The Appearance of Mystery Snails (Pomacea bridgesii)

Mystery snails are known for their striking appearance, with their large, round shells and vibrant colors. Their shells can come in various shades, including blue, gold, purple, and even a combination of these colors.

The snail’s shell often has intricate patterns and can be translucent or opaque. The snails have a soft, fleshy body and a long, retractable siphon for breathing and sensing their environment. Their tentacles also add to their unique appearance, with one pair being longer and thinner while the other is shorter and thicker.

Mystery snails also known for their slow and graceful movements, which can add to their mysterious and captivating presence in a home aquarium. Their appearance makes them a popular choice for hobbyists and aquarists who appreciate the beauty of these unique creatures. 

Mystery snails have the ability to breathe air through their gills and via a tube that extends from the front of their bodies. They raise this tube above the water line, moving it back and forth to draw in air.

How to Set Up an Aquarium for Mystery Snails

Setting up an aquarium for mystery snails is a fun and rewarding project. These charming little creatures are relatively easy to care for, making them an excellent choice for beginner aquarists. Here’s a step-by-step guide to get you started:

1. Choose your tank:

Mystery snails only require a little space but need room to roam and graze. A 5-gallon tank is the minimum recommended size for one or two snails. For each additional snail, add another 3 gallons of capacity.

2. Set up the substrate:

Snails like to burrow and explore, so choose a smooth, rounded substrate that won’t damage their delicate shells. Gravel or small pebbles are ideal. Avoid sharp sand or crushed coral, as these can be irritating. Rinse the substrate thoroughly before adding it to the tank.

3. Add decorations and plants:

Decorations provide hiding spots and climbing surfaces for your snails. Choose aquarium-safe decorations made of natural materials like rocks, driftwood, or ceramic. Live plants are also beneficial, as they help oxygenate the water and provide snail food. Opt for hardy aquarium plants like Anubias, Java fern, or Amazon sword.

4. Fill the tank with water:

Use treated tap water or spring water that has been dechlorinated. Aim for a temperature between 70-78°F (21-26°C).

5. Cycle the tank:

Cycling the tank is essential for establishing healthy bacteria to break down waste products. This typically takes 4-6 weeks. A water testing kit can monitor ammonia, nitrite, and nitrate levels throughout the cycling process.

6. Add your snails:

You can introduce your mystery snails once the tank is cycled and water parameters are stable. Acclimate them slowly to the new water temperature by floating the bag they came in in the tank for 15-20 minutes. Then, gently release the snails into the water.

7. Feed your snails:

Mystery snails are omnivores who eat various foods, including algae, biofilm, sinking fish food, blanched vegetables, and even cucumber. Avoid overfeeding, as this can lead to water quality problems.

8. Maintain the tank:

Perform regular water changes (10-20% of the water every week) and siphon out any waste. Test the water parameters regularly and adjust them as needed.

With proper care, your mystery snails can thrive in your aquarium for many years. They’re fun to watch and add a touch of personality to any tank.

Here are some additional tips for setting up a mystery snail aquarium:

  • Keep the lid on your tank to prevent your snails from escaping.
  • Avoid using copper-based medications or algae treatments, as these can harm snails.
  • If you want your snails to breed, provide them with a flat surface above the waterline where they can lay their eggs.

Mystery Snail Caring Tips

Mystery snails are popular for aquarium enthusiasts due to their peaceful nature and exciting behavior. When caring for these unique creatures, remember a few crucial tips.

First and foremost, providing them with a proper environment is crucial. This includes a tank of at least 5 gallons with a stable water temperature and various hiding spots. Mystery snails are herbivores, so they thrive on a diet of algae, vegetables, and commercial snail food.

It’s essential to avoid overfeeding them, as this can lead to water contamination and health issues. Regular water changes and tank maintenance are also vital for keeping mystery snails healthy. 

Additionally, watch for signs of illness or distress and seek veterinary help. With the proper care and attention, mystery snails can make a delightful and low-maintenance addition to any aquarium. 

Warning: Be cautious about using tap water in your tank if you have snails, as they are susceptible to copper. It’s essential to ensure adequate calcium in their water to maintain the health of their shells. You can achieve this by feeding them calcium-rich foods like kale, spinach, and other greens, placing a cuttlebone in the water, or using calcium additives.

Best Tank Mates for Mystery Snails

Choosing suitable tank mates for your Mystery snails is crucial for their well-being and creates a harmonious aquarium environment. Here are some good and bad choices to consider:

Good Tank Mates:


  • Peaceful Community Fish: Neon tetras, rasboras, guppies, danios, cherry barbs, platys, honey gouramis, corydoras catfish, kuhli loaches, otocinclus catfish. These fish are too small or too peaceful to bother your snails.
  • Shrimp: Amano shrimp, ghost shrimp, cherry shrimp, and other dwarf shrimp add color and movement to the tank while acting as excellent algae eaters. They co-exist peacefully with snails.

Other Snails:

  • Nerite Snails: These hard-shelled snails are herbivorous and don’t compete with Mystery Snails for food.
  • Rabbit Snails: They’re peaceful algae eaters with unique looks, making them exciting tank mates.

Bad Tank Mates:

  • Aggressive Fish: Cichlids, Oscars, puffers, loaches, goldfish, bettas, and some barbs may attack or eat your snails.
  • Predatory Invertebrates: Crayfish, giant assassin snails, and some pufferfish species will readily snack on Mystery snails.
  • Fish with Large Appetites: Plecos and some catfish may accidentally injure or eat snails while scavenging for food.

General Tips for Choosing Tank Mates:

  • Water Compatibility: Ensure all chosen species thrive in similar water parameters (pH, temperature, hardness).
  • Tank Size: Larger tanks offer more space and resources, reducing competition between species.
  • Individuality: Observe fish species for signs of aggression, even among generally peaceful options.
  • Introduce Carefully: Quarantine new fish to avoid introducing diseases to your established tank.

Following these tips and choosing compatible tank mates, you can create a thriving aquarium community where your Snail Mystery can live happily and healthily.

Note: Mystery snails make fantastic tank mates for Betta fish, and their size is a significant reason why. Reaching up to two inches long, these shelled buddies are too big for most bettas even to consider munching on.

Breeding Mystery Snails Process

Breeding mystery snails can be a rewarding and fascinating experience for aquatic enthusiasts. These peaceful and low-maintenance creatures can reproduce quickly in a suitable environment.

To begin breeding, ensure you have a male and female mystery snail in your tank. You can distinguish between the two genders by examining their genital openings, which are located on the right side of their bodies.

Once you have identified a pair, create a conducive breeding environment by providing ample vegetation for the snails to lay their eggs. Mystery snails are known to be prolific egg layers, with each clutch containing up to 200 eggs.

The breeding process typically occurs above the waterline, as the aquatic snails lay their eggs on hard surfaces such as tank glass or decorations. It is essential to keep the water quality high and the temperature stable to ensure the successful hatching of the eggs.

With the proper care and conditions, you can witness the fascinating life cycle of mystery snails as they hatch and grow into adorable baby snails.
