Snails are present in almost any aquarium. And not always the owner acquires these mollusks consciously. Most of them appear completely unexpected, getting into the aquarium with plants, soil or water. What are aquarium snails for?

The question "Plots turtles." - 3 replies


1. Any aquarium needs constant cleaning of walls, stones and various shelters from plaque appearing on its walls. It is also necessary to clean the soil from the remnants of food, fish excrement, and rotten parts of aquarium plants. This task is very successfully cope aquarium snails.
In addition, snails are a kind of indicator of contamination of the aquarium. For example, too many of these acroluxes indicate a good feed base. Therefore, it is likely that you regularly overfeed fish, and uneaten food will sink to the bottom.

2. Small aquarium snails, as well as their caviar serves as a treat for fish. Shellfish, like plants, help to maintain stability in a closed biological aquarium system.
Some types of mollusks - for example, melania, which are one of the most popular types of aquarium snails - constantly loosen and drain the ground. This prevents the development of anaerobic zones and, as a result, prevents the formation of hydrogen sulfide. Melanias do not have lungs - they breathe through the gills. If the water of your aquarium, and therefore in its soil, begins to feel a lack of oxygen, the snails feel it first, even before the amount of harmful substances that is dangerous for fish.
If you notice that your melania left the ground and crawl along the walls of the aquarium - it's time to take drastic measures. It is necessary to change the water and enhance its filtration and aeration, to siphon the soil.

3. The presence of different types of snails will give a special flavor to your aquarium. Thinking through his design do not forget about these mollusks.
However, it should be remembered that aquarium snails have the ability to multiply very quickly. With a lack of food, mollusks can begin to eat young plants. Also, overcrowding can cause the problem of lack of oxygen in the water. Therefore, the number of snails must be kept under control.

Tip 2: What are snails in the aquarium

Decorative snails are quite common inhabitants of the aquarium. They decorate it well and help to relax after a hard day: their elegant slowness captivates many. In addition to aesthetics and beauty, these mollusks also have a practical function.

Snails can bring both harm and benefit to the aquarium ecosystem. It all depends on their variety and quantity. Such species of mollusks as ampulyaria, horn coil, acrolux, melania are very popular with aquarists. If you properly care for the aquarium and control the number of snails, they will bring a lot of benefit. Shellfish are excellent aquarium nurses. They not only eat up food that fish did not eat, but also their excrement. Thus, these aquatic inhabitants contribute to the purification of water. The remains of feed are a favorable environment for the growth of pathogenic bacteria, which can make turbid of clear water in a matter of hours. In addition, mollusks eat dead plant parts and clean their bacterial deposits from the walls with their rough tongue. This affects the installation of a favorable microclimate and biological equilibrium in aquarium. Certain types of mollusks, such as ampulyarias, serve as a kind of indicator of the status of aquarium water. By their behavior, one can determine if there is enough oxygen in the water. With its shortage, as well as with a sharp change in the pH of the water, the ampoule rises through the glass to the surface of the water and pulls out its siphon tube, the organ that allows it to breathe air. Similarly, the snail "signals" to an inexperienced aquarist that it is time to make a water change or get a good aerator. One of the disadvantages of ornamental snails is their active reproduction. A large number of mollusks in aquarium can lead to overcrowding and, as a result, a lack of oxygen to other inhabitants. In addition, a large population of snails can greatly eat the plants. The best ratio can be considered: one snail per 10 liters of water. Therefore, in a timely manner, scrape their eggs from the glasses, which they lay off with an enviable constancy, to prevent overcrowding of the aquarium. Will they live in your aquarium snailsOr not - it's up to you. But remember that you can not put mollusks in it from the reservoirs, because with them can get an infection. In addition, some pond snails produce mucus in the water that pollutes it. Purchase mollusks for your aquarium only in pet stores.

Snails in the aquarium: the benefits and harm, description of species

Aquarium snails - the eternal companions of fish, they live in all types of aquariums, sometimes even where it seems impossible. We have described in some detail the most common snails in our articles. But, we will try to collect brief information on all the described species, and then the readers will already choose what interests them.


If you have ever had an aquarium, then you must have come across aquarium snails. All types of aquarium snails are often viewed as something that appears in one night, covers plants, muddies water and ruins fish. Sometimes, they do some of this, but the benefits of snails in an aquarium are much greater. Many species of aquarium snails eat leftover food and other garbage, some clean the glass and decor, and some are simply very beautiful.

To avoid problems with snails in an aquarium, you just need to understand what causes their rapid growth, and which species do not suit you. In this article, we will briefly describe the most popular types of aquarium snails, but if you want to learn more about any of them, then we have already written about almost every species, and you will find a description by clicking on the links in the article.

The role of snails in the aquarium

What feed aquarium snails? Although the type of food depends on the specific type of snail, most of them are omnivores, they eat everything they can find. Usually snails eat rotting plants, dead fish, food debris and various algae. In this way, they serve the aquarist - cleaning the aquarium from excess food residue, thereby maintaining cleanliness and lowering the level of toxins in the water.
Of course, different types of snails have disadvantages. The most common problem is that some species can spoil and even eat plants to the ground. In addition, all the snails will eat fish eggs, if they can get to it and should not keep them in spawning.
The most frequent problem is that there are too many of them. We have already discussed this question in detail in the article - how to get rid of snails in an aquarium. There are listed both the ways and causes of violent reproduction.
So, most often contain:

The coil is generally a classic snail, it can be found in almost any aquarium. It does not have any particular features, its small size, ease of reproduction and an interesting appearance have made it quite popular. It is useful in moderation, does not cause excessive harm, only it spoils the appearance of the aquarium.

Ampulyaria is also quite common, but unlike coils, it is already quite demanding on the content. Since ampoules are one of the largest species of aquarium snails, they have a corresponding appetite. Can damage young and delicate plants with a lack of food. The rest is beautiful, big, interesting.

Tilomelania - rapidly growing popularity of aquarium snails. But, besides the fact that tilomeleanii very beautiful, they are also very demanding on the conditions of detention. They can rather be attributed to the exotic, which must be kept separately, and well cared for, than to simple species.

Melania - are common as coils, but differ from them not only in appearance, but also in lifestyle. Melania live in the ground, breed in the same place, which is beneficial to the aquarium, as they mix it. But, they are prone to rapid growth, and getting rid of them is not so easy.

Neretina is a beautiful and very useful snail. Quite small, about 2 cm, neretina perfectly clean the aquarium from algae. I advise you to follow the link and watch the video as it happens. Among the shortcomings - the price and a short lifespan, about a year.

Three types of neretin

Marisa is a real monster that can grow up to 6 cm or more. Large and very voracious, the marisa is not very suitable for general aquariums, as it eats away the plants at the root.

Helena is one of the most unusual species. The fact is that they eat ... other snails. If you have a lot of snails, then Helena is one of the ways to get rid of them. Details about the content of Helen on the link.

Fiza is also a very common snail. Small, easily propagated, lives in very harsh conditions. Among the shortcomings, it can gnaw through holes in the leaves of rather hard plants, such as echinodorus. What spoils their appearance, so if you are a fan of plants, then it is better to get rid of nat.

Snails to be avoided

Of those that are listed above - there are none. Anyway, the main types of snails are completely harmless. But, very often in the markets they sell under the guise of aquarium snails, species that live in the natural waters of our latitudes. Prudovik, lawn, perlovitsa and other species. The fact is that they not only eat plants (often at the root), but also carry disease and parasites. And just to become a victim of fraud is very unpleasant. How to understand that these are local snails? View on the Internet the main types of snails and not buy those that do not apply to them.


Almost all types of aquarium snails are good inhabitants, only for some people need their own conditions, which are not suitable for a common aquarium. They become a problem only if something goes wrong in the aquarium, and even then this is not a problem - this is a signal. We have listed aspen species of snails that are kept in an aquarium, and in other articles have told about them in more detail. Read, think, choose.

Fish and snails: enemies or friends?

Fish and snails: enemies or friends?

The relevance of the gastronomic symbiosis of these aquarium dwellers is not so interesting for experienced aquarists, who will say with complete confidence: "Well, what’s not clear here! Fish eat snails, and snails eat dead fish ... that's all." Nevertheless, these processes are incomprehensible to a beginner or a young aquarist. And sometimes, when he sees how ampulyaria "sticks" in a dead fish, he enters into a kind of stupor with the question - what to do with it?

Drop the lyrics and get down to business!

First, let's make a reservation that the aquarium with snails certainly looks more natural and beautiful. But without them, you can safely do. Aquarium snails are sanitation workers of the aquarium (they clean the walls, decor, plants, etc.), but at the same time they need tougher water (due to the need to obtain building material for the sink). There are relatively capricious snails (Ampularia), there are as many-Tatar Igo - tenacious and all-seizing (Coils). In general, there are advantages and I would say not flaws, but nuances.

Now let's highlight the question: do snails eat fish, can they do it at all!

All snails are scavengers, gently called them "aquarium attendants" - but this does not change the essence. As soon as the aquarium fish has died, and sometimes, even when it flutters, the "crowd" of snails attacks the lifeless body. Thus, it is a natural process envisioned by mother nature, and you should not be afraid of it. Another question is what to do with it? Dead fish, and even more dead fish from an illness, need to be removed from the aquarium without waiting for the end of the feast. Otherwise, you risk spreading the infection throughout the aquarium.

Live and healthy aquarium fish, snails will not eat! For this to happen snails need a pair of jet engines.

In turn, the fish do not remain in debt! Many aquarium fish are not averse to eat snails, for some it is an exquisite delicacy, for example, gouramimany cichlidsfamily GOLD FISH and even shrimp not averse to taste grated snails.

So, if you see that your ampoule is taken out, it is better to drop it or return it to the store. She will not be allowed to live anyway.

It is worth noting that many aquarists, on the contrary, breed snails (Coils) to feed the fish, thereby saving on food, introducing diversity in the diet and at the same time knowing that live food is not contagious.

Are snails needed in an aquarium?

Oleg Pudovkin

In my opinion - still needed, if the aquarium with fish.
And now about the different types of personal experience:
one). Ampouleria Large, we can say that beautiful.
Pluses: completely eat up the fish, not eaten by fish, from the bottom. Seduce from the film on the surface and from the mucus on the slit filters and decorations. Sometimes I have noticed when eating fish excrement. When the mustache is straightened (if they are allowed to fish), they will smith smartly. Looking for Nivi is interesting - as they dive from top to bottom.
Cons: eat (and crap) a lot and with hunger can nadkuskivyvat plants. In my opinion on 30l one ampule is enough. It was in the otsadnik that I decided to otsadit my only Ampularia - sorry for expensive plants.
2). Coils. At first about minuses. Many sources say that they multiply nemeryanno and that then it is difficult to get rid of them. The fruit is really nehilo, but only in an aquarium with fry (without large fish and catfish). Mine, while they were in the minder were bred at great speed. I already began to regret that I accidentally brought these creatures to me. BUT when I witnessed that (this is already a plus), the coils of lemongrass bush (thrown by me into the trap) were completely cleaned about black growths on coils for 1 day, I changed my mind about getting rid of them, but on the contrary - I threw 6 pieces into the main tank. In this aquas, they are no longer prolific as fast as they are (probably a couple of Ancistrus catfish do not allow it). Now there are no more than 15 pcs. Do not strain at all. Another drawback - if the aquarium glass is overgrown with algae, then the coils really (as Irina writes) paint patterns on the glass. Not very nice looking. If there are still a lot of them, then they can be fished, crushed shells and fed to fish. Good live free feed own breeding. Another advantages: the coils practically do not penetrate the plants and (like ampoules), they eat up the food well from the bottom.
3). Neretina. Very beautiful. They clean the glass better than others and not with patterns, but the entire area. Eat little. Plants do not gnaw at all. Minus - do not breed in captivity and cost from 40 to 100 rubles / pcs. I have 3 of them in 90 liters.
four). Melania. He did not dare to start. They say that they loosen the ground - so I siphon him so well. But if they are very fertile, the ground will be like a living, stirring creature. And it is much harder to remove them than coils.

Elena Borey

Of course. They clean the plants, eat up the fish, destroy the bacterial film on the surface of the water. In no case can not be placed in an aquarium snails from an open pond, they are carriers of diseases.

Irina Volvenko

To clean the walls - loudly said. They will leave fancy patterns on overgrown glass ... You need to clean it with a scraper, you can use a sponge or a net. But for the disposal of excess feed snails are very useful. And as an additional forage, masonry and juveniles will fit. Very useful for aquarium-snails that live in the ground. They mix it up, loosen it. Eat detritus. And if conditions abruptly change in an aquarium, they climb up the glass as if on cue. A signal to the host is given to take action.

Why do we need snails in the aquarium if there is a catfish?

Elena Grigorieva

Once I changed aqua, otsadila snails per day in a separate jar. When I saw how much they had spoiled for a day (they don’t have to eat so many fish products) I refused them forever. So, I don’t know how anyone, but I don’t need them for nothing. My aqua 200 liters, catfish clean the glass and eat up the remnants of food, and water and glass are clean.

Katyusha Boyko

I'm not special, but I think that snails are needed, as far as I know, seaweed snails do not eat, they feed on fish excrements and food remains. Get 3-5 snails, preferably large ones, in the future they will multiply under favorable conditions, and besides, the snails look beautiful in the aquarium)))
Good luck)))


First, they turn excess feed into excreta, which are easily decomposed and then either absorbed by the plants or removed by the filter (otherwise the water in the aquarium rots). Secondly, many aquarists use crushed snails as food for large fish, and in ground form - for small fish. Snails do not eat fish excrement))) like catfish)))

Snails - clean the plants ...
Аквариумисты часто задаются вопросом: что же такое улитки в аквариуме - благо или наказание? Несомненно одно - в нерестовике с икрой им места нет. Для голодных улиток (а они почти всегда голодны) лишь немногие виды корма являются таким же деликатесом, как свежая икра. And if the snails would satisfy their hunger, after eating several eggs entirely, it is not so, apparently, for them the greatest pleasure is the destruction of the shells of all the eggs that can be reached.
At the same time, the snails are not only able to do very useful work in the nursery aquarium, but actually do it. Sometimes it is difficult for an aquarist to determine how much food his growing pets need. If they are undernourished, the fry lag far behind in growth and are unlikely to become large healthy fish. If, however, to give food in abundance, a much more serious, unavoidable catastrophe is inevitable: the water will rot and most of the fry will die. In the presence of snails, successfully coping with excess feed, the danger of overfeeding fish is greatly minimized.
Snails are often blamed for the fact that they excrete more excrement than they eat. However, to expect that they will destroy the fish excrement is just as stupid as hoping in this regard for catfish. Both those and others perfectly clean the aquarium from the remnants of food, but do not feed them with fish excrement!
Until the 20s of our century, some snails were considered necessary, desirable inhabitants of a "balanced" aquarium. Theoretically, this provision was justified as follows; fish excrement supports the existence of snails, and excretions of snails themselves are a source of nitrogen for plants, which, in turn, release oxygen instead of consumed by fish. A similar theory prevailed for many years, but in the end it was possible to prove that in an aquarium without plants there is as much oxygen as in a heavily landscaped one, and that in the dark plants compete with fish for oxygen, absorbing it.
So, what are the functions of snails in an aquarium? A good filter, forcing water to circulate, helps to maintain optimum oxygen content and purity in it, removing dirt from the water. Then why are snails needed then? However, firstly, they convert excess feed into excreta, which are easily decomposed and then either absorbed by plants or removed by a filter. Secondly, many aquarists use crushed snails as food for large fish, and in ground form - for small fish ...

Snails are not required. It all depends on your desire to acquire or not. Small snails, if their numbers are not controlled, will very soon become a scourge in the aquarium — they multiply very quickly and begin to eat. Aquarium plants. Yes, and Ampulyaria is not averse to them regale. It is possible, in addition to Platydoras, to start another catfish sticking to it - Ancistrus or Gastromizon.

A lot of snails are bred in the aquarium. Is it bad for fish? Or what is the use of them?

Dj t'emmy

for fish it is not harmful, it is even useful, they clean the walls of the aquarium, and sometimes they eat waste from the bottom, it can not interfere with the fish, the only thing when they become very, very much, they will take up more space, and the fish will have less space to get , well, if the aquarium is more than 100 liters, then it even can not be a problem! For example, I was happy when I had a lot of snails!) If it really worries, then give it to friends)

Marishka Latushkina

When it is too much, it is bad, but with their growth you can adjust it like this: chop a piece of cucumber or zucchini on a fork and drop it into the aquarium, when the snails stick around the cucumber, take out the fork, shake off the snails and drop it in the aqua again. etc.
