  • 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 prefer a natural-looking aquarium
  • You keep a peaceful community tank
  • 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 or acidic water
  • You expect snails to replace aquarium maintenance
  • You don't want occasional egg clutches above the waterline

Why this snail?

The Brown Mystery Snail is one of the original and most popular colour varieties of Pomacea diffusa. Its rich chocolate-brown shell gives it a natural appearance that blends beautifully into planted aquariums and nature-style aquascapes.

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

Unlike common 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

  • Expecting them to survive on algae alone
  • Keeping them with snail-eating fish
  • Allowing low pH to damage the shell
  • 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:
Brown Mystery Snails are a favourite for natural aquascapes because their earthy shell colour blends beautifully with driftwood, rocks, and planted layouts. While they may not be as flashy as some colour morphs, they're timeless, hardy, and full of personality.

FAQ

Will Brown Mystery Snails overpopulate my aquarium?

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

Do they eat healthy aquarium plants?

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

Are they good algae eaters?

They help graze algae and biofilm from aquarium surfaces but should not be relied upon as the sole method of algae control.

Can they live with shrimp?

Yes. Brown 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 stable water with a pH above 7.0 and provide a calcium source such as cuttlebone or calcium-rich foods to support strong, 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.
