Quick Facts

  • Size: ~4–6 cm
  • Tank size: 20L+ recommended
  • Difficulty: 🟢 Easy
  • Temperament: Peaceful
  • Best kept: Singly or in groups

Is this for you?

āœ”ļø Good if:

  • You want one of the rarer Mystery Snail colour varieties
  • You keep a peaceful community aquarium
  • You enjoy active and entertaining invertebrates
  • You want a natural algae and biofilm grazer

āŒ Avoid if:

  • You keep snail-eating fish such as puffers or loaches
  • You have consistently soft, acidic water
  • You expect snails to replace aquarium maintenance
  • You don't want occasional egg clutches above the waterline

Why this snail?

The Purple Mystery Snail is one of the most sought-after colour varieties of Pomacea diffusa. Its beautiful lavender to deep purple shell provides a unique contrast against green plants, driftwood, and darker substrates.

Mystery Snails are peaceful scavengers that spend their day grazing on algae, biofilm, and leftover food while exploring every corner of the aquarium with surprising curiosity.

Unlike common pest snails, Mystery Snails reproduce slowly. They require both a male and female, with egg clutches laid above the waterline where they can easily be removed if breeding is not desired.

Common mistakes

  • Assuming they survive on algae alone
  • Keeping them with snail-eating fish
  • Allowing pH to remain too low, causing shell erosion
  • Not providing enough calcium for healthy shell growth
  • Overfeeding and reducing water quality

Care made simple

  • Temperature: 20–28°C
  • pH: 7.0–8.2
  • Diet: Algae, biofilm, algae wafers, blanched vegetables
  • Water: Moderate to hard water preferred
  • Setup: Mature aquarium with a secure lid

Pair with

  • Peaceful community fish
  • Freshwater shrimp
  • Live plants
  • Algae wafers
  • Calcium supplements or cuttlebone
NTA Insight:
Purple Mystery Snails are among the rarer colour morphs available and often become the centrepiece of smaller aquariums. Their unusual shell colour, combined with their curious personality, makes them a favourite for aquascapers looking for something a little different.

FAQ

Will Purple Mystery Snails overpopulate my aquarium?

No. They require both a male and female to breed, and their egg clutches are laid above the waterline where they can easily be removed.

Do they eat healthy aquarium plants?

No. Purple Mystery Snails primarily feed on algae, biofilm, leftover food, and decaying plant matter rather than healthy live plants.

Are they good algae eaters?

Yes. They help graze algae and biofilm from glass, decorations, and hardscape, but they should not replace regular aquarium maintenance.

Can they live with shrimp?

Absolutely. Purple Mystery Snails are peaceful and make excellent companions for freshwater shrimp and other non-aggressive aquarium species.

How do I keep the shell healthy?

Maintain a pH above 7.0, provide moderate to hard water, and ensure a good calcium source such as cuttlebone or calcium-rich foods to support healthy shell growth.

    Live Arrival & Ordering FAQ

    Why do livestock prices sometimes change?

    Unlike manufactured products, fish and shrimp continue to grow and develop over time. Their value changes as they increase in size, develop colour, or become breeding pairs.

    Our prices are based on the current size, quality and availability of each specimen. While pricing often remains stable for around 3–4 months, it may be updated at any time to reflect these changes.

    We always aim to offer healthy, high-quality livestock at fair and competitive prices.

    Do you offer a live arrival guarantee?

    Yes. All livestock is covered by our Live Arrival Guarantee.

    In the rare event of DOA, please contact us promptly with clear photos of the livestock in the original unopened bag.

    Please review our full DOA and store policies before purchase.

    Can you ship to all states in Australia?

    No. Due to state restrictions, we cannot ship livestock or live plants to WA and TAS.

    What should I check before ordering?

    Before placing an order, make sure:

    • Your tank is fully cycled and stable
    • Your aquarium has enough space for the species
    • Your current livestock are compatible in temperament, size, and requirements
    • Your water parameters, habitat, and temperature suit the species
    • You are not adding too many fish at once
    What should I expect when my fish arrives?

    It is normal for fish, shrimp, or snails to look pale, stressed, or less active after shipping.

    This is temporary. Most livestock will settle and regain colour within a few days.

    How long does it take for fish to settle in?

    Most livestock will take 3–7 days to fully adjust to their new environment.

    Should I feed my fish immediately after arrival?

    No. We recommend waiting 24 hours before feeding to allow them to settle.

    If you already have fish in your tank, feeding them before introducing new arrivals can help reduce stress.

    Why do fish sometimes struggle after being added to a tank?

    In most cases, issues are caused by tank conditions, not shipping.

    • Uncycled or unstable tanks
    • Poor water parameters
    • Overstocking
    • Unsuitable tank mates
    What is Nano Tanks Australia’s main tip for new livestock?

    Most livestock losses happen in immature or unstable tanks, not during shipping.

    If your setup is not fully established, the risk to new arrivals is significantly higher.

    Not sure if this fish is right for your setup?

    If you are unsure whether this species suits your setup, contact us before ordering and we’ll help point you in the right direction.
