The snails can survive in soft and hard water without any problems. However, more lime is always better in order to form a more robust shell. Accordingly, special snail food or a total water hardness of 10 is recommended for long life.

The shell is also very sensitive to an acidic environment. This attacks the housing and causes smaller holes. Apart from that, little can harm the animals. Many breeders and keepers like to let their darlings overwinter in the garden pond. This should then be at least 80 centimeters deep and be able to hold at least 200 liters of water.

The snail itself is usually the greatest danger to health. Overpopulation can upset the balance in the pond or Aquarium. This can also lead to problems for other inhabitants of the biotope, especially for the often socialized shrimp.
