These active schooling fish are constantly on the move, gliding effortlessly through the aquarium with their extended fins flowing behind them. Their peaceful nature and hardy temperament make them an excellent choice for larger community aquariums.

A well-planted aquarium with plenty of open swimming space allows these stunning fish to truly show off both their colour and graceful finnage.

NTA Insight:
Long Fin Rosy Barbs are one of those fish that become more impressive as they mature. Healthy adult males develop deep rosy-red colours while their flowing fins create an elegant display that's rarely seen in active schooling fish. Keep them in a group of 8–10 or more and they'll quickly become one of the highlights of your aquarium.

FAQ

How many Long Fin Rosy Barbs should I keep?

They should be kept in schools of at least six fish, although groups of 8–10 or more provide the best colours, confidence and natural schooling behaviour.

Are Long Fin Rosy Barbs peaceful?

Yes. They are peaceful community fish and mix well with other active, similarly sized species. Avoid keeping them with aggressive or persistent fin-nippers.

Can they live with shrimp?

Because of their larger adult size, they may eat dwarf shrimp and shrimplets. They are best suited to fish-only community aquariums.

Can Long Fin Rosy Barbs breed in home aquariums?

Yes. They are egg scatterers and will readily breed in dedicated breeding aquariums with fine-leaved plants or spawning mops. Adults should be removed after spawning to protect the eggs.

What makes the Long Fin variety different?

The Long Fin Rosy Barb has been selectively bred for beautifully elongated fins, giving it a much more graceful appearance while retaining the hardy nature, peaceful temperament and vibrant colours of the standard Rosy Barb.

    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.
