Why choose Blue Cobra Guppies?

The Blue Cobra Guppy combines one of the most popular guppy colours with one of the hobby's most recognisable patterns. Its body is decorated with fine, snakeskin-like markings that may form chains, rosettes or irregular reticulated patterns, while the fins display varying shades of blue, turquoise and metallic highlights.

Mature males develop the strongest colour and most elaborate finnage, creating a brilliant flash of blue as they move through the aquarium. Females are generally larger and more subtly coloured, making them valuable for maintaining and selectively breeding the strain.

Their peaceful temperament, manageable care requirements and constant activity make them equally suitable for newer aquarists and experienced guppy collectors.

NTA Insight:
The term “Cobra” refers to the intricate snakeskin-style pattern that runs across the body and may continue into the fins. In Blue Cobra Guppies, these markings contrast beautifully against the cool blue base colour. A dark substrate, lush green plants and full-spectrum LED lighting will make the metallic blue tones appear even more intense.

    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.
