Mystery Snail Basics

Origins and Natural Habitat

Mystery snails originate from South America, specifically in countries such as Brazil, Argentina, and Paraguay. They naturally inhabit freshwater rivers, ponds, and swamps, which provide them with a diverse environment. In these habitats, they find plenty of food sources, such as plants, algae, and debris.

Size and Shape

Mystery snails have a round, spiral-shaped shell. Their shells can grow up to 2 inches in diameter, depending on the species and availability of food. The shells have a distinctive ‘trapdoor’ called an operculum, which helps protect the mystery snail from predators when they retract into their shell.

Color and Markings

The color and markings of mystery snails vary significantly between species. Some common colors include:

  • Gold: Golden-yellow shell with a white body
  • Blue: Light blue shell with a dark blue or black body
  • Ivory: Creamy white shell with a white body

There are also species with unique patterns such as black stripes or spots on their shells.


Mystery snails live an average of 1 to 2 years in a well-maintained aquarium. Providing them with proper water conditions, temperature, and diet will help ensure a healthy and long life for your friendly snails.

Diet and Feeding

Mystery snails primarily feed on plants and vegetation, including algae. In your aquarium, they will actively search for algae and vegetation to consume. To keep them healthy and happy, ensure there is enough naturally occurring algae in the tank for them to feed on. Smooth surfaces and plants in the tank serve as ideal areas for algae to grow.

It’s essential to maintain a balanced diet for the well-being of your mystery snails. In addition to the algae they find in the tank, consider supplementing their diet with algae wafers and sinking pellets or flakes. Feeding them vegetables, such as kale, spinach, zucchini, and cucumber, is also beneficial.

While providing a variety of foods will ensure your snails receive proper nutrition, avoid having an excess of algae and plant matter, as it can negatively impact water quality. Finding the right balance and offering a diverse diet will lead to healthy, thriving mystery snails in your aquarium.

Behavior and Temperament

Mystery snails are peaceful creatures that tend to mind their own business. They are not interested in or aware of the activities happening in the rest of the tank. As you observe them, you’ll notice how they maintain their focus and resilience, getting back to work after being startled.

When mystery snails perceive a threat, they retreat into their shell until the danger passes. To help them feel safe and stress-free, it’s essential to follow recommended tank mate choices, which helps avoid realistic sources of danger for your snails.

These fascinating creatures are dedicated to their task of searching for algae and plant matter to eat. Surprisingly fast in their movements within the aquarium, mystery snails travel efficiently while maintaining their friendly and relaxed character.

Occasionally, you might notice your mystery snails floating in the water. It usually isn’t a cause for concern. However, prolonged floating may indicate sickness or imminent death, and this should be monitored closely to ensure the wellbeing of your mystery snail.

Care and Tank Requirements

Tank Size

Mystery snail care requires consistency and attention to their habitat. For one snail, the minimum tank size is five gallons. If you wish to keep additional snails, you should add an extra five gallons of space for each to avoid overcrowding.

Water Parameters

Monitoring water parameters closely is essential for the well-being of mystery snails. Keep the water temperature between 68°F and 82°F. Maintain pH levels within a range of 7.0 to 7.5, and water hardness should be between 5 and 15 dGH. Since copper is harmful to mystery snails, avoid it in the water.

Tank Setup and Decorations

Including plants in your snail’s tank is essential as they spend most of their time scavenging for plant matter. Opt for hardy plants like Hornwort, Java moss, and Anubias Barteri to enhance their environment. It’s possible to include a variety of substrate materials, but ensure that it’s not too coarse and complements the plants.

Adding rocks to the aquarium is a great idea as it provides surfaces for algae growth, keeping your snails engaged. Remember, mystery snails are slow-moving creatures that require care and attention.

Filtration and Aeration

Regular testing of water parameters is necessary to maintain a healthy environment for your mystery snails. Providing the right amount of calcium is crucial for their shell health, and feeding them calcium-dense veggies helps cater to this need. Avoiding copper contamination in the water is also vital to their well-being. To ensure proper filtration and aeration, invest in a suitable filter that keeps the water clean and well oxygenated in your snail’s home.

Suitable Tank Mates

Mystery snails can peacefully live with a wide range of freshwater fish in your aquarium. When choosing tank mates, you should consider fish species that are neither aggressive nor have a natural diet that preys on snails. As mystery snails are passive and nonintrusive, they can easily coexist with other fish.

Some common mystery snail tank mates include:

  • Tetras
  • Killifish
  • Cory catfish
  • Otocinclus
  • Nerite snails
  • Ghost shrimp
  • Amano shrimp
  • Red cherry shrimp

Moreover, betta fish and mystery snails can also share an aquarium successfully. They tend to coexist peacefully without bothering each other. An added benefit of having these snails in your tank is that they help clean up the environment, providing a healthier habitat for your betta fish. Clear water is crucial for your aquarium’s inhabitants, and with mystery snails, this is more achievable.

To maintain a harmonious environment, remember that proper tank mate selection is essential. By following these guidelines and selecting compatible tank mates, you are ensuring a thriving and peaceful home for your mystery snail.


Breeding mystery snails is a straightforward process that you can manage regardless of your experience level. To start breeding, you need a male and female snail in the same tank. Determining their sex can be challenging, but observing mating behavior is a reliable method.

No special adjustments to the tank or water parameters are necessary for breeding mystery snails. Females will lay their eggs near the water’s surface in a distinct cocoon. Observing the egg-laying process can be fascinating and rewarding for you.

The eggs will incubate for a few weeks before hatching. The baby snails do not require any special care as they are capable of self-sufficiency. Breeding mystery snails can be a rewarding experience for aquarium enthusiasts like yourself.

Common Diseases and Treatments

Mystery snails are sensitive to water quality, and even mild shifts in parameters can negatively impact their health. Monitoring your snail regularly is essential to identify changes in behavior or appearance that may indicate health issues.

Poor water quality can lead to parasites, which are challenging to treat and have the potential to cause the death of your snail. Maintaining top-notch water quality and avoiding contamination in the tank is crucial for the snail’s well-being.

Copper in the water can be fatal, as it is toxic to invertebrates like mystery snails. Be mindful of the copper content in your snail’s environment, and take steps to ensure their safety.

Illnesses can cause deformities and irregular shell growth in mystery snails. Pay attention to any changes in your snail’s shell or behavior, such as remaining motionless for extended periods. A motionless snail is likely experiencing a health problem that needs to be addressed.

While the absence of specific diseases in mystery snails is positive, it’s essential not to overlook their sensitivity toward water quality. As an owner, taking proper care can help your snail live a long and healthy life.
