Why choose our Australian Live Blackworms?

Our Live Blackworms are harvested fresh from cool, clean waterways in Victoria before being carefully packed to maximise freshness. Rich in natural protein and healthy fats, they stimulate feeding responses that frozen and dry foods simply cannot match.

They are widely regarded as one of the best conditioning foods for breeding fish, helping improve spawning condition, colour development and growth in juvenile fish. Even notoriously fussy species often cannot resist live blackworms.

Every shipment is handled with care and packed with minimal water and ice packs to reduce ammonia build-up during transport and maximise survival during overnight shipping.

  • Excellent conditioning food for breeding fish
  • Ideal for fry and juvenile fish growth

NTA Insight:
Live Blackworms are one of our favourite foods for conditioning breeding fish and encouraging difficult species to feed. While they can be cultured at home, maintaining a healthy colony requires cool water, excellent filtration and regular maintenance. For most hobbyists, purchasing fresh worms as needed is the easiest and most reliable option.

FAQ

What are Live Blackworms?

Live Blackworms (Lumbriculus variegatus) are freshwater segmented worms naturally found in cool marshes, ponds and slow-moving waterways. They are one of the highest-quality live foods available for aquarium fish.

Where do your worms come from?

Our worms are harvested fresh in Victoria from clean, cool waterways before being shipped to Nano Tanks Australia.

Why do you ship them with very little water?

Water quickly accumulates ammonia during transport. Packing with minimal water and ice helps maximise survival during overnight shipping.

Can I breed Live Blackworms?

Yes. Blackworms reproduce both by fragmentation and by laying eggs. However, maintaining a productive colony requires cool water, good filtration and regular care, making it impractical for many hobbyists.

How should I keep them alive?

Store them in cool, clean, well-oxygenated water with gentle flow. Frequent rinsing and low temperatures greatly extend their lifespan.

Can they be shipped Australia-wide?

No. Live Blackworms are only shipped to locations serviced by reliable overnight delivery. We do not ship to rural or remote areas, and shipping is suspended during the hottest months (November to February).

Is there a DOA guarantee?

No. Due to the delicate nature of Live Blackworms and their sensitivity to temperature and shipping delays, no Dead On Arrival guarantee is provided.

    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.
