Duckweed (Lemna disperma) Starter Pack

A fast-growing Australian floating plant starter pack that provides surface cover, nutrient uptake and grazing habitat for shrimp, fry and small fish.

Quick Facts

  • Scientific name: Lemna disperma
  • Common name: Duckweed
  • Plant type: Floating plant
  • Selling form: Starter pack
  • Placement: Water surface
  • Difficulty: Very easy
  • Lighting: Low to high
  • CO₂: Not required
  • Growth rate: Very fast

Is this for you?

✔️ Perfect if:

  • You want quick floating cover.
  • You keep shrimp, fry or surface-shy fish.
  • You want a plant that rapidly uses dissolved nutrients.

❌ Avoid if:

  • You dislike frequent thinning of floating plants.
  • You need the entire surface open for strong light penetration.

Why choose Duckweed?

Duckweed multiplies rapidly and can quickly provide natural surface shade and habitat while helping absorb dissolved nutrients from the water column.

Benefits

  • Excellent cover for fry and shrimp.
  • Rapid nutrient uptake.
  • Very easy to propagate.
  • Useful for creating a more natural surface environment.

Care made simple

  • Float directly on the aquarium surface.
  • Thin regularly so it does not completely block light and gas exchange.
  • Keep away from heavy surface agitation that constantly submerges the fronds.
  • Remove excess during water changes.
  • Use a feeding ring if you want an open area for food and surface access.

Pairs perfectly with

  • Shrimp tanks
  • Fry-rearing aquariums
  • Betta and gourami tanks with calm surface zones
  • Low-tech planted aquariums
NTA Insight:
Duckweed is easy to grow and harder to control. The best approach is to decide early how much surface coverage you want and remove excess consistently.

FAQ

Does Duckweed need substrate?

No. It floats freely on the water surface.

Does it need CO₂?

No. Duckweed obtains carbon directly from the air and water surface environment.

Will it spread quickly?

Yes. Under suitable conditions it can multiply very rapidly, so regular thinning is expected.

What will I receive?

A starter pack of live Duckweed. Exact frond count and coverage naturally vary.

    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.
