So, let’s delve into the world of mystery snails and uncover the secrets of their survival outside of water. 

Can Mystery Snails be kept in the fish tank?

Yes, Mystery snails can be kept in a fish tank. They are peaceful creatures that do well in community tanks with other non-aggressive tank mates.

Mystery snails are also relatively easy to care for, requiring a tank with a lid to prevent them from leaving the water environment. They can tolerate a wide range of water parameters, but keeping the water clean and well-maintained is essential to ensure their health and longevity.

Overall, Mystery snails are a popular and beneficial addition to freshwater aquariums, bringing a practical and visual appeal to the tank. 

Mystery snails (also known as trumpet snails) appearing seemingly out of nowhere in your aquarium can be surprising, but there are several possible explanations:

1. Hitchhikers: Mystery snails are prolific hitchhikers. They can attach to plants, decorations, or even fish you bring home from the pet store, inadvertently introducing them to your tank. They can also lay eggs on these items, which hatch later, seemingly appearing out of nowhere.

2. Long-lived eggs: Mystery snail eggs are hardy and can remain dormant, waiting for the right conditions to hatch. If you recently changed your tank setup or introduced new plants, this could trigger the eggs to hatch, giving the impression of new snails appearing.

3. Nocturnal activity: Mystery snails are primarily nocturnal, hiding during the day and venturing out at night to feed. You might not notice them for a while and then suddenly see them when they’re more active.

4. Livebearers: While most mystery snails lay eggs, some types of snails are livebearers, dropping fully formed baby snails. This can explain a sudden increase in the snail population without noticeable eggs beforehand.

5. Accidental release: If you have other tanks with mystery snails, you might accidentally transfer them to a different tank during water changes or maintenance.

Important Note: Mystery snails can become an issue if your tank is overcrowded or has aggressive fish that might prey on them. While they can be helpful algae eaters, it’s crucial to maintain a balanced ecosystem.

Some experts suggest that adult mystery snails can survive out of water for about 1-2 days, while others claim they can last up to a week under the right conditions.

It’s important to note that the temperature and humidity levels of the surrounding environment play a critical role in how long a mystery snail can live out of water. It’s always best to keep mystery snails in a moist environment to ensure their health and wellbeing.

While mystery snails can survive out of water for some time, it’s not an ideal situation and not something you should intentionally do. Here’s what you need to know:

Survival Time:

  • Days:¬†Mystery snails can survive¬†several days¬†out of water thanks to their operculum, a trapdoor-like lid that seals their shell and helps retain moisture.
  • Factors:¬†The survival time depends on factors like¬†temperature, humidity, and overall health. Warmer temperatures and dry environments will shorten their lifespan outside of water.

What Are the Water Conditions That Mystery Snails Need?

Mystery snails require specific water conditions to thrive. They prefer slightly alkaline water with a pH level between 7 and 8 and a water hardness of 12-15 dGH. The temperature should be between 65-82¬įF (18-28¬įC) to maintain a comfortable environment for the snails.

It is also essential to ensure the water is adequately filtered and free from ammonia and nitrites, as these can harm the snails.

Additionally, mystery snails need access to calcium to maintain healthy shell growth, so it is beneficial to include sources of calcium in their diet, such as cuttlebone or calcium-rich vegetables.

Providing the correct water conditions for mystery snails is essential for their overall health and wellbeing, and maintaining a suitable aquatic environment will help them live a long and happy life in captivity. 

What Conditions Allow the Mystery Snail to Live Outside of Water?

While mystery snails can survive for some time outside of water, it’s important to remember that they are aquatic creatures and thrive in water environments. Prolonged periods outside of water can be stressful and even fatal for them. Here’s what you need to know:

Limited ability to live outside water:

  • Lungs:¬†Mystery snails possess both gills and lungs, allowing them to breathe air for short periods when necessary. This adaptation helps them survive brief emergencies like escaping predators or navigating between bodies of water during floods.
  • Operculum:¬†When out of water, they seal their shell with a trapdoor-like structure called an operculum, conserving moisture and preventing desiccation.

Conditions for short-term survival:

  • Humidity:¬†The critical factor for survival outside water is¬†high humidity. Ideally, they need an environment with at least¬†70-80% humidity¬†to prevent drying out.
  • Time:¬†Even in high humidity, they can only survive for¬†limited periods¬†outside water. The exact duration depends on factors like size, health, and temperature, but it‚Äôs generally¬†not recommended to exceed 24 hours.

Signs of distress:

  • Prolonged emergence:¬†If your mystery snail stays out of water for extended periods, it‚Äôs a sign of potential problems in the tank.
  • Shell damage:¬†Dryness can damage their delicate shells, so be mindful of cracks or chips.
  • Lethargy:¬†A sluggish or inactive snail could indicate stress from being out of water.


  • Mystery snails are aquatic creatures:¬†While they can tolerate short periods outside water, their long-term wellbeing depends on a clean, well-maintained aquarium environment.
  • Focus on creating optimal water conditions:¬†Ensure proper water parameters like temperature, pH, hardness, a good diet, and ample hiding places.
  • Minimize time outside water:¬†If you find your snail outside the tank, gently return it to the water as soon as possible.

By understanding their needs and providing a suitable aquatic environment, you can ensure your mystery snail thrives and lives a longer period healthy.
