Why choose Fantail Goldfish?

Fantail Goldfish are one of the original fancy goldfish varieties and remain among the most popular today. Their rounded body, flowing double tail and elegant swimming style create a peaceful, eye-catching display that suits both modern aquariums and traditional goldfish setups.

Available in colours including orange, red, white, black, calico and bi-colour combinations, every Fantail has its own unique appearance. They quickly become tame, often swimming to the front of the aquarium to greet their owners at feeding time.

Compared with single-tail goldfish such as Comets, Fantails swim more slowly and are best housed with other fancy goldfish that share similar swimming abilities.

NTA Insight:
Fantails are often underestimated because they're commonly sold as small juveniles. Given the right care, they grow into beautiful, personable fish that can live for well over a decade. We recommend feeding sinking foods rather than floating flakes to help reduce the amount of air they swallow, which can contribute to buoyancy issues in some fancy goldfish.

FAQ

How big do Fantail Goldfish grow?

Most adult Fantails reach 15–20 cm, although exceptional specimens may grow slightly larger in spacious aquariums with excellent care.

Can Fantail Goldfish live in a bowl?

No. Bowls do not provide adequate swimming space, filtration or stable water quality. Fantails require a properly filtered aquarium with plenty of room to grow.

Can I keep Fantails with Comet Goldfish?

It's generally not recommended. Comets are much faster swimmers and can outcompete Fantails for food. Fancy goldfish are happiest when kept with other fancy varieties.

Do Fantail Goldfish need a heater?

Usually no. They are coldwater fish and are comfortable within normal indoor temperatures in most Australian homes. Consistent temperatures are more important than warm temperatures.

How long do Fantail Goldfish live?

With proper care, high-quality filtration and a balanced diet, Fantail Goldfish commonly live 10–15 years, with many living considerably longer.

    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.
