Snail Housing Requirements
Proper housing is essential for your snail's health and longevity. Requirements vary by species.
Enclosure Setup
- Terrarium size: Minimum 5 gallons for small species, 10+ gallons for giants
- Substrate: 2-4 inches of coconut fiber or pesticide-free soil (for burrowing species)
- Humidity: 70-90% for tropical species, mist daily (use hygrometer to monitor)
- Ventilation: Screen top to allow air exchange while maintaining humidity
- Hides: Cork bark, clay pots, or half-buried containers provide security
- Plants: Live plants like pothos or sphagnum moss help maintain humidity
Temperature & Lighting
- Temperature: 70-78°F for most species (use under-tank heater if needed)
- Lighting: Indirect natural light or low-wattage bulb (no UVB required)
- Day/night cycle: 12 hours light/12 hours dark mimics natural rhythm
- Heating: Use thermostat-controlled heat mat if room is cold
Pro Tip: Creating Microclimates
Create humidity gradients by having deeper substrate on one side of the enclosure and misting that area more heavily. This allows snails to choose their preferred moisture level. Use sphagnum moss in humid areas to help retain moisture.
Snail Nutrition Guide
A proper diet is crucial for healthy shell growth and overall snail health.
Diet Components
- Vegetables: Leafy greens (kale, romaine, spinach), zucchini, cucumber, sweet potato, carrots
- Calcium sources: Cuttlebone, eggshells, oyster grit, calcium powder (essential for shell growth)
- Protein: Fish flakes, boiled egg, bloodworms (once weekly for most species)
- Fruits: Occasional treats (apple, banana, melon) - high sugar content
- Avoid: Salty, processed, or acidic foods (citrus, onions, garlic)
Feeding Schedule
- Frequency: Offer fresh food daily, remove uneaten food after 24 hours
- Quantity: About as much as the snail can eat overnight
- Preparation: Wash thoroughly, cut into snail-sized pieces
- Variety: Rotate different vegetables to ensure balanced nutrition
- Calcium: Always available - place cuttlebone in enclosure
Foods to Avoid
- Toxic plants: Ivy, oleander, buttercups
- Processed foods: Bread, pasta, salty snacks
- Acidic foods: Citrus, tomatoes, vinegar
- Pesticides: Always use organic produce or wash thoroughly
- Dairy: Snails cannot digest lactose
Calcium Requirements
Snails need constant access to calcium for shell growth and repair. Provide multiple calcium sources: crushed eggshells mixed into substrate, whole cuttlebone, and calcium-rich vegetables like kale. Signs of calcium deficiency include thin, cracked, or peeling shells.

Snail Breeding Guide
Understanding snail reproduction is important whether you plan to breed or prevent unwanted eggs.
Egg Laying
- Most land snails bury eggs in substrate
- Clutch size varies by species (30-400 eggs)
- Incubation period: 2-4 weeks depending on temperature
- Eggs are small, round, and pearly white
Hatching
- Babies emerge with soft, transparent shells
- First meal is often their own eggshell (calcium source)
- Extremely vulnerable to drying out
- Require same diet as adults, just smaller portions
Juvenile Stage
- Rapid growth with proper nutrition
- Shell becomes more opaque and colored
- Sexual maturity reached in 6-24 months
- Mortality highest in first few months
Adult Stage
- Full size reached in 1-3 years
- Reproductive prime varies by species
- Can produce multiple clutches per year
- Lifespan ranges from 2-15 years depending on species
Breeding Basics
- Hermaphrodites: Most land snails have both male and female organs
- Courtship: Can last several hours with elaborate rituals
- Egg care: Generally no parental care after laying
- Temperature: Warmer temps usually increase breeding activity
- Population control: Freeze unwanted eggs before disposing
Responsible Breeding
Only breed snails if you have homes lined up for all offspring. Many snail species are prolific breeders and can quickly overwhelm your capacity. Consider that some species like Giant African Land Snails are illegal to keep in some countries due to their invasive potential.
Handling & Interaction
Proper handling techniques ensure your snail's safety and reduce stress.
Safe Handling Techniques
- Wash hands thoroughly before and after (no lotions or soap residue)
- Handle over soft surface in case of falls
- Let snail crawl onto your hand rather than pulling it
- Support the shell fully - never hold by the shell opening
- Limit handling to 10-15 minutes to prevent drying out
- Keep away from face (some species may carry parasites)
Handling Precautions
- Avoid handling when snail is sealed in shell (indicates stress)
- Never force snail out of its shell
- Don't handle snails during extreme temperatures
- Supervise children closely during handling
- Wash produce thoroughly to remove pesticide residue
Bonding With Your Snail
While snails don't bond like mammals, they can learn to recognize safe environments. Regular, gentle handling at the same time each day can help your snail become more comfortable with interaction. Observe your snail's behavior - if it consistently retreats when handled, reduce handling frequency.
