  • Egg Clutch Appearance: Mystery snails lay their eggs above the waterline, typically on the walls of the aquarium, decorations, or even on the aquarium lid. The eggs are laid in clusters that resemble small bubbles. These clusters are usually round and range in color from pale pink to brown. They are about the size of a pea or slightly larger.
  • Hatching Time: The eggs of mystery snails are relatively hardy and can withstand a certain degree of drying out. This is why they’re laid above the waterline. The hatching time can vary based on factors like temperature, humidity, and water conditions. It typically takes around 2 to 4 weeks for the eggs to hatch. During this time, the eggs may change color and become darker.
  • Hatching Process: When the eggs are ready to hatch, the tiny snails will emerge from the egg mass. They often drop into the water below and begin their life in the aquatic environment. It’s important to ensure that there is a way for the baby snails to safely drop into the water, as they can be harmed if they fall from too great a height.
  • Caring for Baby Snails: Once the baby snails have hatched and are in the water, they will need suitable food and a safe environment. Providing algae, plant matter, and specialized snail or algae wafers can help them grow. Ensure that water parameters are suitable for their growth and that they have plenty of hiding spots to avoid being eaten by larger tank inhabitants.
  • Population Control: Mystery snails are known for their prolific breeding habits, and if conditions are right, they can lay numerous egg clutches. If you don’t want a large population of mystery snails in your aquarium, you can manually remove and dispose of egg clutches. Be sure to handle the eggs gently, as they are delicate and can be easily damaged.
  • Sexual Dimorphism: Mystery snails are gonochoristic, meaning they have separate sexes. However, it can be difficult to distinguish between male and female snails based on external appearance alone. Males tend to have a slightly smaller and more pointed aperture (opening) compared to females. In some cases, females might appear larger due to their rounder shells, but this isn’t a foolproof method of sex determination.

Food and Diet

Mystery snails are primarily herbivores, and their diet consists mainly of plant matter and algae. Providing a balanced and nutritious diet is essential for their health and well-being. Here are some food options for mystery snails:

  • Algae and Vegetation: Mystery snails love to graze on algae and various types of aquatic plants. Make sure your aquarium has a good supply of live plants, as well as surfaces with algae growth. This will allow the snails to naturally graze and forage for their food.
  • Algae Wafers: Algae wafers are commercially available snail food that provide a concentrated source of plant matter and nutrients. These wafers are designed to sink, allowing snails to feed on them. Look for high-quality algae wafers with a variety of plant-based ingredients.
  • Blanched Vegetables: You can offer blanched (briefly boiled and then cooled) vegetables to your mystery snails. Vegetables like zucchini, spinach, lettuce, and cucumber are good options. Attach a vegetable slice to a feeding clip or weigh it down with a small rock, so it stays submerged in the water.
  • Spirulina Pellets: Spirulina-based pellets are another suitable option for mystery snails. Spirulina is a type of algae rich in nutrients and is often used in fish and invertebrate diets.
  • Calcium Sources: Mystery snails require calcium to maintain healthy shell growth. Providing a source of calcium is important. You can use cuttlebone (a natural source of calcium) or specialized calcium supplements designed for snails and crustaceans.
  • Avoid Overfeeding: While mystery snails have a hearty appetite, it’s important not to overfeed them. Excess food can lead to water quality issues and contribute to algae blooms. Feed only as much as they can consume within a few hours, and remove any uneaten food promptly.
  • Variety: Like all animals, variety in their diet is beneficial. Try to offer a mix of fresh vegetables, commercial snail food, and natural algae sources to ensure they receive a balanced diet.

Lifespan of Mystery Snails

The lifespan of mystery snails (Pomacea diffusa), also known as apple snails, can vary based on a range of factors, including their environment, care, genetics, and overall health. On average, mystery snails can live anywhere from 1 to 3 years in captivity, although some individuals may live longer under optimal conditions.

Factors that can influence the lifespan of mystery snails include:

  • Water Quality: Good water quality is crucial for the health and longevity of mystery snails. Ammonia, nitrite, and nitrate levels should be kept in check, and regular water changes are essential.
  • Diet: Providing a balanced and nutritious diet is important. A diet rich in plant matter, algae, and calcium sources (for shell health) contributes to the overall health of the snails.
  • Tank Size: The size of the aquarium matters. In a larger, well-maintained tank with ample space and resources, mystery snails tend to thrive better.
  • Temperature and Humidity: Mystery snails are tropical animals, so maintaining the appropriate water temperature and humidity levels is important. Keep the water temperature within the range of 68°F to 82°F (20°C to 28°C).

Foul Odor: A strong, foul odor coming from the snail might indicate decay and death.

No Movement: Gently touch the snail’s foot or the operculum (the trapdoor-like structure covering the shell opening). If there’s no response or movement after a few days, it might be a sign of death.

Shell Odor: If the shell has a bad odor, it could indicate that the snail has died and begun to decompose.

Discoloration: If the snail’s body appears discolored, dried out, or shriveled, it could be a sign of death.

Floating: If the snail is floating at the water’s surface and doesn’t show any signs of moving or attempting to right itself, it could be a sign of death. However, note that snails can sometimes float temporarily due to air trapped in their shell, so this isn’t always a definitive sign of death.

Shell Decay: If you notice the snail’s shell becoming eroded, pitted, or significantly damaged, it could be a sign of deterioration and death.

Lack of Response: Live mystery snails will usually respond to gentle stimuli, such as tapping on the shell or touching the foot. If there’s no response over an extended period, it could indicate that the snail is dead.

Unraveling the Enigmatic Allure of Mystery Snails Floating

Why is mystery Snail floating?

  • Air Trapped in Shell: Mystery snails have a trapdoor-like structure called the operculum that covers their shell opening. Sometimes, air can get trapped inside the shell, causing the snail to float. This is usually temporary and not a cause for concern. The snail should eventually release the trapped air and sink back to the bottom.
  • Feeding or Grazing: Mystery snails often float to the water’s surface to feed on surface films or algae. This behavior is normal and usually temporary.
  • Newly Introduced Snail: When a mystery snail is introduced to a new environment, it might float temporarily as it adjusts to the water conditions. This behavior can last for a short period as the snail acclimates.
  • Shell Damage or Shell Erosion: If a mystery snail’s shell is damaged or eroded, it might affect its buoyancy. In some cases, shell damage can lead to air becoming trapped, causing the snail to float.
  • Water Parameters: Poor water quality, fluctuations in water temperature, or imbalances in water chemistry could stress the snail and cause it to float. Make sure your tank’s water parameters are within the appropriate range for mystery snails.
  • Illness or Stress: If your mystery snail is sick or stressed, it might exhibit abnormal behavior, including floating. Observe its overall condition and behavior for any signs of illness, such as changes in color, lethargy, or loss of appetite.
  • Dead Snail: If a mystery snail has died, it might float at the water’s surface. As the body decomposes, gases can build up inside the shell, causing it to become buoyant. Check for other signs of death, such as a foul odor or lack of response to stimuli.
  • Inadequate Calcium: Mystery snails require calcium for healthy shell growth. A lack of calcium can result in weak or thin shells, which might affect buoyancy.

If your mystery snail is floating, closely monitor its behavior and overall health. If the floating persists or is accompanied by other concerning signs, such as changes in color, foul odor, or prolonged inactivity, it’s a good idea to investigate further and address any potential issues. Regular water testing, proper diet, and a suitable tank environment are important factors in maintaining the well-being of your mystery snail.

How to tell if mystery snail eggs are fertile?

Determining whether mystery snail eggs are fertile can be challenging, as the process requires observation over time. Fertile eggs will develop into baby snails, while infertile eggs will remain unchanged or deteriorate. Here are some signs to help you determine if mystery snail eggs are fertile:

  • Color Changes: Fertile mystery snail eggs might darken or change in color over time as the embryos inside develop. However, the color change can be subtle and may not always be a reliable indicator.
  • Egg Development: Watch for changes in the appearance of the egg cluster. Over time, fertile eggs will become more opaque and less translucent as the embryos grow. Infertile eggs might remain clear and unchanged.
  • Texture: As fertile mystery snail eggs develop, they might become more solid and less gelatinous. Infertile eggs could remain soft and jelly-like.
  • Egg Movement: In some cases, you might notice tiny movements within the egg mass as the embryos develop. However, this can be difficult to observe, and not all eggs will exhibit this movement.
  • Hatching: The most definitive sign of fertile eggs is the hatching of baby snails. If the eggs are fertile, you’ll eventually see small snails emerging from the egg clusters. This process usually takes around 2 to 4 weeks after the eggs are laid.
  • Appearance of Eyespots: Some people report seeing small, dark spots that resemble eyes on the developing embryos inside the eggs. These spots can indicate that the eggs are fertile, but not all fertile eggs will display this feature.
  • Egg Condition: Infertile eggs might become discolored, break down, or develop mold over time. Fertile eggs tend to maintain their structure and remain intact until they hatch.

Remember that it can be challenging to determine egg fertility with absolute certainty, and some signs might be subtle or not consistently present. If you’re interested in breeding mystery snails and are observing egg clusters, it’s a good practice to be patient and observe the eggs over time. If the eggs remain unchanged or start deteriorating, they might be infertile. If you notice baby snails hatching from the eggs, that’s a clear indication of fertility.

Keep in mind that mystery snails are often prolific breeders, and a single clutch of eggs can result in a significant number of baby snails. Be prepared to provide suitable care for the baby snails if you decide to allow them to hatch and grow in your aquarium.
