Among aquarists, the Helena snail is popular, which eats other snails. Area: reservoirs with running water, as well as lakes and ponds of Southeast Asia.
Body elongated, breathing tube present. Body color is gray-green. The size of the shell is 15–28 mm, diameter 7–13 mm.
Conical shell with frequent ribs, yellow with a spiral dark stripe. Freshwater snail lives 2–5 years.
Lifetime is reduced by high temperatures and inappropriate conditions.
Helena is fighting with small snails and other unwanted guests in the aquarium:
- pond cleaners;
Ulitkoed digs its proboscis into the body of other snails, leaving only a shell. Moves fast.
Helena is safe for fish, aquarium crabs, crayfish and shrimp. Large mollusks (ampoules) are not attacked.
Exceptions are young individuals. It can destroy the population of snails, so the number of predators should be minimal.
The predatory snail is unpretentious, survives at different parameters of water.
As with many snails, the maintenance of Helena does not require a large tank and careful maintenance of the aquarium.
Settle one individual in a 20–30 liter aquarium. For solitary confinement, an aquarium of 3-5 liters is suitable. For breeding need a capacity of 110 liters. Mandatory cover to avoid crawling out of the animal.
Do not let the water parameters change abruptly and do not populate the mollusks in soft water so that the shell does not collapse. Keep the water clean.
Aeration is not required.
In a Helen aquarium, fine soil with a diameter of 1–2 mm is preferred, in which the snail buries. Able to live in a tank with soil of medium size.
With greater desire eats prudovikov and coils, with the least – melania because of kinship with this species.

In addition to the small snails for feeding these carnivores are suitable:
- vegetable food with algae;
- beef heart and liver;
- sinking fish food;
Having settled with all the snails, Helena eats food leftovers for aquarium fish. If the diet of fish contains little protein, feed Helen snails.
Dissolve coils in a separate container or nat so that predators always have food. One medium-sized snail is enough for a couple of days.
Also suitable for feeding chicken eggs.
Helena is dangerous for gastropods of the same size. Sometimes attacked:
- sedentary fry;
- shrimp during molting;
- fish roe.
Do not place Helen in the spawning tank and “nursery” for the young. If you keep rare species of shrimp, it is better to be safe and not to keep them with killer snails.
The small size of the mollusks does not allow them to be kept with large cichlids, since the latter eat Helens. To the vegetation indifferent.
Predators breed on reaching 6 months, when they grow up to 1 cm. Unlike coils or melania, they breed slowly.

Helens are mollusks of opposite sexes, which means that it may not be enough to breed two individuals.
It is impossible to determine the sex before mating. During the breeding season, heterosexual heles form pairs and stick together.
Place 4–6 individuals in the aquarium. Maintain a temperature of 20 degrees, feed the producers of high-quality protein feed.
Pairing gastropods can last several hours. Females lay on one egg, placing the clutch on glass, decorations, pebbles and other solid objects.
The masonry is square with a brown dot in the center.
Incubation time 25-30 days. The hatched individual buries the soil and is shown on reaching 3-4 mm.
Not all offspring survive, although adults usually do not touch the young. At first the mollusks feed on the remains of fish food.
They begin to hunt, growing to 7–8 mm. During the growth of young stock, carefully monitor the purity and parameters of water.
Helena exercises natural control of the snail population in aquariums.
The aquarists’ descriptions are similar: many at first did not notice how Helena fights with mollusks, but in a couple of months the reduction in the number of gastropods was noticeable. It is recommended not to keep too much helen in order to maintain the balance of edible mollusks and predators.
On average, the price of 1-1.5 centimeters is 60-90 rubles.
- In order not to introduce undesirable mollusks and parasites, rinse and process newly acquired plants in a solution of 3% hydrogen peroxide (5 ml per 10 l of water) or light pink potassium permanganate solution. Exposure time from 30 min. A low whiteness solution is also suitable (25 ml per 1 l of water) with an immersion of 3–5 minutes. Remember that chlorine is not tolerated by all plants, for example, it is harmful for elodea.
- The complete extermination of snails-orderlies is as bad as an overgrown population. Gastropods are useful for removing green deposits from glass and loosening the soil, which saves it from oxygen-free zones. Keep track of the number of predators and “prey” or keep Helen with large snails such as ampulyaria.
- If phytophagous snails do not eat algae, temporarily stop their feeding.
- To prevent water from blooming, do not allow the sun to hit the walls of the aquarium.
Helena has two Latin names: Anentome helena and Clea helena. This is due to two genera of Asian and African descent.
