The cheap, low-effort starter mollusk that must never, ever be set free.
The Garden Snail (Cornu aspersum, formerly Helix aspersa) is a 1-1.5 inch land snail kept in simple vented tubs, living 2-5 years with good moisture and calcium. It is one of the cheapest, easiest invert pets and is popular with children.
The serious red line is biosecurity: it is a major agricultural pest in many regions, so it must never be released outdoors and some areas restrict keeping or importing it. Always wash hands after handling and keep a tight lid, as snails climb glass.
In a damp, cool setup with calcium they live about 2-5 years, and can hibernate in a sealed shell during dry or cold spells, which is normal.
What do Garden Snails eat?
Feed leafy greens, cucumber, carrot, and a cuttlebone or crushed eggshell for calcium daily, with a shallow water dish or daily misting. Avoid salty or processed food, which harms them.
Enclosure setup
Use a 5-10 gallon vented tub with 2-3 inches of coco fiber or soil, 65-75°F, and 70-80% humidity via daily misting. Add a cuttlebone and a secure, escape-proof lid.
Common mistakes with Garden Snails
Usual errors are letting the tub dry out, no calcium so the shell deforms, feeding salted food, and releasing them outside, where they are invasive agricultural pests.
Beginner mistakes to avoid
Letting the enclosure dry out, which kills the snail.
No calcium source, so the shell grows thin and cracks.
Feeding salty or seasoned food that poisons them.
Releasing them outdoors - they are invasive pests in many places.
