The ratio of fans of the water world to the snails is ambiguous. Some see them as a kind of natural habitat, others – pin their hopes on cleaning the walls of the aquarium from plaque and rotten leaves.
For the third, an interesting and harmless way of life is important. Who are they, these not asked guests?
Since childhood, everybody knows riddles about creatures that carry their home on themselves and hide in it at the slightest danger. This is a snail. Slow-moving creatures that do not harm anyone and have a good ability to adapt to external conditions.
These characteristics are also suitable for the aquatic inhabitant of the aquarium – the cochlea.

It looks like a small wrapped shell, whose color can change several times over a short, two-year life (from dark brown to bright red).
The snail itself has almost the same color, climbs out from the shelter when it is confident in its safety. On her head are a pair of tender horns that perform the functions of a tactile organ.
At the base of the horns there are tiny beady eyes. The name of the gastropod class itself explains their appearance. On the body there is one leg, the size of which is almost equal to the body.
With this foot, the snail moves along the bottom.
However, there is another, very interesting way to move it. It is due to the possibility of placing in the shell, except for the body of the cochlea, an air bubble.
With it, the snail floats to the surface of the aquarium and can easily move along the horizontal plane inside it. At any time when the coil senses danger, it blows this air bubble out, and under its own weight quickly sinks to the bottom.
At the same time, she almost completely hides in the house and becomes invisible to others.
The size of such an interesting resident is small – no more than 3-3.5 cm in diameter. However, a pattern has been observed: the more individuals appear in a unit of volume, the smaller they become.
Special requirements for the world around the coils are not characterized. Despite the fact that in nature they safely live in polluted reservoirs with standing water of different temperatures, having adapted to indoor aquariums, for them the optimum water temperature within 22-28 ° C has become, without additional aerations and filtrations.
The low requirement for water saturation with oxygen is also due to the fact that the coils can breathe oxygen from the air. Periodically they float to the surface and swallow it from above the aquarium space.
Love snail water calm, not moving. Crawl freely on the bottom or walls of the aquarium, picking up the remnants of food and dead rotten leaves.
The soil does not break in, to the roots of plants show indifference. Live in the bottom space, if we exclude surfacing to the top.
Omnivorous and harmless. Not hunters, not capable of aggression, easy to get along with small peace-loving fish.
The calm character is manifested from the moment it enters the aquarium. Sometimes it is invisible.
The aquarist himself sometimes wonders how his aquarium was filled with so many small guests? And they can get in the form of small newborn snails, stuck in the roots of transplanted plants or together with a substitute soil.
Breed quickly and easily, especially if a lot of food. Diligent care for them is not necessary.
Looks at their brightly colored or spotted house on the background of green algae beautiful and a little mysterious.
Despite the apparent sameness, one can distinguish several varieties of them:
- Horn coil
Horn coil (gray-brown, sometimes with divorces or darker area on top);
Far Eastern coil
The coil is Far Eastern (it has oblique lines on the shell). The homeland of the mollusk is East Asia. Feature: likes to eat plants, although rarely eats fresh shoots;
keeled snail (the most frequent uninvited guest). It has a flat shape, the diameter is larger than the height;
Wrapped (it stands out for its dirty yellow color, with intensive reproduction pollutes the water of the aquarium);
Red Many people prefer to settle them in an aquarium, due to the properties to clean the aquarium from the remains of food that have settled to the bottom of the aquarium and the beautiful red color.
In the photo you can see such reel inhabitants of the aquarium. They look different, but the appearance does not affect the behavior.
They are able to live and multiply in the same way, identical in content.
The snail coil has a negative trait: it is capable of carrying diseases and parasites. Therefore, many experienced aquarists are wary of them, especially if the place where algae are purchased is not verified.
Pests such as black beard are often carried with snails. The shell can become completely overgrown with black soft hairs and become practically a lump of such a pest.
Unlike aquarium fish for breeding coils does not require the creation of special conditions. This is due to the fact that it is a hermaphrodite, that is, one individual combines the characteristics of both sexes.
Therefore, starting from one individual, you can get a whole team of small inhabitants of the aquarium with their own houses behind them.
The intensity of reproduction will depend on the amount of remaining feed and the presence of fish species for which they can become prey (for example, antsistrus).
Snail caviar looks like a clot of colorless transparent microbubbles, very dense in consistency. They lay its adult female individuals on the leaves of plants, from their reverse side.
Sometimes it uses the wall of the aquarium or the interior of the design elements, stones or even equipment (pump, filter, thermometer).
In terms of their consistency, the eggs are so hard that even aggressor fish cannot bite through them. This nature protected the offspring of snails from predators.
Care for caviar is not needed. After 2-3 weeks from the moment of caviar deposition, small coils appear and begin to be absorbed.
The speed of this process depends on the quality of water and its temperature.
