How to destroy the snails in the aquarium


How to destroy the snails in the aquarium?

Aquarium snails are beautiful, useful and for the most part do not harm other inhabitants. However, there are times when they breed so abundantly that they begin to annoy the aquarist. This is especially true of soil snails, such as melania. Getting rid of them completely is not very easy, and in the article we will look at the main ways to cope with an excess amount of snails.

A variety of aquarium snails

Snails are gastropods, part of the genus Mollusca, which also includes mussels and mollusks, a feature is a single shell. They move on the surface with one big and muscular leg, eating food in a small mouth. A pair of sensitive tentacles out of the head and on them are located the eyes with which snails explore the world. They have lungs that they breathe on the surface, gills for breathing underwater, or both.

Most of the snails are hermaphroditic, that is, they have both male and female genitals immediately. In most cases, pairing requires a pair, which is to lay eggs, in a mucous protective film, in the aquarium it can often be seen under the leaves of plants. Ampulyaria lay a large number of eggs above the surface of the water, the clutch looks like yellow or orange eggs in a dense, tough pile. Some snails, such as aquarium melania - viviparous. Aquarium snails are omnivores, they can eat algae, food debris, carrion, rotting plant parts. Some large snails can damage tender plants, but contrary to popular belief, small snails do not damage them.

Snails in aquarium

The controlled population of snails does not harm the aquarium, on the contrary, the snails eat the remains of food, clean them of algae, and the ground snails mix and aerate the soil, preventing it from rotting. Many contain interesting snails - ampoules, which are not very demanding and not prone to rapid reproduction. However, small snails, such as fizy and coils tend to multiply rapidly in favorable conditions, and quickly fill the aquarium, covering the glass, filters, plants.

How to avoid snails in the aquarium

Usually, snails enter a new aquarium in the form of caviar or adults, which are transferred along with the plants, decor, or when transplanting fish. Check all plants for snails or their calves, or dip plants in a solution that kills them (Hydra-Tox), even the most attentive aquarists live snails. For a balanced aquarium snails do not pose a threat. Instead of struggling with their penetration into the aquarium, it is better to monitor their number, rapid reproduction means any problems in the aquarium.

Growing snail population in an aquarium

The main reason for the excess number of snails in the aquarium is the abundant feeding of fish. Snails devour food debris and multiply in a square progression. If snails began to disturb you, or rather their number in the aquarium, check if you are overfeeding fish?

Usually the waste accumulates in the ground and serves as a warehouse for snails, so the second task is to siphon the soil and remove the remnants of food. Also, the snails devour algae, and if you do not have antsistrus or similar catfish, you should add them to the jar, creating food competition. In addition, catfish devour the eggs of snails.

Do snails suffer diseases?

Snails are involved in the transmission of diseases among fish populations, as they can be used as carriers for parasites and pathogens. However, you should not worry too much, nevertheless, when buying new types of fish or feeding them with live food, the chance to bring the disease is several times higher.

Fighting snails with chemical methods

New preparations for dealing with snails can be bought in pet stores and online stores, but still they should be used only as a last resort, as it has a lot of side effects. The main problem is that when it works, the massive death of snails will break balance in the aquarium.

Death will cause a bacterial outbreak, changes in water parameters and fish disease. Moreover, chemistry will not kill all the snails, and their eggs, and they will continue to multiply by eating the remnants of their relatives. Carefully read the instructions, some drugs are toxic to fish and shrimp, also avoid using other chemicals for the aquarium, it can reduce effectiveness.

The natural method - snail traps
Snail traps are now produced by many brands, but it’s quite difficult to buy them from us. Easier to do it yourself. The most elementary snail trap - leave a sheet of scalded cabbage at night on the bottom of the aquarium, putting it on the plate. In the morning it will be covered with snails, which are easy to remove. By doing this regularly, you will significantly reduce the population.

If fish, for example, somas do not allow to do so, then you can modernize the method. We take a plastic bottle, close it, burn holes in the bottom, or pierce holes so that the fish cannot get in and the snails easily. Inside we put either lettuce, or cabbage, or other vegetables, better scalded, so they will work more efficiently. Flood the bottle and leave. In the morning you will receive a full bottle of snails.

The natural method is fish
Some fish in nature eat snails, and you can use them to fight. However, if your fish is full enough, it is unlikely to pay attention to them. Keep them slightly hungry. An excellent snail eater is a tetradon, but it has a bad temper and is not suitable for general aquariums. Of the less aggressive - fighting clown, macropod, some types of gourami. Also, all kinds of catfish, eating the eggs of snails. To help the catfish in the fight, turn over the decor, snags, pots, etc., as caviar is most often laid under it.

Natural method - predatory snails
Predatory snails Helena (Antentome helena), carnivores and eat other species of snails. In recent years, they have become quite popular and buy them no problem. These are beautiful, cone-shaped snails, which also look attractive. Grow up to 1.-2 cm. Helena can significantly reduce the number of snails and even completely destroy them, if this happens, they begin to eat like all snails, although such a diet is not typical for them. Although helens do not breed as fast as normal snails, they can give birth to offspring. But the snail is quite expensive, and if it happens at a loss you will not.

Snail myths

Snails pollute the aquarium
On the contrary, aquarium snails eat waste, clean the surface, destroy algae. This myth is most likely to come from the fact that snails thrive in neglected aquariums with abundant feeding and poor maintenance.

Snails can kill small fish
Snails are omnivores and will eat anything they can reach. When the fish dies or is already very weakened, the snails immediately gather for a feast. The aquarist sees that the fish is lying at the bottom and snails are eating it, but they are not to blame for its death. A little thought is easy to understand - a slow-moving snail can pose no danger to healthy and frisky fish.

Snails spoil the plants
Some snails, especially from nature and local water bodies can damage plants. But the bulk of the aquarium snails do not harm the plants in any way. Snails have a small mouth adapted for scraping from surfaces, and higher plants have a hard surface. The origin of the myth is easy to understand - the snails are constantly eating old, dying leaves and it seems that they killed them.

Simple rules:

  • 1. Do not overfeed
  • 2. Clean the soil regularly.
  • 3. Get catfish or shrimp so they eat the same algae
  • 4. Get some snail fish
  • 5. Turn the snags and decor
  • 6. Use snail traps
  • 7. Check out new plants and decor for caviar and snails.
  • 8. Never use plants or decor from local ponds.
  • 9. Do not feed a couple of days of fish, they will be more likely to eat snails
  • 10. Watch out for water if using chemicals.

How to destroy the snails in the aquarium? Wrestling

Snails multiply very quickly and abundantly: in a normal aquarium they have no natural enemies that can control the size of their population. When the snails are no longer able to see the fish, the time comes to get rid of uninvited guests. There are several effective ways to deal with aquarium snails.

The first way is to catch all snails (or at least most of them) manually. It is quite simple, but it will take a lot of time, and there will be several individuals in the ground that can later multiply to the same size.

To spend much less time, you need to put a banana peel or a leaf of lettuce on the bottom of the aquarium. It is preferable to still use the peel, because the salad is often loved to eat fish, thereby reducing the effort to lure snails to a minimum. When all the snails are gathered on the peel, you just need to take it out of the aquarium - but as carefully as possible. This procedure is done repeatedly, otherwise the problem will arise again, how to destroy the snails in the aquarium.

If time permits, it is possible to make natural enemies of these creatures - predatory fish will eat everyone, whatever their number, but there is a danger that they will eat other inhabitants as well, so you need to choose - either old-timers or novices.

A radical method of struggle will be the removal from the aquarium of all its inhabitants and washing the walls with a solution of salt or bleach, as well as boiling the soil. The disadvantage of this method is that the entire internal ecosystem will be destroyed, and it will take a long time until it is restored again. This method can be used for any disease settled in the water - for example, to combine it with the fight against blue-green algae.

The fight against snails in an aquarium can be crowned with success even in the case of buying a special tool in a pet shop, and it must be borne in mind that the means intended to combat snails often contain copper, which is dangerous for fish and plants. After processing, when the snails are dead, it is necessary to get rid of them as soon as possible, because, decomposing, they will pollute the water.

Whichever method of destruction of snails is chosen, it is rather difficult to get rid of them, therefore before planting a couple of cute Ampularia in your aquarium, you need to think carefully about the consequences that can bring a lot of trouble.

How to remove snails from the aquarium

Not all snails are equally useful for aquarium. In spawning aquarium snails do nothing at all, they eat eggs and fish larvae. In the general aquarium of hordes snails can completely destroy aquatic plants. The most common problem for an aquarist is the rapid reproduction of a red corneous coil or red fizzy. They must be periodically disposed of.

The question "Why are cats not a commodity when there are already reviews about them?" - 1 reply

You will need

  • - banana peel;
  • - leaf lettuce;
  • -bleaching powder;
  • - battery 9-12 V;
  • -wire;
  • -copper wire:
  • - fish-predators: macropod ordinary, tetradont and others.


1. You can get rid of snails in several ways. Large snails, such as ampulyaria, can be collected by hand and transferred to another aquarium. The young of these snails are also quite large, and their eggs are under the cover glass of the aquarium. Masonry, like raspberries, is above the water. Remove and discard it.

2. Snails can be caught on the bait. Use banana peel and lettuce leaves as bait. Put the bait on the bottom of the aquarium. When snails are gathered on the bait, they are removed along with the peel or leaves. This procedure must be done several times at intervals of 3-4 days in order to remove not only large snails, but also recently hatched caviar. In this case, it is not necessary to remove fish and plants from the aquarium.

3. There is an electrical method for removing snails. Take 2 stranded copper wires. On one side, clean the ends in the form of panicles by 3-5 cm. Connect the other ends to a battery with a voltage of 9-12 V. Dip the stripped ends into water from opposite sides of the aquarium for 2-3 minutes. Snails die. This method, despite the speed, has its drawbacks. First, many plants do not tolerate copper ions and may die. Secondly, it is not known for certain how this procedure affects fish, although some aquarists claim that it is harmless. Thirdly, dead snails will still have to be removed from the aquarium manually. Decomposing, they will ruin the water.

4. The radical method of dealing with snails is that all fish and plants are removed from the aquarium. Plants destroy. Completely replace the soil or boil it, followed by washing. Disinfect the aquarium with bleach, rinse and dry thoroughly. Refill the aquarium with water. This method can only be used in small aquariums, where biological balance is quickly established and there are no valuable plants.

5. The most effective and environmentally friendly method of dealing with snails is biological. Plant their natural enemies in a snail-infested aquarium. These are hungry adult macropods, large cichlids. The specialized mollusk eaters - tetradonts cope better than others with this task. Caviar snails very well destroy antsistrusy. A pair of spawning cichlase or cancer completely destroys all the snails in a 100-liter aquarium in 2 days.

Helpful advice

Some aquarists specifically populate snails in an aquarium. Before you do this, you need to think about whether you need them and how you are going to deal with them later.

The red coil in the aquarium is a snail that everyone knows

Coils are snails that are suitable for any freshwater aquarium. The shell of their classic shape, and the coil itself is quite beautiful, often it comes in different colors and sizes. They eat algae and food residues that are dangerous to the health of fish. Also, the horn coils serve as a kind of indicator of the quality of water in the aquarium, if they all have risen from the bottom to the surface of the water, it means that there is something wrong with the water and it is time to make substitutions.

About the coils there is a lot of negativity, as they very easily multiply and fill the aquarium. But this happens only if the aquarist is overfeeding the fish and the coils have no natural enemies. How to get rid of extra coils in aquariums can be read by clicking on the link.
They also say that the aquarium coil spoils the plants, but it is not. Simply the coils are often seen on rotting or dead plants and are taken for a reason, and in fact they simply eat up the plant. The coils have too weak teeth that they could gnaw through a hole in the plant, but now they are rotting very much loved and eaten with joy.

Do they carry parasite coils?

It is known that coils can be carriers of parasites during life, which infect and even kill fish. But it is in nature, and in an aquarium the chance with snails to transfer parasites is much lower than with food. Even in frozen food, not to mention live food, various parasites and pathogens can survive.

So I wouldn't worry about that. If it is very important for you to get snails, but you are afraid to bring parasites, then you can bring in the aquarium caviar coils, which is not a carrier.

Facts About Horn Coils

Coils breathe light and forced to rise to the surface of the water for a breath of air. They also carry an air bubble in their sink, which they use as ballast - in order to ascend, or vice versa, quickly sink to the bottom. Coils live for about two years, or even longer.

Most types of coils living in an aquarium grow no larger than a centimeter. They rather well tolerate lightly salted water, which makes them quite good companions for some species of fish. For some fish, for example, tetradons - coil is a favorite food. The fact is that the sink is not very solid and it is quite easy to see it through. The coils are even specially grown to feed the fish, or, on the contrary, they start snail fighters to destroy them in the general aquarium.

Multiplication coils

The coils are hermaphroditic, which means that they also have sexual characteristics of both sexes, but they need a pair for reproduction. In order for the coils in your tank to become a lot, just two snails. It is clear that the more of them initially, the faster they multiply. You just do not need to do anything for this, run it and forget it. They will do everything themselves. Especially quickly the coils flood the aquarium if you overfeed the fish. Feed residues are an excellent nutritional base on which they grow and develop.

But even if you only got one snail, the chances that it will soon be divorced are very high. Do not forget, they are hermaphrodite and can fertilize themselves. Or it can already be fertilized and soon lay eggs. Caviar looks like a transparent drop inside which dots are visible. Caviar of coils can be anywhere, on stones, on the filter, on the walls of the aquarium, even on the shell of other snails. It is covered with a gelatinous composition to protect small snails. Caviar coils peck for 14–30 days depending on water temperature and conditions in the aquarium.
Coils live from one to two years, rarely more. It is often difficult to understand - the coil is already dead or just resting. In that case, you need to ... smell it. У погибшей быстро наступает разложение и сильный запах.No matter how strange it may sound, however, it is important to control the death of snails, especially in small aquariums. The fact is that they can thoroughly spoil the water, as they quickly begin to decompose.

Caviar Coil

Coil content

They prefer warm water, 22-28 C. Coils eat almost everything - vegetables, rotting plants, fodder for fish, dead fish. You can feed vegetables - lettuce, cucumbers, zucchini, cabbage. All this must be boiled for a minute in boiling water and give small pieces.

There is nothing difficult in keeping the coils in the aquarium. Simply start them, they will find food themselves. By the way, very often the snails get into the aquarium together with the plants or the decor on which they lay eggs. So if suddenly you have snails - do not be surprised, it is natural.

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.

Snail Slayer - Helena snail

Freshwater snail Helena (lat. Anentome helena) hails from Southeast Asia, it is often called the predatory snail or traitor snails. Its scientific names are Anentome helena or Clea helena. This separation takes the basis of two genera - Clea (Anentome) for Asian species and Clea (Afrocanidia) for Aficans. The main feature of Helena - it eats other snails, that is, it is ulitkoedom. Than aquarists have learned to use and maintain it to reduce or completely destroy other types of snails in an aquarium.

Habitat in nature

Most Helen like running water, but can live in lakes and ponds, apparently, so they are well adapted to the conditions of the aquarium. In nature, live on sandy or silty substrates.

In nature, helens are predators that feed on live snails and carrion, and this is what made them very popular in the aquarium.
The helen shell is conical, ribbed, the tip of the shell is usually absent. Shell color is yellow, with a dark brown spiral band. The body is gray-green. The maximum shell size is 20 mm, but usually around 15-19 mm. Life expectancy is 1-2 years.

It lives in Indonesia, Thailand, Malaysia.

Content in an aquarium

Helens are very hardy and easy to maintain. Like most other snails, heleans will feel bad in too soft water, as they need minerals for the sink. Although the parameters of water are not too important, it is better to contain medium hard or hard water with a pH of 7-8.

These snails are freshwater and do not need salted water. But they are well tolerated and slightly salted.

The snail Helena is a species that buries itself in the ground, and it requires soft soils, sand or very fine gravel (1-2 mm), for example. This soil should create conditions that are as close to real as possible, since after eating, the helens dig in the soil completely or partially. They will also be more willing to get divorced in an aquarium with soft ground, because after the birth of the young helen fry immediately digs in and then spends most of the time in the ground.

Behavior in the aquarium:


In nature, the diet of helen is carrion, as well as live food - insects and snails. In the aquarium, they eat a large number of snails, for example - nat, coils, melania. However, melania eat the worst. Large snails, such as adult neretins, ampoules, marises, or large types of tilomelia, do not threaten anything. Helena is just not able to cope with them. Helens hunt by thrusting a special tube (at the end of which is an oral opening) into the snail shell and literally sucking it out. And with large snails she can not repeat this trick. Similarly, fish and shrimp, they are too fast for her, and this snail is not suitable for shrimp hunting.

Eating a snail:

If there are not enough snails, they switch to regular feed, they will eat up what's left of feeding aquarium fish. But it is better to feed them additionally, for example, with catfish feed, frozen shrimp, and krill.


Helena breed easily in aquarium conditions, but the number of snails is usually small. Helens are heterosexual snails, not hermaphroditic, and for successful breeding it is necessary to keep a decent amount of snails in order to maximize the chances of breeding heterosexual individuals. Mating is slow and can last for hours. Sometimes other snails join the pair and the whole group of helen sticks together.

The female lays one egg on hard surfaces, stones or snags in the aquarium. The egg develops slowly, and when the young hatch, then falling on the ground immediately buries it and for several months you will not see it.

Approximately the time between the appearance of the egg and the young fry in the aquarium is about 6 months. The young begin to appear openly on reaching a size of about 7-8 mm.
From the hatched snails, a minority live to adulthood. Apparently, the reason is cannibalism, although adult individuals do not touch the young, and to no small degree, in the competition for food during the period of growth in the ground.


As already mentioned, it is dangerous only for small snails. As for the fish, they are completely safe, Helena can attack only the seriously ill fish and finish eating the dead. Shrimps are too fast for this snail, except that molted ones may be at risk. If you contain rare types of shrimp, it is better not to risk and separate them and helen. Like all snails, Helena will eat caviar of fish, if it can get to it. For the fry, it is safe, provided that he is already moving briskly.

According to the observations of aquarists, helens can greatly reduce or even destroy the population of other snails in the aquarium. Since none of the extremes is usually good, your task is to adjust the amount of helen so as to maintain the balance of the species of snails in the aquarium.

How to get rid of small brown snails in an aquarium

-) Wild Yagoda (-

Here are 4 ways to deal with snails.
1. in a saucer or some other vessel in which the hole is made, put the bait pieces of raw potato, dried banana peel, scrapered beef) and put the vessel on the ground at night, in the morning they are taken out together with the gathered clams. the operation is repeated either to a significant decrease in the number of mollusks, or to their complete destruction. In the second case (that is, complete annihilation) after 2 weeks, catching the bait should be repeated to get rid of the young snails hatched from the eggs.
2. You can also use copper sulfate (0.3 g per 10 liters of water. After 3-4 hours, it is necessary to thoroughly clean the aquarium with a complete change of water
(only in the event that at this time there is where to move the inhabitants)
3. Collect mollusks manually (which is quite difficult especially if there are too many of them)
4. Set up if allowed by the population of the aquarium, or Macropod.


Usually it helps only major cleaning - completely wash everything and sanitize. Or use drugs to combat shellfish, for example, "Tetra".
Adult snails can be harvested by putting boiled cabbage leaves, boiled carrots, and a piece of fish into an aquarium. You can put it right in the net or another trap. Snails will gather for food. But if there are at least 2 snails in the aquarium, they have already set aside their eggs. So, soon there will be new snails.
You can also make some species of fish that eat snails (tetradons, many cichlids, boats, macropods and gourami (and other labyrinths too)). But this method is again suitable only for catching adult individuals. Caviar and very small juveniles remain and develop.
Ps. Caviar snails and young snails are easily brought from other people's aquariums. Therefore, buying, for example, algae, maintain quarantine.
