Whether you are a beginner looking to add mystery snails to your aquarium or an experienced snail keeper wanting to expand your knowledge, this guide will provide valuable insights into the reproductive behavior of these captivating creatures.

By the end, you will have all the information you need to ensure the successful reproduction and care of mystery snails in your tank. 

Where do mystery snails lay their eggs clutch?

Mystery or apple snails lay their eggs above the water line in a calcareous clutch. They typically search for a dry surface above the water level, such as the underside of a tight-fitting lid or the top edge of the aquarium.

The mother snail will lay a cluster of eggs, which are typically pink and resemble small grains of rice.

These clutches can contain dozens of eggs, depending on the size and age of the snail. The eggs will eventually hatch into tiny snails, then drop into the water and begin their life cycle.

Aquarium owners need to check for these clutches regularly and either remove them or ensure the water level in the tank is low enough to prevent the baby snails from hatching.

Overall, mystery snails are fascinating creatures to observe in a home aquarium, and their unique reproduction habits add to their intrigue. 

How Do Mystery Snails Reproduce in Aquarium?

Mystery snails reproduce in aquariums through a process called sexual reproduction. The male snail will fertilize the female’s eggs by depositing sperm into a sac near her reproductive organs.

The female will then lay eggs on hard surfaces such as aquarium glass or decorations above the waterline. The eggs are enclosed in a gelatinous mass and will hatch in about 2 to 4 weeks, depending on water conditions.

It’s crucial to maintain proper water parameters and provide enough food for the snails during this time to ensure the successful development of the eggs. Once hatched, the baby snails will drop into the water and begin feeding on algae and uneaten fish food.

Apple snails can breed quite readily in aquariums, so you must be prepared for potential population growth if you have both male and female snails in the tank. 

Can mystery snails lay eggs without a mate?

Yes, mystery snails can lay eggs without a mate, but there’s a catch: the eggs will be infertile. This means they won’t hatch into baby snails.

Here’s what you need to know:

  • Mystery snails are not asexual: They have separate sexes, male and female, and require fertilization for successful reproduction.
  • Females can store sperm: Even after mating with a male, a female can store sperm for several months and lay multiple eggs using the stored sperm.
  • Unmated females can still lay eggs. However, these eggs will not be fertilized and will eventually dry out and die.

If you see your mystery snail laying eggs but don’t have a male in the tank, you can:

  • Leave the eggs: They won’t harm your tank and will eventually dry out and disappear.
  • Remove the eggs: If you find them unsightly, you can gently scrape them off the tank surface and discard them.
  • Introduce a male: Add a male snail to your tank if you want baby snails. Just make sure your tank can handle the increased bioload.

How Do Mystery Snails Mate?

Mystery snails, also called apple snails, are hermaphrodites, meaning they have both male and female reproductive organs. Freshwater snails engage in a unique and fascinating process when it comes to mating. They start by releasing pheromones into the water to signal their readiness to mate.

Once a suitable mate is found, the snails will engage in a courtship display, which involves swirling and touching each other with their tentacles. Eventually, the snails will align their bodies and exchange sperm with each other.

After mating, mystery snails will lay their eggs above the waterline on a hard surface, such as an aquarium glass or a plant leaf. It takes about two weeks for the eggs to hatch, and the baby snails will then drop into the water and start their life cycle.

Inca snails have a fascinating and intricate mating process demonstrating their unique reproductive capabilities as hermaphrodites. 

Will mystery snails eat baby snails?

Mystery snails are typically peaceful creatures and are not known to hunt or eat their offspring actively. While they may exhibit some scavenger behavior and consume dead plant matter or decaying food, they are unlikely to prey on baby snails intentionally.

However, it is worth noting that snails have a reputation for being voracious eaters and will consume just about any plant matter they come across. Therefore, if there is not enough food to sustain the adult snails, they may consume their young as a last resort.

Additionally, if the baby snails are tiny, there is a chance that the mystery snails could accidentally ingest them while foraging for food. It is always best to provide sufficient vegetation and other food sources for snails to mitigate any potential risk of them eating their offspring. 

Male vs Female Mystery Snails

A few physical characteristics can distinguish male and female mystery snails. Males tend to have a slightly longer and more slender shell, while females have a rounder, wider shell.

Another way to identify the gender of these snails is by observing their reproductive organs. Males have a penis sheath located on the right side of their body, while females have a reproductive opening called a genital pore on the right side. Additionally, female mystery snails are typically larger than males.

Both genders make great additions to aquariums, as they are peaceful and enjoyable to watch. Whether male or female, mystery snails can thrive in freshwater environments and help keep the tank clean by grazing on algae. 

Here is a comparison of male vs female mystery snails:

Physical Differences:

  • Shell Opening: The most reliable way to tell the sex of a snail is by looking at the opening of its shell. Male mystery snails have a rounder shell opening, while female mystery snails have a more oval-shaped opening. This is to accommodate the male’s penis, which is located on the right side of the body. 
  • Penis Sheath: Male mystery snails have a visible penis sheath, which is a white, fleshy protrusion located on the right side of their body, just above the gills. Females do not have a penis sheath. 
  • Shell Translucency: As female mystery snails mature, their shells often become more translucent, especially at the tip of the spire. This is because they are storing eggs inside their bodies. Males’ shells typically remain opaque throughout their lives. 


  • Mating: If you witness your apple snails mating, it is easy to tell which is male or female. The male will mount the female and insert his penis into her shell opening. 

Other Methods:

  • Size: Male mystery snails are typically slightly smaller than female mystery snails. However, this is not reliable for sexing young snails, as they all start pretty small.
  • Number of Holes: Some people believe that you can sex mystery snails by counting the number of holes in their shells. However, this method is not accurate, as both males and females have one hole in their shells.

It is important to note that these are just general guidelines, and there can be some variation between individual snails. If you are having trouble sexing your mystery snails, it is best to consult a qualified aquarist.

How to Breed Mystery Snails: Mystery Snail Breeding & Hatching for Beginners

Mystery snail breeding and hatching can be a fascinating hobby for beginners. To start, you’ll need a male and female snail, which can be identified by the shape and size of their strong shells.

These snails are hermaphrodites, meaning they have both male and female reproductive organs, so any two mystery snails can potentially mate and produce offspring.

After mating, the female will lay eggs above the water line, typically on the aquarium glass or other hard surfaces. Keeping the water temperature and quality stable during this time is essential to ensure successful hatching.

After about 2-4 weeks, the eggs will hatch, and the young snails will begin to explore their new environment. It’s crucial to provide plenty of algae and other plant matter for the baby snails to eat and a stable environment with clean water.

With proper care and attention, breeding and hatching can be a rewarding experience for beginners looking to expand their aquarium hobby.
