Snails for the aquarium (27 types): description, photos, names, list of all aquarium varieties

Aquarium snails are not just random guests, but full-fledged and very useful inhabitants of the underwater world. They act as tireless cleaners, eating leftover food and cleaning the glass and plant leaves from algae. Watching their unhurried, measured life is incredibly soothing, and the variety of their shapes and colors can surprise even an experienced aquarist.

The world of aquarium snails is vast. It includes both tiny species, barely visible among the plants, and large, impressive specimens that become the center of attention. Some of them prefer to hide in the substrate, others boldly travel throughout the aquarium, and some can even live in brackish water. Each species has its own unique character, habits, and requirements for living conditions.

In this article, we have compiled a list of the 27 most popular and interesting aquarium snails for you. You will find their names, brief descriptions, and photos to help you navigate this diversity. This is your guide to these small but important helpers that can make your aquarium cleaner, more beautiful, and more harmonious.

Snails are useful helpers in the aquarium: they eat food scraps and algae and keep the aquarium clean without causing any trouble. This article lists 27 popular species of aquarium snails with clear descriptions, names, and photos to help you easily choose the right one. There are both easy-to-care-for species for beginners and interesting specimens for experienced enthusiasts. Find out which one is right for your aquarium — calm, clean, and quiet.

General information

Snails are gastropod mollusks that some aquarists specifically breed in home aquariums. These tiny creatures improve the appearance and internal biological balance of the water body. They carry out their activity, based on cleaning the closed water space, naturally and regularly. At the same time, they are distinguished by their unusual appearance and aesthetic appeal. For example, ampullaria, zebra, and tilamellania are spectacular and unusual in appearance.

It is worth mentioning that gastropods are divided into aquatic and terrestrial species according to their lifestyle. Both can be bred, but the conditions for keeping them will be different. Aquatic or aquarium snails feel comfortable in the same body of water as fish that are calm in nature. But they can also get there accidentally – with algae or plants purchased at a pet store, or with soil. Thus, snails and physa snails, which are prone to uncontrolled rapid reproduction and filling of the water space, are bred in aquariums.

Land snails, such as Achatina or grape snails, are bred specifically in separate aquariums.

Snail structure

Aquarium snails have a simple structure—a shell and a body. The shape and size of the shell depends on the species of mollusk. It performs an important function, protecting the internal organs from injury and damage. Outside the shell, there is a foot for movement and a head. On the head, there are a pair of tentacles that serve as organs of touch and eyes. The visual organ is very poorly developed. Aquatic snails breathe with the help of gills, using oxygen dissolved in water. Some species are capable of breathing atmospheric air if they have lungs.

An amazing ability of gastropods is that they can regrow lost body parts!

What role do snails play in an aquarium?

Snails in the aquarium play an important role as cleaners, actively cleaning the water from fish food residues, dead marine life, and decaying vegetation. This rids the water system of toxins and harmful substances that are detrimental to plants and pets, as well as the entire ecosystem as a whole.

Pros and cons of keeping snails

Aquatic mollusks are extremely beneficial for aquariums:

• they rid the space of decomposing toxic substances.
• naturally removes parasitic algae and green film from the walls by feeding on them;
• they filter water, which has a positive effect on its quality.
• they saturate the soil with oxygen by burrowing and turning it over, which prevents the appearance of a musty smell.
• they are an indicator of water quality, rising to the surface when there is a large accumulation of nitrogen.

Aquarium mollusks are a favorite treat for predatory fish, so some aquarists breed gastropods specifically as food for their pets.

Keeping snails in a home aquarium has both advantages and disadvantages. Snails:

• they feed on tender leaves of live plants.
• they eat the eggs of marine creatures.
• secrete large amounts of mucus, which causes the water to become cloudy and foamy;
• change the chemical composition of the water for the worse after they die.

Snails secrete large amounts of mucus, which causes the water to become cloudy and foamy

Uncontrolled reproduction of snails leads to them becoming the masters of the aquarium. The vegetation will be eaten, and the other aquarium inhabitants will not have enough food and oxygen for normal life. Therefore, it is very important to keep the number of mollusks under control and take timely measures when the population increases.

If the number of snails in your aquarium has reached a critical level, we recommend that you familiarize yourself with the means of dealing with snails in an aquarium.

Keeping and caring for aquarium snails

Aquarium gastropods are mostly unpretentious, hardy creatures capable of quickly adapting to the water body in which they live. The following table will help you understand the general picture of keeping and caring for snails:

Water temperature	20-30°C
Hardness	12-28 dGH
Acidity	6.5-8 pH
Aquarium volume	10-80 liters depending on size
Substrate	Fine or coarse sand, soil fraction 1-3 mm
Lighting	Moderate, natural
Feeding	Algae, greens, vegetables; for carnivores – pieces of boiled meat, special protein feed.
Compatibility	With small friendly fish, shrimp

The lifespan of aquatic inhabitants ranges from one to five years. On average, it is three years.

Features of keeping

Water quality is the main requirement for keeping snails. Hard water with a high content of calcium and mineral salts is suitable. These substances are necessary for shell construction. No mollusk, regardless of species, can obtain the necessary amount of calcium from water if it is soft. If there are few mineral salts in the water, the shell becomes thin, deformed, and loses its attractiveness.

Water quality is the main requirement for keeping snails

Warning: under no circumstances should you bring snails from natural water bodies and add them to aquarium inhabitants. There is a high risk of introducing infection!

What to feed

Feeding gastropods is not difficult. They are omnivorous and rarely need additional feeding, with the exception of some species. Snails feed on fish food scraps, decaying animal and plant remains, and algae. However, some slow-moving mollusks do not have time to enjoy their food if they live in the same area as nimble fish that instantly devour their food. Mollusks have only one option left: to feed on live vegetation. In this case, gastropods are fed plant food:

• carrots;
• zucchini and cucumbers;
• lettuce greens.
• cabbage;
• white bread crumbs;

Gastropods are fed plant food

No fish will eat this food, so the mollusks get a lot of useful treats. Some species of snails are carnivorous—they are fed boiled pieces of meat as a supplement.

Types of aquatic snails

Different types of aquatic snails can successfully coexist in a shared aquarium without interfering with each other. Small and large in size, different colors and shades, shapes of shells—all varieties of gastropods are interesting in their own way. Watching them is a pleasure—moving quickly with the help of their feet, snails rapidly climb the walls of the tank, often falling down, but remaining intact thanks to their strong, beautiful shells.

The most popular types of gastropods:

• undemanding, able to live in any body of water – physes, coils, melanies;
• exotic – tilomelania, dragon thorn;
• ampullaria snails are unusual but quite demanding.
• nerites are a huge species of small snails of various colors.
• predators – Helena.

All species of tropical aquarium snails are attractive in appearance, serving as an aesthetic decoration for the home aquascape and a natural part of the aquatic environment.

Ampullaria

The South American snail, which is large and bright yellow in color, is the most popular in aquarium keeping. It has two types of respiration—gill and lung—so it periodically rises to the surface of the water. It gets along well with all friendly fish and shrimp. Due to their large size, ampullaria snails require a lot of free space in the aquarium – at least 10 liters of water per individual.

The large, bright yellow snail is the most popular in aquariums.

Slow-moving ampullaria snails love warm water and are sensitive to oxygen content. If there is a lack of food, they can damage aquarium vegetation. Under suitable conditions, they can live up to 3 years.

Ampullaria mollusks are dioecious. It is almost impossible to determine their sex with certainty, but there are several ways to do so: during mating, the male is on top of the female, which allows you to count the number of males and subsequently control the reproduction process of ampullaria.

Physes

Omnivorous, light brown with olive speckles, fizy are capable of rapid reproduction as hermaphrodites and can completely fill the water space. They often end up as accidental aquarium pets, arriving with soil or plants. Physa snails are 10-15 mm in size. Despite their small size, they secrete large amounts of mucus, which has a detrimental effect on the biological balance. Controlled maintenance of physids in a home aquarium is quite justified, because they:

• destroy green film on the glass;
• they feed on detritus.
• they combat the film on the water surface, increasing oxygen penetration.

Physids will not survive in a tank with cichlids, tetradons, and other predatory fish.

Omnivorous, light brown with olive speckles, these snails are capable of rapid reproduction.

Helena

A predatory snail with a cone-shaped shell of yellow background with transverse brown stripes. It feeds exclusively on protein food, but is harmless to large gastropods, fish, and vegetation. Small snails such as hizi, katuki, and melania will not survive in the same tank as Helena.

The striped snail looks impressive in an aquarium and is not capable of uncontrolled reproduction, as individuals of different sexes are required for spawning. Helena is unpretentious, but quite demanding in terms of water hardness, which should be at least 9-12 units. This tropical inhabitant feels comfortable in water at a temperature of 22-23 degrees.

Melania

Miniature melania snails do not exceed 3.5 cm in length and are famous for their rapid reproduction rates. They are rarely bred specifically; most often, melania snails appear in aquariums along with soil and purchased algae. The shell of the mollusk is elongated, cone-shaped, with several turns.

Most of the time, melania snails sit buried in the ground. As the population increases, the ground becomes alive, as if moving. In this case, it becomes impossible to get rid of the snails without restarting the aquarium. But they do have one advantage: they are unpretentious creatures that can thrive and develop in water bodies with any water parameters.

Coils

The simplest gastropods, capable of accidentally appearing in any domestic water body. Coils differ from other species in the shape of their shell, which is twisted into a spiral in the form of a ram's horn. The color of the shell ranges from brown to reddish-brown. The size of the snail does not exceed 3 cm. Interestingly, snails like to float on the water surface with their shell facing down.

Aquarists have mixed feelings about these mollusks. On the one hand, they are valued for eating algae and cleaning glass, as well as for their attractive appearance, but on the other hand, they are constantly fighting them when their population increases. To prevent the uncontrolled reproduction of snails in aquariums, predatory fish and Helena snails are kept.

Coils can provide a timely signal of high nitrogen concentration in the water. They float to the surface without sinking to the bottom of the tank.

Neretina

Aquarists love striking nerites for their striped shells in rich colors with contrasting spots. They are excellent aquarium cleaners, feeding on algae without touching live plants. Although undemanding in terms of care, nerites are sensitive to high nitrogen levels in the water and sudden temperature changes. They get along well with peaceful fish. These mollusks are bred in salt water.

Undemanding in terms of maintenance, neretina are nevertheless sensitive to high levels of nitrogen in the water.

Bitinia

Excellent water purifiers, capable of cleaning the space not only of algae and food residues, but also of bacteria and fungi. These small creatures with brown shells twisted into several spirals are only demanding when it comes to water purity. Bittinia easily penetrate the most inaccessible places, disinfecting the aquarium space. It is not difficult to distinguish between the sexes—males are smaller and lighter in color than females. The tiny eggs are laid on the surface of leaves and stems.

Warning: Bithynia are often carriers of parasitic worms!

Luzhanka

The light brown color of the shells of horned snails with dark greenish stripes changes as they mature. The shell is equipped with a lid that closes when the mollusk hides inside. Snails feed on plant food, food debris, and damaged plants. They actively stir the soil, saturating it with oxygen. They are quite demanding in terms of water purity and oxygen content.

Hercules

An attractive, unusually shaped snail that resembles a pagoda. It has the same golden-brown shell, twisted in a spiral with small spikes all over its surface. But compared to a pagoda, it is impressive in size, which is why it is nicknamed Hercules. The mollusk is dioecious, peaceful, and voracious. To protect higher plants from being eaten, Hercules must be fed.

Horned

In nature, it inhabits vegetation-rich water bodies on the island of Sumatra.

Gourami

Marble

Gourami

The marble gourami is a mutation of the blue gourami. It is a large fish. Individuals of the marble gourami species can reach a length of 13 cm. The body is oval, tall, and compressed from the sides. The pelvic fins are long and thread-like. The anal fin is wide. The body is marbled: dark gray spots of irregular shape are located on a light gray background. The anal, dorsal, and caudal fins are dark gray with numerous yellow spots. The pectoral fins are transparent and colorless. The male differs from the female in that it has a narrower body, bright coloration, and elongated, more pointed dorsal and anal fins. It is best kept in an aquarium with a volume of 50 liters or more.

Golden

Sphaerichthys osphromenoides

Chocolate gouramis are found in Indonesia (Sumatra, Borneo) and Malaysia. Blue gouramis are very peaceful and get along well with various species of large and small fish, but sometimes there are individuals that show aggression towards their fellow species. They are diurnal and stay in the middle and upper layers of the water. These fish are very interesting to watch: they are cheerful and never miss an opportunity to frolic, curious about everything new, whether it be a decorative element or another fish.

The shell is golden, yellow, or bright brown in color. It grows to 2-3 cm in length. The corbicula is considered an excellent aquarium cleaner, actively filtering the water. The water temperature for it should be 20-28 degrees, with a hardness of 10-22. The mollusk does not tolerate high nitrogen content in the water.

This interesting-looking snail with a bivalve shell is a viviparous hermaphrodite.

Spixi

Spixi are somewhat similar in appearance to ampullaria, but are smaller in size – up to 3 cm, and do not have a breathing tube. Their yellow or white shell is decorated with a dark thin stripe that spirals around. Unlike the slow-moving ampullaria, spixi move extremely quickly. During the day, they usually rest, burrowing into the ground, and at night they feed on algae and decaying plant remains.

Black mystery

Black, with golden or olive-colored speckles, the striking shell of these snails can be a real decoration for your home pond. Even the foot of the mystery snail is colored dark purple or black. This unusual-looking snail also has an unusual body structure—it has a siphon that allows it to breathe atmospheric air.

The mollusks are dioecious, producing 300 to 700 eggs per clutch. Mystery snails are friendly and peaceful by nature and get along well with other aquarium pets. If food is scarce, they can feed on young plants.

Pagoda

Freshwater snails are distinguished by their bizarre, unusual shape and multi-level shell, which is yellow-brown or gray in color. The pagoda's shell is decorated with peculiar spikes located on several levels of coils. The mollusk feeds on plant food. It is a viviparous creature, whose young often die and do not reach maturity. The pagoda is 3-6 cm in size. The recommended water temperature is 23-26 degrees, hardness 8-20.

Pagoda size: 3-6 cm

Green torpedo

These unpretentious little torpedoes with beautiful gray-green or olive shells get along perfectly with other aquarium pets. They are active at night, feeding on food scraps and dead vegetation. The water temperature for keeping green torpedoes should be 18-26 degrees, with a hardness of 8 to 20. Torpedoes are dioecious mollusks, with males being larger and brighter than females. After mating, larvae appear, which grow very slowly, preventing the snails from rapidly filling the aquarium.

The water temperature for keeping a green torpedo should be 18-26 degrees.

Tiara

With its interesting shape and appearance, the tiara will not go unnoticed in a home aquarium. Thin needles are located across the entire surface of the light brown spiral shell. The tiara grows up to 3 cm and is active at night. It feeds on animal and plant debris and does not touch live vegetation. The mollusk is dioecious and requires salt water for spawning. The water temperature for tiaras should be 22-26 degrees, with medium hardness.

Tilamellania

Large tilamelenia can decorate any aquascape. They grow up to 10-12 cm in length and are distinguished by their elongated cone-shaped shell, completely covered with small spines. Their brown or reddish-brown shell looks impressive against the background of their bright orange or yellow body.

It is an omnivorous creature with a remarkable appetite, which is why it requires additional feeding with animal and plant food. Tilamelia is nocturnal. It is viviparous. One female can carry no more than two eggs at a time. Peaceful fish and shrimp are excellent neighbors.

Tilamelia is nocturnal.

Theodoxus

Theodoxus snails are distinguished by their variety of colors. Their shells can be dark or light gray, beige, brown, or limestone. But they always have various markings—spots, patterns, zigzags—which give the mollusk an extraordinary appeal. Theodoxus look very exotic and have a very strong shell, as in natural conditions they live in water bodies with strong currents. They grow no more than 2 cm in length and lay eggs on hard surfaces. The larvae grow very slowly. The required water temperature is 24-25 degrees.

They grow to a maximum length of 2 cm.

River mussel

The river mussel is famous for its slowness—it crawls no more than 8-10 cm per night! Bivalves have a variety of shell colors, with yellow, blue, and green shades predominating. The Dreissenid group can beautifully decorate the underwater kingdom and clean it of decaying remains. It grows up to 4-5 cm in length. The required water temperature is 24-26 degrees.

Zebra

The zebra is a variety of nerite with a striped shell in dark brown and yellow stripes. These miniature creatures feed on algae and are excellent at cleaning aquarium glass from green and yellow deposits. They live for 2-3 years in domestic conditions. Zebras tend to escape from captivity, so it is advisable to periodically cover the tank with a lid. They look very exotic and unusual in the water.

Black-horned (Batman)

Small, no more than 2.5 cm in length, Batman is an excellent cleaner of aquatic space. It does not touch living plants, but actively destroys animal and plant debris. The body of the black-horned snail is colored in dark tones – black or dark gray. It looks spectacular against the background of light soil and delicate green vegetation. It prefers water with a temperature of 22 to 28 degrees and a hardness level of 10 to 30.

Batman is an excellent cleaner of aquatic environments.

To breed Batman, you will need a spawning aquarium with salt water, numerous shelters, and decorations. Females lay eggs only on hard surfaces.

Types of land snails

Not all gastropods live in water. Land snails are no less interesting to keep at home and are undemanding in terms of living conditions. There are many species of land snails in nature, but only two species are suitable for keeping in home aquariums: Achatina and grape snails, which will be discussed below.

A terrarium is set up for land snails to live in, which can be a regular aquarium without water or even a plastic food container. Soil is a must in the terrarium, as these creatures love to burrow into it. It must be moistened regularly to ensure optimal humidity in the house. Their diet is plant-based – vegetables, fruits, greens. However, protein-rich food is used for feeding, without which the mollusks will not form a strong, beautiful shell.

Giant Achatina

This is a large representative of gastropods, capable of reaching a length of 15-18 cm with a shell diameter of 25-30 cm. An African snail with intelligence, capable of remembering and recognizing its owner. The color of the Achatina's shell is yellowish-brown or cream with numerous dark patterns across its smooth, shiny surface. The shell is cone-shaped. The color of the animal depends entirely on the subspecies. For example, there are lemon, tiger, and other varieties of Achatina.

Achatina snail eggs are white and oval-shaped. The number of eggs increases with each subsequent clutch. It is strongly recommended not to touch the clutch with your hands, otherwise the embryos may die.

Exotic giants are becoming increasingly popular with aquarists around the world.

Grape

This small land snail is striking in its regular shape and charming appearance. The diameter of its shell does not exceed 4.5 cm, and its color is beige to yellowish-brown. The grape snail feeds on plant food. It prefers a humid climate and hides in the shade of foliage or under rocks during droughts.

Which snails should you not keep?

Not all snails are beneficial to an aquarium. When choosing a species of gastropod, many factors must be taken into account. For example, some of them actively eat live plants, despite the abundance of other food. Others like to feast on fish roe. If the goal is to breed fish, then it makes no sense to keep snails that feed on roe. Often, natural mollusks that are carriers of infectious diseases and parasites are sold in markets under the guise of aquarium mollusks.

Therefore, before making a choice, you need to carefully study the characteristics, nature, and conditions of keeping each specific species of gastropod, and only then go to the store to make a purchase. It is imperative to consider the habitat requirements of your future pets and compare them with the existing conditions of your home aquarium.

Beginning aquarists are better off sticking to one species of snail. Large individuals often bully smaller representatives of other species and may even eat them!

Snail reproduction

Favorable living conditions allow snails to reproduce without any difficulties. Mating proceeds without problems, after which females lay eggs on hard surfaces—rocks, decorative elements, aquarium glass, or plant leaves. After a while, larvae appear. In a general aquarium, the young have little chance of survival. If the goal is specifically to breed snails, it is better to do so in a separately equipped tank.

Favorable living conditions allow snails to reproduce without any difficulties.

How snails reproduce

Mollusks reproduce in different ways, depending on whether they are dioecious or hermaphroditic. In the first case, individuals of different sexes are required to produce offspring, while in the second case, the reproduction process occurs even in a single individual. Hermaphrodites are usually invasive snails that accidentally enter a domestic pond, hiding as larvae in purchased soil or algae. These include physa, melania, and catfish.

The methods of reproduction also differ among different mollusks. Some snails develop their offspring inside their own bodies, while others attach capsules with eggs or roe to plants and stones. The eggs are so small that they are invisible to the naked eye. Therefore, the number of mollusks often increases rapidly without the owner's knowledge.

General breeding rules

The basic rules for keeping and breeding snails are:

• maintaining a stable optimal water temperature – sudden changes can be detrimental to the health of your pets;
• choosing the “right” neighbors – invertebrates cannot be kept together with cichlids, tetras, many labyrinth fish that swallow shells, and ancyrists that eat gastropod eggs;
• breeding valuable species of mollusks in a separate aquarium and transferring grown fry to a common tank;
• regular feeding with food high in calcium (for example, grated eggshells).

Valuable species of mollusks are bred in a separate aquarium

When breeding hermaphroditic snails, it is important to control their numbers. It is necessary to periodically check carefully for the presence of eggs and larvae under the substrate or vegetation until the number of individuals has increased so much that you have to restart the aquarium.

Do not keep snails in a herbarium. Even with additional feeding, they will harm the plants and have a negative impact on the appearance of the aquascape!

As you can see, the world of aquarium snails is incredibly diverse. From tiny physa and catfish to spectacular ampullaria and nerites, each species brings its own flavor to the underwater world. They can become not only living decorations, but also hard-working helpers who keep your glass home clean.

When choosing pets, it is important to remember about balance. Some snails, such as helenas, will help control the population of other mollusks, while melanias, for example, will quietly loosen the soil. The main thing is to consider their needs and compatibility with other inhabitants of the aquarium.

We hope this overview will help you navigate the variety of species and make an informed choice. Properly selected snails will become valuable and interesting inhabitants of your aquarium, whose lives you can observe endlessly.
