Dear colleagues! Today I would like to talk about a small aquarium dweller protected by armor.
Today it will be a snail coil. In nature, it is found in freshwater bodies of Russia and Ukraine and other countries.
You can easily find them in standing not deep water bodies and shallow creeks overgrown with vegetation. In such bodies of water a huge amount of decaying vegetation, in which the snail hides and feeds simultaneously.
In aquariums, however, we live mostly in clams from tropical regions of our planet.
Externally, the clam shell resembles a flat, tightly twisted spiral in which an elongated conical body hides. The color of the shell is no different from the color of the body.
The diameter of the shell in an adult mollusk can reach 1 centimeter. A snail moves in a pond with a flat foot, which is perfectly visible when moving.
On the head there are several thin tentacles, at the end of which there are light-sensitive cells that serve as clam eyes. In amateur aquariums, there are mainly three types of coils:
It lives in stagnant waters of Siberia, the Caucasus, Europe and Asia. Since the snail likes to hide from the eyes of an aquarist, the best shelter for her are overgrown plants.
The shell is quite durable and it is painted brown. The shell of adult individuals has up to 5 turns, which will increase in size to the outer diameter.
If you look closely, then between the turns you can see the seam. The shell diameter of the horn coil can reach 3.5 centimeters with a width of 1 centimeter. The body of the coil is red-gray in color.
The mollusk feeds mainly on bottom sediments.
In nature, this mollusk is found in swamps, lakes and rivers of the Eastern part of Asia. This type of coil is quite unpretentious aquarium inhabitant, which adapts to almost any conditions. On the reddish-brown shell there are oblique lines.
The greatest number of turns of the shell, which met – is 6 pieces. The diameter of the shell in an adult mollusk is 1 centimeter with a width of 3.5 millimeters.
Snails eat almost all types of aquarium plants.
This mollusk has more modest dimensions in contrast to the ordinary horn coil (no more than 2 centimeters). In addition, the color of their shell is purple-red, which looks good against the background of overgrown aquarium plants.
This type of coil is considered an excellent orderly aquarium. If mollusk food is abundant, then it is not aquarium plants.
But an aquarist must constantly regulate their numbers, as these snails are famous for their fertility.
As I already mentioned above, the coils perfectly survive in various aquarium conditions and they easily endure rather wide temperature ranges. But it is best to keep them together with tropical fish. Additionally, there is no need to feed the pets, as they constantly eat up the remnants of not eaten food, green fouling on the glasses and plants, as well as rotten leaves of the plants.
Also, these mollusks can pick up on the surface of the remaining underfed fish feed and bacterial film on the surface of the water. Often you can see a cluster of small snails on a rotted leaf of the plant. Immediately I would like to note that mollusks do not eat healthy aquarium plants.
If the population is growing steadily and the aquarist does not regulate it, then the cochlea greatly shrink in size.
I would also like to note the amazing feature of the coil to float on the surface of the water while its sink remains upside down. To move like this, the snail has to run air into the sink. A support for the movement of the cochlea is either the surface tension of the water or the bacterial film.
If you decide to touch her during such a march, he will immediately release the air from the sink and dive to the bottom with a stone. This is a kind of conditioned reflex to a predator. It was noted that the coils survive quite well in poor waters for oxygen.
This is achieved by assimilation of atmospheric air due to the special pulmonary cavity.
The coil is a hermaphrodite that can self-fertilize and further multiply. Therefore, if you want to get a population of these snails, then you will only need to have only a couple of individuals. The laying of the calf snail attaches to the inside of the leaf of the aquarium plant.
In general, the population of snails in aquariums is regulated without the intervention of an aquarist, as aquarium fish happily eat young snails. But if the fish are full, then they will not touch small mollusks. If you notice a rapid increase in the population of snails, then this suggests that you are overfeeding your fish.
Therefore, you only need to cut the rations of fish and pens to get snails from the banks.
There are cases when aquarists purposefully breed snails, because they go to feed some pets or fish (batyami). In this case, it is not necessary to fill up the soil in the aquarium, as this will complicate the process of cleaning the aquarium. Place in the jar several species of floating plants (naiad, pistia, riccia, javanese moss).
If they could not be found, put on Vallisneria, Canadian Elodea, or rogolistnik. You can feed the snails with dry food for fish and scalded cabbage, lettuce and spinach leaves.
