Why choose Corydoras CW51?

Known in the hobby as the New Panda Cory, CW51 is one of the most attractive undescribed Corydoras to enter the aquarium trade. It features a distinctive black saddle behind the dorsal fin, bold facial markings and an elegant silver body, giving it a striking appearance reminiscent of the famous Panda Cory while remaining a completely different species. :contentReference[oaicite:0]{index=0}

Wild collected from Colombia, CW51 is highly prized by Corydoras enthusiasts for its rarity, attractive pattern and relatively hardy nature. Like all Corydoras, they spend their day actively searching the substrate for food before resting together beneath driftwood or broad-leaved plants. :contentReference[oaicite:1]{index=1}

A group of these beautiful catfish becomes increasingly confident over time, regularly exploring the aquarium together and displaying the charming social behaviour Corydoras are famous for.

NTA Insight:
CW51 is one of those Corydoras that tends to attract collectors the moment they see it. The bold black saddle marking gives it a "mini Panda Cory" appearance, but it's a distinct species in its own right. Like all Corydoras, the real magic happens when they're kept in a proper group. Six is the minimum, but a school of 8–12 will spend much more time out in the open and display fascinating social behaviour.

FAQ

What does "CW51" mean?

CW numbers are identification numbers assigned to undescribed or recently imported Corydoras species in the aquarium hobby. CW51 is commonly known as the "New Panda Cory" because of its distinctive markings. :contentReference[oaicite:2]{index=2}

How many Corydoras CW51 should I keep?

Keep them in groups of at least six. Larger groups of 8–10 or more encourage natural schooling behaviour and help the fish become more confident.

Can they live with shrimp?

Yes. Adult Neocaridina and Caridina shrimp are generally safe alongside CW51. Newly hatched shrimplets may occasionally be eaten, but established shrimp colonies usually coexist well in heavily planted aquariums.

Do they need sand?

Yes. Fine sand is strongly recommended as it allows them to forage naturally and helps protect their sensitive barbels from damage.

Are CW51 difficult to keep?

Not particularly. Although they are considered a collector's species due to their rarity, their care requirements are very similar to most Corydoras—clean water, soft substrate, a varied sinking diet and the company of their own kind.

    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.
