It is the ideal snail species for beginners, as it is relatively undemanding and easy to care for. It is fitting that she feels as comfortable in a cold-water aquarium as she does outside in the garden pond. And the multiplication is almost a breeze.

The Spitzschlammschnecke is characterized mainly by its housing. It is relatively thin and tower-shaped and rechtsgewunden. The housing of a full-grown animal always has 7.5 turns, which increase evenly in the lower part, but very quickly upwards. Characteristic is a very long tip that gives the slug its colloquial name. The soft body inside the case has a gray to brownish color. The feelers, in turn, are relatively large and triangular. The eyes are at the base of the antennae. Depending on the habitat, Spitzschlammschnecken can look different, as they have adapted over time to the specific living conditions.


Spitzschlammschnecke - Spitzhornschnecke - Lymnaea stagnalis

The Spitzschlammschnecke is a water snail, but can not live permanently under water. From time to time she has to show up to take a breath. She has a so-called lung cavity, which she fills with air at the water surface. The species belongs thus to the subordination of the water snails. As such, it is the largest water lung snail in Central Europe. Lymnaea stagnalis is a hybrid. For fertilization, however, it absolutely needs at least one other animal of its kind. However, fertilization does not take place as in many other types of snail mutually, but always only one-sidedly.


The attitude of Spitzschlamschnecken requires very little effort. It can take place both in an aquarium and in the garden pond. In the pond, the animals are outstanding remanufacturers, who mainly kill dead parts of plants. However, you will hardly be able to watch them there. Who wants to deal with these stately snails closer, therefore, does not pass the aquarium attitude. However, one should be aware that in all likelihood they will eat all the plants in the aquarium. Therefore, they are hardly suitable for a classic show aquarium. Of course, they can easily handle fish and other aquatic animals. It is important that they are only socialized with fish, which are rather calm and, above all, peace-loving. Otherwise it is important to note the following when keeping slippery snails in the aquarium:
  • Attitude only possible in the cold water aquarium
  • Tank size: at least twelve liters, better more
  • Water temperature: ideal is room temperature up to a maximum of 25 degrees Celsius
  • Water hardness: can be tolerated pH values ​​from 6.5 to 9
  • Soil is not essential, but should not be made of sand, as the snail can not move on it
Tip: Those who hold Spitzschlammschnecken in an aquarium and do not want to do without a substrate, should resort to stones, coarse gravel and possibly fallen leaves.


Spitzschlammschnecken are in principle omnivores, which taste vegetable food as well as animal. In the wild, they feed mainly on algae and dead plant parts. A feeding in the pond is therefore usually not required. In the attitude in the aquarium you can not ignore it. Recommended here is the feeding with fish dry food, lettuce leaves and other green fodder. Food leftovers should be removed from the water regularly to prevent decay processes.
Note: Spitzschlamschnecken eat in the aquarium also coverings with green Hydra and thus reduce in a very natural way the infestation by this freshwater polyps.


Spitzschlammschnecken can be reproduced almost easily in the aquarium. It only needs at least two animals. After fertilization, up to 300 eggs per animal are placed in gelatinous, up to four centimeters long strings under water.The animals prefer to attach these cords to the leaves of aquatic plants, to flat stones or even to the glass panes of the aquarium. Finally, the young snails develop from the spawn. Depending on the water temperature, it takes about two weeks to hatch. In case of a possible overpopulation, the adult snails will eat the spawn first. Incidentally, the animals multiply year round, not to say constantly. Young animals are already mature after about ten weeks and start to multiply.
Note: Spitzschlammschnecken become less old when keeping in the aquarium than in the wild. The life expectancy here is about two years.

Spitzschlammschnecke - Spitzhornschnecke - Lymnaea stagnalis

Anyone who wants to keep slime slugs in a garden pond, usually does that to reliably rid the body of dead plant remains. You hardly get to see the animals. At most, one can catch a few glances when they come to the water surface to fill up with air. As they are water snails, they will not leave the pond either. So you do not have to worry about the salad in the bed. However, if the pond is planted, there is a risk that the animals hack over these plants. Frequently the spawning of the Spitzschlammschnecke is introduced by birds into the pond.

Diseases and pests

Spitzschlammschnecken are extremely robust and resistant animals. In the aquarium they are practically unaffected by diseases. As a rule, they can only become animals that eat snails. This may be the case with certain fish or cancers. The attitude in combination with shrimp, however, is not a problem. It should always be kept in mind that Spitzschlammschnecken can not retreat so far into their housing as other types of snails. It therefore only provides them with conditional protection. The so-called foot will always be reachable for any predators. Injuries to the foot can possibly lead to the death of the snail.
