Mystery Snail Care 101: The Ultimate Guide to Keeping Your Pet Happy and Healthy

If you’re looking for a unique and low-maintenance addition to your aquarium, a Mystery Snail might be just what you need. These peaceful creatures are easy to care for and can add a pop of color to your tank. However, before you bring one home, there are a few things you need to know to ensure that your snail stays happy and healthy.

Mystery Snail prefers pH levels between 7.0-8.0 and a temperature range of 68-82°F. They are herbivores and need a varied diet of algae wafers, vegetables, and occasional meaty foods. They are also effective scavengers and help keep the tank clean. Regular water changes and tank maintenance are important for their health. They also require calcium supplements to maintain shell health.

First and foremost, you need to make sure that your tank is suitable for a Mystery Snail. These snails require a minimum tank size of 5 gallons and prefer a pH level between 7.0 and 8.0.

They also need a source of calcium, such as a cuttlebone or crushed coral, to help maintain their shells.

Additionally, Mystery Snails are not compatible with all fish, so it’s important to do your research before introducing them to your aquarium.

When it comes to feeding your Mystery Snail, they are not picky eaters. They will happily munch on algae, fish food, and even vegetables like zucchini or cucumber.

However, it’s important to avoid overfeeding as this can lead to water quality issues. With a little bit of research and some basic care, your Mystery Snail can thrive in your aquarium for years to come.

Mystery Snails

Species Summary

If you’re considering adding a Mystery Snail to your aquarium, it’s important to know some basic information about them.

Here’s a quick summary of what you need to know:


Mystery Snails are native to South America, specifically Brazil, Bolivia, and Peru. They can be found in rivers, ponds, and other bodies of freshwater.


Mystery Snails can live for up to three years in captivity if they are provided with proper care and a healthy environment.


Mystery Snails have a unique appearance that sets them apart from other snail species.

They have a round, spiral-shaped shell that can come in a variety of colors, including black, gold, and blue. Their bodies are typically a light gray or beige color, and they have two sensory tentacles on their heads.


Mystery Snails can grow up to two inches in diameter when fully mature.

Growth rate

Mystery Snails grow at a moderate rate, and their growth can be influenced by factors such as water quality, temperature, and diet.

Behavior & Temperament

Mystery Snails are peaceful creatures that spend most of their time exploring their surroundings and grazing on algae and other plant matter. They are not aggressive and can be kept with other peaceful fish species.

Male vs Female

Mystery Snails are hermaphrodites, meaning they have both male and female reproductive organs. However, they still require a partner to reproduce.

When mating, both snails will lay eggs, which will hatch in about two to four weeks.

In my experience, Mystery Snails are fascinating creatures to observe and can make a great addition to any aquarium. Just be sure to provide them with a healthy environment and proper care to ensure they thrive.

Tank Setup

Setting up a tank for your mystery snail is an important step in ensuring their health and happiness. Here are some key factors to consider:

Tank Size

When it comes to tank size, bigger is always better. A 10-gallon tank is the minimum size recommended for one mystery snail, but a larger tank will provide more room to explore and grow.

Keep in mind that mystery snails are active and curious creatures, so the more space they have, the happier they will be.


Mystery snails do not require any special lighting, but they do need a regular day/night cycle. A simple aquarium light on a timer is sufficient.

Filtration & Aeration

A good filtration system is essential for maintaining a healthy environment for your mystery snail. A hang-on-back filter or sponge filter is recommended.

Aeration is also important to ensure there is enough oxygen in the water. An air stone or bubbler can provide the necessary aeration.


Mystery snails are tropical creatures and require a water temperature between 68-82°F (20-28°C). A submersible aquarium heater is necessary to maintain a consistent temperature.


Mystery snails enjoy burrowing in the substrate, so a soft substrate such as sand or fine gravel is recommended. Avoid sharp or rough substrates that could damage their delicate foot.


Mystery snails enjoy having places to hide and explore, so adding decorations such as caves, driftwood, and rocks can provide them with stimulation and enrichment.


Live plants not only provide a natural aesthetic to the tank, but they also help maintain water quality by absorbing excess nutrients.

Mystery snails enjoy grazing on live plants, but be sure to choose plants that are safe for them to eat, such as java fern, java moss, and anubias.

Setting up a tank for your mystery snail may seem daunting, but with these key factors in mind, you can create a comfortable and stimulating environment for your shelled friend.

Water Quality

Proper water quality is essential for the health and well-being of your Mystery Snail. Here are some key factors to consider:

Water Temperature

The ideal water temperature for Mystery Snails is between 68-82°F. If the water is too cold, your snail may become inactive and sluggish.

If the water is too warm, it can cause stress and even death. Use a reliable thermometer to monitor the water temperature and make adjustments as necessary.

Water pH

Mystery Snails prefer slightly alkaline water with a pH between 7.6-8.4. However, they can tolerate a wide range of pH levels from 7.0-8.4. Avoid sudden changes in pH as this can cause stress and harm to your snail.

Water Hardness

Mystery Snails require moderately hard water with a hardness level of 150-250 ppm. Soft water can cause shell erosion and deformities.

Hard water with a high mineral content can also be harmful to your snail. Test your water regularly and make adjustments as necessary.

Water Changes

Regular water changes are crucial for maintaining good water quality. As a general rule, you should aim to change 25-50% of the water in your tank every 1-2 weeks.

This will help remove any accumulated waste and debris, as well as replenish essential minerals and nutrients.

When performing water changes, be sure to use a dechlorinator to remove any harmful chemicals or additives from your tap water.

Personally, I have found that keeping a consistent water change schedule has helped keep my Mystery Snails healthy and happy. I try to change 25% of the water in my tank every week, and I always make sure to test the water parameters before and after each change.

Tank Maintenance

Mystery snails are fairly easy to care for, but it’s important to keep their tank clean to ensure they stay healthy. Here are a few tips on tank maintenance:

First, make sure to perform regular water changes. You should aim to change 25% of the water in your tank every week. This will help keep the water clean and prevent the buildup of harmful bacteria.

Second, keep an eye on the water temperature. Mystery snails prefer water that’s between 68-82°F (20-28°C). You can use a heater to maintain a consistent temperature, but make sure to check it regularly to ensure it’s working properly.

Third, check the pH level of the water. Mystery snails prefer a slightly alkaline environment with a pH between 7.6-8.4. You can use a water testing kit to monitor the pH level and make any necessary adjustments.

Finally, make sure to clean the tank regularly. You should remove any uneaten food, dead plant matter, and waste from the tank as soon as possible. This will help prevent the buildup of harmful toxins in the water.

Personally, I like to do my water changes on Saturdays. I find it helpful to set a reminder on my phone so I don’t forget.

I also like to use a gravel vacuum to remove any debris from the bottom of the tank during water changes. It makes the process much easier!

Tank Mates

When it comes to keeping mystery snails, choosing the right tank mates is crucial for their health and well-being. Here are some factors to consider when selecting compatible tank mates:

Compatible Fish Species

There are plenty of fish species that can live harmoniously with mystery snails. Some of the most popular include:

  • Neon tetras
  • Platies
  • Guppies
  • Corydoras catfish

These fish are all peaceful and won’t bother your mystery snails. Plus, they won’t compete for food or resources.

Incompatible Fish Species

On the other hand, there are some fish species that should be avoided when keeping mystery snails. These include:

  • Cichlids
  • Bettas
  • Angelfish
  • Goldfish

These fish are known for being aggressive or nipping at the fins of other fish, which can stress out your mystery snails and even cause injury.

When it comes to mystery snails, it’s best to keep them in groups of two or more. This will help them feel more comfortable and secure in their surroundings.

However, be mindful of the size of your tank and the number of other fish you have. It’s important to avoid overcrowding, as this can lead to stress and health issues for all your aquatic pets.

Personally, I have found that keeping mystery snails with neon tetras is a great combination.

The neon tetras are small and peaceful, and they add a pop of color to the tank. Plus, they don’t bother the mystery snails at all. I highly recommend giving this combination a try!


Mystery snails are herbivores, which means they feed on plants. It is important to provide them with a balanced diet to keep them healthy and happy. Here’s everything you need to know about feeding your mystery snails.

What To Feed

You can feed your mystery snails a variety of foods, including:

  • Algae wafers
  • Spirulina flakes
  • Zucchini
  • Green beans
  • Lettuce

It is important to avoid feeding them meat or dairy products, as they cannot digest them properly.


You should feed your mystery snails once a day, and remove any uneaten food after a few hours. Overfeeding can lead to health problems, so make sure to only give them what they can eat in a few hours.


Here are a few tips to keep in mind when feeding your mystery snails:

  • Rotate their diet to ensure they are getting a variety of nutrients.
  • Provide them with calcium supplements, such as cuttlebone or crushed eggshells, to promote healthy shell growth.
  • Make sure to clean their food dish regularly to prevent the growth of harmful bacteria.

Remember, a healthy diet is key to keeping your mystery snails happy and thriving.

Personally, I have found that my mystery snails love zucchini the most. They will eagerly climb all over it and munch away until it’s gone!

Common Diseases


Mystery snails are relatively hardy creatures, but they are susceptible to a few common diseases. One of the most common diseases is Shell Rot, which is caused by poor water quality.

This disease causes the snail’s shell to become pitted and eroded, and can eventually lead to the death of the snail.

Parasites are another common problem for mystery snails. These can include worms, flukes, and other tiny organisms that can attach themselves to the snail’s body and cause damage.

If you notice your snail behaving strangely or see any unusual growths on its body, it may be a sign of a parasite infestation.


The symptoms of shell rot include a pitted or eroded shell, as well as a foul odor coming from the snail’s shell. Other symptoms may include lethargy, loss of appetite, and a lack of interest in its surroundings.

Parasite infestations can cause similar symptoms, as well as visible growths or deformities on the snail’s body.


If you suspect that your snail is suffering from shell rot or a parasite infestation, it’s important to take action immediately.

The first step is to improve the water quality in your tank. This can be done by performing regular water changes, testing the water regularly, and using a high-quality water conditioner.

You may also need to treat your snail with a medication designed to kill parasites or heal shell damage. Consult with a veterinarian or aquatic specialist for guidance on the best course of treatment.


The best way to prevent diseases in your mystery snail is to maintain a clean and healthy environment.

This means regularly cleaning the tank, performing water changes, and keeping the water quality within the appropriate range for your snail.

You should also avoid introducing any new fish or plants into the tank without first quarantining them to ensure they are free from disease.

Additionally, be sure to feed your snail a healthy and balanced diet, and avoid overfeeding or providing too much protein, as this can lead to health problems.

Personally, I’ve had to deal with shell rot in my mystery snail before, and it was a stressful experience. I learned the importance of maintaining good water quality and keeping an eye on my snail’s behavior and appearance to catch any potential problems early on.

Signs Your Mystery Snail is Sick

If you’re a new Mystery Snail owner, it can be difficult to tell if your snail is sick or not. Here are a few signs to watch out for:

  1. Inactivity: If your snail is not moving around as much as usual, it could be a sign of illness.
  2. Shell Damage: Cracks or holes in the shell can indicate a problem. While small chips and scratches are normal wear and tear, larger damage can be a sign of a bacterial infection.
  3. Discoloration: If your snail’s body or shell is a different color than usual, it could be a sign of illness.
  4. Odd Odors: If you notice a foul smell coming from your snail’s tank, it could be a sign of bacterial infection.

If you notice any of these signs, it’s important to take action quickly. Sick snails can deteriorate rapidly, and prompt treatment can be the difference between life and death.

Personally, I once noticed that one of my Mystery Snails was not moving around as much as usual. I quickly realized that the water temperature was too cold, and adjusted it accordingly. The snail perked up almost immediately, and I was relieved to have caught the problem before it became more serious.

Signs Mystery Snail is Dying

If you are a pet owner, you know how important it is to keep an eye on your pet’s health. The same goes for your mystery snail. Here are some signs that your mystery snail may be dying:

  1. The snail is not moving or responding to stimuli
  2. The snail is floating at the top of the tank or sinking to the bottom
  3. The snail’s shell is eroded or damaged
  4. The snail is not eating or has lost its appetite
  5. The snail’s body is discolored or has spots

If you notice any of these signs, it is important to take action immediately. The longer you wait, the less likely it is that your snail will recover.

I once had a mystery snail that started showing signs of illness. At first, I thought it was just a minor issue that would resolve on its own. However, I soon realized that the snail was not getting better.

I did some research and found out that the snail was suffering from a bacterial infection. I immediately took action and treated the snail with antibiotics. Thankfully, the snail made a full recovery.

The lesson here is that it is important to pay attention to your snail’s health and take action as soon as you notice any signs of illness. With proper care and attention, your mystery snail can live a long and healthy life.


Breeding Mystery Snails can be a fascinating experience for any aquarist. Here is what you need to know about breeding Mystery Snails.

Breeding Setup

To breed Mystery Snails, you will need a breeding setup that includes a separate breeding tank with a sponge filter, heater, and a substrate that is suitable for egg laying.

The breeding tank should be at least 10 gallons in size, and the water temperature should be maintained between 72-78°F.

How To Breed

Once you have set up the breeding tank, you will need to introduce a male and a female Mystery Snail. The male snail will typically have a more pointed shell, while the female will have a rounder shell.

You can tell the difference by looking at the opening of their shells. When the snails are ready to breed, the male will climb on top of the female and release sperm into the water.

The female will then lay her eggs on the substrate, which will hatch in about two weeks.


After the eggs hatch, the baby snails will need to be fed crushed algae wafers, blanched vegetables, and other suitable foods.

The water in the breeding tank should be kept clean and well-maintained, with regular water changes and testing to ensure the water parameters are suitable for the baby snails to thrive.

It is important to note that Mystery Snails can breed quickly and produce large numbers of offspring. Make sure you have a plan in place for what to do with the babies, as they can quickly outgrow their tank.

I remember when I first bred my Mystery Snails. I was so excited to see the tiny eggs hatch into baby snails. It was amazing to watch them grow and develop over time.

With the right setup and care, breeding Mystery Snails can be a rewarding experience for any aquarist.
