Why choose Zebrafish?

The Zebrafish is one of the most recognised freshwater fish in the world. Its distinctive metallic blue horizontal stripes, constant activity and incredible hardiness have made it a staple of the aquarium hobby for generations.

These energetic fish spend the day cruising through the upper and middle levels of the aquarium, rarely staying still for long. Kept in a proper school, they display fascinating social behaviour while adding constant movement and life to the aquarium.

Because of their adaptability and forgiving nature, Zebrafish are often recommended as one of the best fish for beginners, yet they remain just as enjoyable for experienced aquarists.

NTA Insight:
Many people overlook Zebrafish because they're so common, but they're popular for good reason. A healthy school of 10–15 Zebra Danios racing around a well-planted aquarium is incredibly entertaining to watch. They're active, resilient and forgiving, making them one of the best fish for learning the hobby while still being enjoyable enough to keep for years.

FAQ

How many Zebrafish should I keep?

Zebrafish should be kept in schools of at least eight fish. Larger groups display more natural schooling behaviour, reduce stress and create a much more impressive display.

Are Zebrafish peaceful?

Yes. They are peaceful community fish, although their energetic nature can overwhelm very timid or slow-moving species. They are best kept with other active fish.

Can they live with shrimp?

Adult shrimp are generally safe, but newly hatched shrimplets may be eaten. Dense mosses and heavily planted areas provide good protection for young shrimp.

Can Zebrafish breed in home aquariums?

Yes. They are one of the easiest egg-scattering fish to breed. Adults readily spawn in dedicated breeding tanks, but should be removed afterwards as they will eat their eggs.

Why are Zebrafish so popular?

Their hardiness, peaceful temperament, constant activity and iconic striped appearance make them one of the most reliable and enjoyable freshwater fish for aquarists of all experience levels.

    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.
