In some cases, the number of “population” of the aquarium is reduced in a natural biological way. An example of an event is an operation called “Helena Snail”. In the course of it, one biological species of snails destroys others, small, weak.
Action benefits. The observation process is fascinating.
Most importantly, the action helps to regulate the number of breeding living creatures (snails coils).
Aquarium life is characterized by independent regulation. Predatory snail Helena leads an unusual lifestyle.
The peculiarity of food: relatives, smaller in size. Helena is a native of Southeast Asia. In nature inhabits lakes, ponds.
Prefer running water stagnant turbid mixture.
Native home – sandy, silty substrates. Adult snail loves to dig in the ground, wait out the daytime.
Parental instinct implements a similar tactic: kids, ripening, are in a buried state.
Aquarium life began recently, a decade ago. Helena managed to gain popularity.
The ability for 2-3 months is safe for fish to clean the aquarium from the breeding coils – a valuable individual feature.

Appearance predator attractive. The shell size does not exceed 20 mm, the coloring is regarded as a bright, screaming yellow range of alternating dark brown, amber stripes running in a spiral. Often the pattern is decorated with black dots, giving the appearance of attractiveness.
An interesting appearance is complemented by a cone-shaped shell.
The body of the snail itself is gray-green, similar to the appearance of classical species, is invisible in the photo and video.
The difference between snails is the ability to move quickly. It is necessary to catch up the victim, hunting, you can not keep up in the thickets of vegetation, overcome obstacles caused by design elements.
The life of a home aquarium has developed a number of habits in Helena:
- soft water is not desirable (harms shell strength);
- loves fresh water, is able to adapt to the conditions with the addition of salt;
- the soil prefers soft, flowing (fine gravel, sand), with a consistency close to the native element. It does not complicate the hobby – inside is the untimely pastime;
- stagnant water – a pledge uncomfortable stay for Helena. It is better to observe the regime of change, to monitor the purity.
Keeping snail helena is easy. Living conditions are similar to the most elementary, living neighbors – of little interest.
A comfortable stay is ensured by the amount of water volume of 3-5 liters for one individual. The principle “more is better” is directly confirmed.
Optimal couple settled in a 20-liter aquarium.
Life expectancy ranges from one to three years, depending on the conditions created.
The optimum water temperature is 21-23 ° C, but fluctuations of 2-3 ° C are easily tolerated. Lowering the temperature of the water below 18 ° C, provokes Helena to refuse to eat.
Living in natural conditions, Helena picks up “snail carrion”, eats it, due to this there is. Can eat fish if they are dead and unable to move.
From the moment of graying in the aquarium, live snails (fizy, melania, coils, ampulyaria) were in her diet. Having a special device (a tube at the end with an oral opening), Helena directs it into the shell of a living snail and sucks out all its internal contents, leaving behind it a pacifier – a shell, which eventually becomes lifeless gray.
Helena does not hunt large snails, but the red-brown “trifle” can be eaten by it almost completely cleaned.
If there is no “live feed” in the aquarium, you can feed the predatory Helen with any feed used for fish, including live, vegetable, dry and frozen. For shrimp, you can not be afraid – as food they are not suitable for carnivorous Helens.
It is worth considering in advance what Helen’s “children” will eat if they are purchased at an early age and run into a common aquarium. They will not be able to find their own food and will die before reaching an adult state.
Therefore, in the aquarium there is a rule: snails Helena should grow to the size of mature individuals in a separate aquarium, in the presence of a special feed. In this case, suitable bloodworm, chopped frozen shrimp, food for catfish.
Adapting to the aquarium life, Helena can successfully multiply. To do this, they must reach the age of six months.
Unlike snails of coils, helens are not hermaphroditic, division by gender is present. Looking closely, there are noticeable external differences between female and male individuals.
Reproduction of the snail helena occurs by mating. It is slow, often proceeds with the participation of not only a certain pair of “parents”, but a whole group of snails sticking together.
Even the stage of preparation for reproduction is interesting. A pair of “parents” who choose each other begin to closely contact. They spend their days, practically leaning against each other, taking turns climbing each other on their backs, as if they were riding.
It is better to deposit such a couple in another aquarium in order to ensure their peace at the time of caviar deposition.
As fertilization occurs, the female lays a single egg, which she tries to place on a stone, a snag, or simply a hard surface. Given that one egg is produced at a time, and even that is not a guarantee of its final development, helen reproduction is a long-term question.
The egg is a small square vial, inside it is a yellow egg. Maturation requires a period of at least 2-4 weeks.
Preferring such aquarium inhabitants and being interested in breeding them, aquarists always buy the Helen company and expect offspring from them.
When the egg goes into the stage of maturation, a young snail hops out of it, which immediately digs into the ground. Being there for several months, it further stretches the process of obtaining snail offspring.
When the size of the snail child reaches 5-8 mm, it comes to the bottom surface and begins an independent life.
The content of Helen is intended to determine in advance their possible neighborhood. Compatibility with fish, even very small ones, is not dangerous to anyone.
If a scene catches the eye when a snail eats a fish, then, most likely, it has already died or is seriously ill. Live mobile fish, like shrimp, Helena does not catch up, and will not try.
She will find something to eat elsewhere.
She can eat fish and shrimp caviar if she finds and can reach it. Fish fry, moving quickly and hiding from danger, are also of no interest.
An objective assessment of the degree of benefit or harm from its content is possible with careful observation of the number of individuals inhabiting the aquarium and the quality of their life.
When organizing the proper care of a water house inhabited by snails, aquarists often wonder: Will they damage the plants, bite young shoots or strong formed leaves?
Such questions arise for a reason. Many species of snails are capable of replacing it with plant food when there is a shortage of animal food. They gnaw (if you can call it a soft chewing apparatus of their mouth) available branches.
More often it happens with outdated, rotting leaves. For this reason, disputes among aquarists do not fade: are snails harmful to the plant world?
With regard to Helen, there is an unequivocal opinion: they are not interested in vegetation. Replace it with animal feed, they will not.
This explains the possibility of regulating the number of snails in a natural way: if there is a lot of food for them, they multiply intensively and quickly increase their numbers. If the feed is not enough, they stop laying eggs and reproducing their own kind.
