestines. At the same time, the abdomen swells, they turn over, sometimes they die. You can temporarily raise the water temperature to 26 degrees, increase aeration, sometimes it helps. And remember, a healthy fish is a hungry fish!

How here correctly noticed-contain fish is a whole art, I agree, both in theoretical (most important!) And in practical terms. Diseases of scrofula most often arise from improper care and shitty conditions, nor any neighbors (except all cold-water crucian carpets) should be in the aquarium, and even more aggressive (how have they not yet torn it?) + Good volume with powerful filtration and aeration. And about feeding and it is not necessary to continue, it is easier to kill scarecrows with overfeeding, these fish do not know the measures, therefore they are more often obese.
