Will Mystery Snails Climb Out of Tank?

Mystery snails have been known to climb out of tanks, especially if the water quality is poor or insufficient food is available. They are natural explorers and may try to escape if they feel stressed or unhappy in their environment.

It is important to regularly check the water parameters and ensure that the tank is securely covered to prevent any escape attempts.

How Long Do Mystery Snails Live

Providing a healthy and stimulating environment for mystery snails, including plenty of hiding spots, vegetation, and a balanced diet, can help reduce the likelihood of them trying to climb out.

Keeping the water levels in the tank high enough can also discourage escape attempts. If mystery snails do manage to climb out of the tank, it is important to carefully place them back into the water as soon as possible, as they can quickly become dehydrated and die if left out of the water for too long. 

There are several reasons why mystery snails might climb out of their tank, but the most common ones are:

  1. Poor water quality: Mystery snails are sensitive to changes in water quality, and if the ammonia, nitrite, or nitrate levels in their tank are too high, they may try to escape in search of better conditions. If necessary, you can test your water quality with a home testing kit and do a partial water change. 
  2. Lack of food: Mystery snails are omnivores that eat algae, biofilm, residue, and some plants. They may try to find food elsewhere if they need more food in their tank. You can supplement their diet with blanched vegetables, sinking fish food pellets, or algae wafers. 
  3. Overcrowding: If your tank is overcrowded, there may be more food or space for all the snails. This can lead to competition and stress, which may cause some snails to try to escape. Ensure your tank is properly sized for the number of snails you have.
  4. Aggressive tankmates: Mystery snails are peaceful creatures, but if other fish harass them in the tank, they may try to escape. Before adding them together, ensure your tank mates are compatible with mystery snails.
  5. Curiosity: Mystery snails are curious creatures who may sometimes climb out of their tank to explore their surroundings. This is usually not a cause for concern, but if you’re worried about them escaping, you can add a lid to your tank.

If you’re concerned about your mystery snails climbing out of their tank, it’s important to identify the root cause of the problem and take steps to fix it. Doing so can help ensure that your snails stay happy and healthy.

NOTE: Leave 1-2 inches above the waterline for adventurous mystery snails! They might climb to breathe or lay their eggs.

How Long Can Mystery Snails Live Out of Water?

While mystery snails can survive outside of water for some time, it’s crucial to remember that water is their natural habitat, and staying out for too long can be detrimental, even fatal. Here’s a breakdown of their survival time and important factors to consider:

Survival duration:

  • Short-term: In ideal conditions, mystery snails can survive several days out of water. This varies depending on factors like size, humidity, and temperature.
  • Long-term: Extended periods outside of water are not recommended. Staying out for more than a week significantly increases the risk of death due to dehydration, suffocation, or shell damage.

Important factors:

  • Operculum: Mystery snails have a trapdoor-like structure called an operculum that they seal their shell with when out of water. This helps conserve moisture and prevent them from drying out completely.
  • Size: Larger snails generally have more reserves and can last longer outside water than smaller ones.
  • Humidity: Higher humidity levels help retain moisture and extend their survival time.
  • Temperature: Cooler temperatures slow down their metabolism and can slightly extend their survival time. However, avoid exposing them to extreme temperatures.


  • Even if your mystery snail appears alive after being out of water for a while, it may have suffered internal damage or stress.
  • It’s best to avoid keeping them out of water for extended periods. If you find your snail outside its tank, return it to the water immediately.
  • Maintain good water quality and parameters in their aquarium to create a healthy, thriving environment that minimizes their need to venture out.

Understanding their limitations and providing proper care can help your mystery snails live long and healthy lives within their aquatic habitat.

How to Keep Snails from Crawling Out of Aquarium

To keep snails from crawling out of your aquarium, you can try a few strategies. First, ensure the water quality in the tank is good, as snails may try to escape if the conditions are unsuitable.

Additionally, you can create a barrier around the top of the tank using a fine mesh or plastic screen to prevent the snails from getting out.

Another approach is to lower the water level slightly to make it harder for the snails to reach the top and escape. You can also add more plants and hiding spots in the aquarium to encourage the snails to stay inside.

Lastly, be mindful of overfeeding, as excess food can attract snails to the surface in search of more food. By implementing these strategies, you can help ensure your snails stay safely inside their aquarium.
