Why choose the Bearded Corydoras?

Originally found in the cool, clear coastal rivers of south-eastern Brazil, the Bearded Corydoras is one of the largest and most distinctive members of the Corydoras group. Unlike typical Corydoras, mature males develop elongated fins and pronounced fleshy bristles around the snout, giving the species its common name.

Their elegant swimming style, constant foraging and peaceful temperament make them an excellent addition to larger planted aquariums. Kept in groups, they confidently explore the substrate together, displaying fascinating natural social behaviour throughout the day.

Although hardy once established, they appreciate excellent water quality, high oxygen levels and cooler temperatures than many tropical catfish, closely reflecting their natural habitat.

FAQ

Why is it sometimes called Corydoras barbatus?

The species was originally classified within the Corydoras genus but has since been reclassified as Scleromystax barbatus. Both names are still commonly seen in the aquarium hobby.

How many should I keep?

Bearded Corydoras are social fish and should be kept in groups of at least five or six. Larger groups encourage more natural and confident behaviour.

Why is fine sand important?

They constantly sift through the substrate using their sensitive barbels. Fine sand helps prevent injury and allows natural foraging behaviour.

Do they eat algae?

No. They are not algae eaters and require a varied diet of quality sinking foods and protein-rich frozen or live foods.

Can they live with shrimp?

Adult shrimp are generally safe, although very small shrimplets may occasionally be eaten while the catfish forage through the substrate.

Are they suitable for beginners?

They are better suited to intermediate and experienced aquarists due to their preference for cooler, highly oxygenated water and consistently excellent water quality.

How long do Bearded Corydoras live?

With excellent care, they commonly live between 8 and 12 years, making them a rewarding long-term addition to a well-maintained aquarium.

    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.
