The content and breeding in the aquarium predatory snail Helena

Helena snail is a predatory freshwater creature. Her homeland is Southeast Asia. Exotic lovers grow such snails in aquariums.

The peculiarity of this mollusk is that it eats other snails, smaller in size. This fact must be taken into account before purchasing them for home maintenance and placing them in one aquarium.

Helena snail refers to predatory creatures

Helena mollusc is distinguished by a yellow-striped color. In the wild, they are able to live from 1 to 2 years. Most often live in flowing water, preferring sandy or loamy substrates.

If in the aquarium such a mollusc eats small slugs, then in its natural environment large worms enter its diet.

The size of the predator varies from 0.5 to 1 cm. Characteristic features of this species are as follows:

  • elongated legs and breathing tube;
  • oral opening in the form of a proboscis, with which the mollusk opens other shells;
  • a number of small teeth are present on the oral proboscis.

Helens are not only decorative molluscs. They help clean the aquarium from small snails – coils, acroluxes and melanias, due to which the population of small mollusks will be controlled naturally.

However, it should be understood that Helena can completely clean the container from such slugs.

Of course, you can use different chemicals for this purpose, but they will not be as effective as this predator. Most of the slug products contain copper in their composition, and it is dangerous for fish, as it causes an imbalance in the biological environment of the aquarium.

It is impossible to distinguish the female Helena from the male on its own. To obtain offspring, it is recommended to start a fairly large number of such mollusks.

In order for the Helena snails to feel good in the aquarium and produce offspring, it is necessary to provide them with all the conditions. Particular attention should be paid to the size of the aquarium, water and additional food.

When choosing a tank, it should be borne in mind that for the normal existence of one individual it will be enough from 3 to 5 liters of water, but the more, the better. Immediately after the purchase is not recommended to put the snails in the general aquarium.

The first few weeks they must be kept in a separate container. You can “substitute” them to other inhabitants only when they grow up to 1 cm.

The main requirements for keeping snails in an aquarium are as follows:

  • water temperature – from 23 to 27 ° C;
  • acidity should be 7.2-8 pH;
  • water hardness – 8−15;
  • soil – gravel or sand.

If the water temperature drops to 20 ° C, then the helens will stop multiplying. At temperatures below 19 ° C, the clam stops eating.

Despite the fact that the predator snail eats smaller mollusks, it needs to be fed with additional food. The main diet consists of coils, fizy and melania.

Helena literally sucks the contents of the shell with her proboscis, but it is indifferent to large and very small mollusks, since it simply cannot eat them.

Frozen shrimp, bloodworm or ordinary fish food are suitable as additional feed. If there are small sick or dead fish in the aquarium, the predatory mollusk will gladly eat them too.

Reproduction of snails helen in an aquarium can take place only in the presence of heterosexual individuals. This means the more mollusks there are, the higher the chances of getting offspring.

The mating process itself is quite lengthy. It can last for hours.

Sometimes it happens that mollusks can stick together not in pairs, but in whole groups.

Reproduction of Helen snails in an aquarium can take place only in the presence of heterosexual individuals.

Eggs are laid on a hard surface. It may be a stone or a snag.

Masonry develops very slowly: After falling into the sand, eggs can lie there for several months. Grown up young individuals can only be seen six months after laying eggs. Open they begin to appear only when they reach about 7−8 mm.

Survival rate is rather low. The main reasons are cannibalism and competition for food in the period of their active growth.

Some aquarists specifically grow small snails in cans to feed them Helen.
