  • Size: ~4–6 cm
  • Tank size: 20L+ recommended

  • Best kept: Singly or in groups

Is this for you?

āœ”ļø Good if:

  • You want a unique and colourful freshwater snail
  • You keep a peaceful community aquarium
  • You enjoy watching active invertebrates
  • You want a natural algae and biofilm grazer

āŒ Avoid if:

  • You keep snail-eating fish such as puffers or loaches

  • You don't want occasional egg clutches above the waterline

Why this snail?

The Blue Mystery Snail is one of the most eye-catching colour varieties of Pomacea diffusa, featuring a beautiful blue-grey shell that contrasts brilliantly against green plants and dark aquascapes.

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

Unlike pest snails, Mystery Snails reproduce much more 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:
Blue Mystery Snails are one of the rarer colour varieties available. Their blue-grey shells create a striking contrast in planted aquariums, and their curious behaviour quickly makes them one of the most entertaining inhabitants in the tank.

FAQ

Will Blue 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. Healthy Blue Mystery Snails generally feed on algae, biofilm, leftover food, and decaying plant matter rather than healthy live plants.

Are they good algae eaters?

They help control algae and biofilm on aquarium surfaces, but they should not be relied upon as the sole solution for algae management.

Can they live with shrimp?

Yes. Blue Mystery Snails are completely peaceful and make excellent companions for freshwater shrimp and other non-aggressive aquarium species.

Why is my snail's shell fading or becoming rough?

Shell erosion is usually caused by soft or acidic water and insufficient calcium. Maintaining stable water conditions and providing a calcium source will help keep the shell healthy.

    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.
