NTA Insight:
Rosy Barbs are one of the best all-round community fish available. They're colourful, incredibly hardy and full of personality. Many people only notice the males, but a mixed group creates the best display, especially during breeding season when the males intensify into brilliant shades of crimson. If you're looking for a larger schooling fish that's both forgiving and rewarding, Rosy Barbs are hard to beat.

FAQ

How many Rosy Barbs should I keep?

Rosy Barbs are schooling fish and should be kept in groups of at least six. Schools of 8–10 or more encourage natural behaviour, improve confidence and create a far more impressive display.

Are Rosy Barbs peaceful?

Yes. They are generally peaceful community fish and mix well with other active species of a similar size. Keeping them in a proper school helps minimise any chasing behaviour.

Can they live with shrimp?

Due to their adult size, Rosy Barbs may eat dwarf shrimp and shrimplets. They are best suited to fish-only community aquariums or tanks with larger shrimp species.

Can Rosy Barbs breed in home aquariums?

Yes. They are prolific egg scatterers and will breed readily in clean aquariums with fine-leaved plants or spawning mops. Adults should be removed after spawning, as they will eat their eggs.

Why are my Rosy Barbs not bright red?

Only mature males develop the intense rosy-red breeding colouration. Good nutrition, clean water, plenty of swimming space and the presence of females will help males display their brightest colours.

    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.
