Snail care guide
Introduction
Keeping snails as pets is a rewarding and fascinating hobby, but their care requirements differ significantly from traditional pets. Snails thrive in a controlled environment that mimics their natural habitat, with proper humidity, temperature, and diet. Whether you’re new to snail keeping or looking to refine your setup, this guide covers everything you need to know about housing, feeding, and general care for a happy and healthy snail.
Unlike mammals or reptiles, snails require minimal daily maintenance but careful attention to their environment. With the right setup, they can live for many years, generally anywhere from 1-10 years for Cepaea species and provide endless enjoyment as low-maintenance yet intriguing pets. Let’s dive into the essentials of snail care.
Diet and Nutrition
Feeding your pet snails a varied and balanced diet is essential for their health and longevity. Cepaea nemoralis and Cepaea hortensis, like most land snails, thrive on a mix of fresh vegetables, fruits, and calcium sources to support their shell growth and overall well-being.
Staple Foods
Snails have a few favourite foods, with carrot and sweet potato being among the most popular. These provide essential nutrients, but it’s important not to rely on them exclusively. Snails can develop preferences and refuse other foods, so rotating their diet ensures they receive a broad range of nutrients and prevents over-reliance on specific items.
When eating a favourite food, Cepaea snails often point their eyes downwards, a behaviour that may indicate focused feeding or enhanced sensory engagement with the food.
Most fruits, vegetables, and salad leaves are suitable, but they should always be thoroughly washed to remove any traces of pesticides, which can be harmful to snails. Foods high in sugar, such as soft fruits, should be offered only occasionally as treats.
Vitamin D and Protein
Snails require vitamin D for proper shell development. A good source of both protein and vitamin D can be found in many commonly available fish flake products. Many snails enjoy fish flakes as part of their diet, and they provide an easy way to supplement essential nutrients.
Calcium Sources
Calcium is vital for maintaining a strong and healthy shell. Here are several excellent sources of calcium that you can provide:
Cuttlefish bone – A highly recommended option that is easy for snails to rasp and also contains magnesium.
Eggshells – A natural and inexpensive calcium source, but they should be thoroughly cleaned and crushed before offering.
Calcium carbonate powder – Can be sprinkled over food for an extra boost when necessary.
Calcium carbonate blocks – These calcium blocks provide a great source of pure calcium in the enclosure.
Extra Nutrition for Recovery
After laying eggs or emerging from hibernation, snails may need additional nutrition to regain their strength. Spirulina is an excellent supplement, providing a rich source of protein and essential nutrients. Premade health booster mixes are another great option, offering a blend of vitamins and minerals designed to support recovery and overall well-being.
Commercial Snail Mixes
A great way to ensure a balanced diet is by offering snail-specific food mixes. These often contain a blend of essential nutrients, including calcium and protein, making them a convenient supplement to fresh foods.
By providing a diverse diet and ensuring access to essential nutrients, you can keep your snails healthy, active, and thriving.
Habitat and Enclosure Setup
Providing the right habitat for your snails is key to keeping them healthy and comfortable. While there are many suitable enclosures, they must meet certain requirements to ensure proper humidity, hiding spots, and a stable environment.
Humidity and Ventilation
Snails thrive in a humid environment, but how this is maintained depends on the type of enclosure:
Well-ventilated enclosures require daily misting and a small water bowl to maintain adequate moisture levels.
Less ventilated enclosures naturally retain more humidity and require less frequent misting.
Finding the right balance is important—too much humidity can encourage mould growth, while too little can lead to dehydration or prolonged aestivation (a form of dormancy in response to dry conditions).
Hiding Spots and Stability
Snails establish a home range within their enclosure, meaning they develop favourite locations for resting and hiding. Providing hides is essential for reducing stress. Some good options include:
Half a coconut shell to create a cave.
Pieces of cork bark to provide shelter.
Although snails may be less visible when given hiding spots, they will be more relaxed and active when they do emerge. To avoid unnecessary stress, it’s best not to rearrange or disturb their environment too often.
Aestivation and Hibernation
Snails can survive a wide range of conditions, but extreme temperatures or dry conditions can trigger a state of dormancy:
Aestivation occurs in response to heat or dryness. While some snails naturally aestivate for weeks at a time, prolonged aestivation may indicate that conditions are too dry or too warm.
Hibernation is less common for pet snails, as indoor temperatures are usually stable, but it can occur if temperatures drop significantly.
Keeping a consistent, suitable climate in the enclosure will help prevent unnecessary dormancy.
Substrate and Microbial Balance
The right substrate supports natural behaviours like burrowing, hiding, and egg-laying. Choosing a suitable substrate is crucial for maintaining a healthy and stable environment for your snails.
Best Substrate Options
Coco coir – Retains moisture well and allows for burrowing.
Moss – Helps maintain humidity and provides a soft surface for snails.
These materials help create a naturalistic habitat, mimicking the leaf litter and soft soil found in the wild. The substrate should always be kept moist but not waterlogged, as excessive moisture can lead to mould growth and fungal issues.
Maintaining Microbial Balance
While enclosures should be cleaned periodically—especially the glass or plastic walls to maintain visibility—it’s important not to make the habitat too sterile. A microbe-rich environment helps prevent bad odours and supports the snails’ health.
Completely replacing the substrate too frequently can disrupt beneficial microbes and create more maintenance rather than reducing it. To maintain a balanced ecosystem, consider adding:
Biochar – Helps control odours and supports microbial health.
Springtails – Tiny beneficial insects that help break down and recycle waste.
Live plants – Provide a natural aesthetic, help maintain humidity, and assist in recycling waste in the soil.
By creating a stable, naturalistic habitat, you can ensure your snails feel secure, stay active, and remain in good health.
Handling and Safety
Handling your snails correctly is important to ensure both their safety and yours. While pet snails are unlikely to carry diseases like some wild snails might, proper handling techniques help prevent harm to the snails and maintain good hygiene.
Washing Hands Before and After Handling
Always wash your hands before and after handling your snails. Snails have delicate skin that can easily absorb substances from human hands, including:
Natural oils
Lotions
Perfumes and aftershave
Other chemicals or residues
Even small traces of these substances can be harmful to snails. Similarly, after handling, washing your hands ensures that any bacteria or snail mucus is removed. While pet snails are generally clean, good hygiene is always recommended.
Avoiding Harmful Substances
Snails are highly sensitive to chemicals in their environment. Avoid using aerosol sprays, perfumes, or cleaning products near their enclosure. Even airborne particles can be absorbed through their skin, potentially leading to health issues.
Safe Ways to Pick Up a Snail
Snails should never be picked up by their shell when they are actively moving, as their foot can grip onto surfaces tightly. Attempting to lift them by the shell while they are attached to a surface can cause serious injury, potentially tearing their body or damaging internal organs.
Instead, follow these safe handling methods:
If the snail is on a smooth surface, gently slide it forward or backward to loosen its grip before lifting.
If the snail is on a rough or textured surface, avoid trying to remove it, as its grip will be stronger, increasing the risk of injury.
The safest time to pick up a snail is when it is fully inside its shell, as it is not actively gripping anything.
By handling your snails gently and carefully, you can avoid unnecessary stress or injury, ensuring a safe and comfortable experience for both you and your snails.
Health and Common Issues
Keeping an eye on your snails’ health is crucial to ensuring they remain happy and active. While snails are generally low-maintenance, there are a few common health and habitat issues that can arise. Regular observation and prompt action can help keep your snails in top condition.
Shell Health and Growth
The shell is a great indicator of a snail’s overall health. Actively growing snails will show visible growth lines, which are natural markers of periods of stress or strong growth.
When conditions are ideal, snails experience consistent growth, and their shells appear smooth and uniform.
When snails grow in inconsistent or stressful conditions, their shells may develop deformities or irregular growth lines.
Adult snails stop growing once they reach maturity, but their shells can still show signs of aging. The periostracum, the thin outermost layer of the shell, may begin to fade or flake off, giving the shell a white or worn appearance.
For younger adult snails, if the periostracum fades or peels excessively, it usually indicates that humidity levels are too high and adjustments should be made to the enclosure.
Deep Retraction Syndrome
Some snails, especially older or weaker individuals, may show signs of deep retraction syndrome. In this condition, the snail withdraws deeply into its shell and becomes immobile for extended periods.
This is typically a sign of aging or weakness, but it can also be caused by:
Poor diet or lack of calcium
Incorrect humidity levels
Temperature fluctuations
Stress from handling or environmental changes
If a snail exhibits deep retraction, check their environment and ensure optimal conditions to support their recovery.
Mantle Collapse
Mantle collapse is a serious condition that occurs when the snail’s mantle (the soft body tissue inside the shell) becomes damaged or detached. This is often due to improper handling, such as:
Lifting the snail too forcefully from a surface.
Dropping or shaking the snail.
If a snail experiences mantle collapse, it may struggle to retract properly into its shell, and in severe cases, the shell may detach from the body. Unfortunately, this condition is often fatal, so careful handling is essential to prevent injury.
Snail Mites
Mites are a common issue for wild snails but are unlikely to affect pet snails. These tiny parasites can irritate snails by feeding on their body fluids. If mites are observed:
Introducing hypoaspis miles (a type of predatory mite) can help eliminate them naturally.
Keeping the enclosure clean and free of wild soil reduces the risk of mite infestations.
Fungus Gnats
Fungus gnats are a common pest in terrariums, thriving in moist soil. While they don’t harm snails directly, they can become a nuisance.
To prevent infestations:
Remove uneaten food to prevent attracting gnats.
Use yellow sticky traps to capture adults.
Add a top layer of dry sand or fine gravel to the substrate to prevent larvae from thriving.
Introduce predatory nematodes, which naturally eliminate gnat larvae without harming snails.
Dehydration and Over-Hydration
Snails require moisture to thrive, but too much or too little can lead to health issues.
Dehydration occurs when humidity is too low, causing snails to retract into their shells and remain inactive.
Over-hydration happens when the enclosure is too damp, which can encourage mould growth and fungal infections.
To prevent hydration issues:
Mist the enclosure regularly to maintain the correct humidity.
Ensure proper ventilation to prevent excessive moisture buildup.
Provide a small water dish, but ensure it is shallow to avoid drowning risks.
By maintaining optimal conditions and monitoring snail behaviour, you can help prevent these common health issues and ensure your snails live long, healthy lives.
Breeding and Reproduction
Snails are hermaphroditic, meaning each individual possesses both male and female reproductive organs. This allows them to mate with any other snail of the same species. After mating, both snails will lay eggs, which will hatch into baby snails.
Breeding Setup
To encourage breeding, snails need a stable environment with the following conditions:
Adequate space – Snails prefer a spacious enclosure, which helps reduce stress.
Calcium availability – Ample calcium is vital for egg development. Provide cuttlefish bones, crushed eggshells, or other calcium-rich foods.
Moisture levels – Humidity should be around 70-90%, as this is ideal for egg-laying. Extreme dryness or excessive moisture can affect the fertilisation process and egg incubation.
Egg Laying and Incubation
After mating, snails will typically burrow and lay their eggs in the substrate. The number of eggs laid varies by species, but Cepaea snails can produce anywhere from 20 to 100 eggs per clutch.
Eggs are usually deposited in small holes dug in the soil or substrate.
They take around 2 to 4 weeks to hatch, depending on temperature and humidity.
Higher temperatures within a stable range (22-25°C) generally speed up the hatching process.
Handling Snail Eggs
Once eggs are laid, you have two options depending on whether you wish to breed snails:
Hatching the Eggs
If you want the eggs to hatch, leave them in place or carefully transfer them to a separate breeding enclosure.
Use a soft, moist substrate, and keep humidity around 80%.
Ensure the enclosure has adequate ventilation to prevent mould.
Preventing Overpopulation
If you do not want to breed snails, the most humane method of disposal is freezing the eggs.
Collect the eggs and place them in a sealed container in the freezer for 24 hours before disposal.
This prevents hatching and is recommended for responsible population control.
Caring for Baby Snails
Once the eggs hatch, tiny juvenile snails emerge. These baby snails are fully formed but require gentle care to ensure survival.
Keep them separate from adult snails to prevent accidental injury.
Maintain a moist, stable environment with adequate food supply.
Provide a calcium-rich diet to support shell development.
Ensure food is finely chopped or soft to accommodate their small size.
With proper care, baby snails will grow steadily, eventually reaching maturity within a few months to a year, depending on species and environmental conditions.
Conclusion
Caring for pet snails is a fascinating and rewarding experience that requires attention to their diet, habitat, and overall health. By providing a suitable enclosure with proper humidity, a varied and nutritious diet, and a safe environment, you can ensure your snails thrive and live a long, healthy life.
Regular observation and gentle handling will help you understand their behaviours and detect any potential health issues early. Whether you’re keeping snails as a hobby or breeding them, maintaining a balanced and naturalistic environment will support their well-being and allow them to display their full range of natural behaviours.
By following the guidelines in this care guide, you’ll be well-equipped to create a comfortable and enriching home for your snails, ensuring they remain happy, healthy, and active for years to come.
