  • Common name: Corydoras CW106
  • Origin: Wild caught – Colombia

What makes CW106 special?

CW106 is one of the more recently recognised C-number Corydoras and remains exceptionally uncommon in Australia. The first known imports only arrived in Australia during 2021, making it a genuine collector's species for Corydoras enthusiasts. :contentReference[oaicite:0]{index=0}

This beautiful long-snouted species originates from the Cuduyarí River system in Colombia and is closely associated with the similarly patterned CW107 and CW89. Its distinctive dark band extending from the dorsal fin into the lower caudal lobe is one of its defining characteristics. :contentReference[oaicite:1]{index=1}

Despite its rarity, its care is very similar to most Corydoras species. Given clean, oxygen-rich water, soft sand and quality nutrition, CW106 becomes an active and rewarding fish that constantly explores the aquarium alongside its companions.

NTA Insight:
Wild-caught Corydoras like CW106 deserve a little extra patience during acclimation. They often arrive shy after import but settle beautifully into mature aquariums with stable water quality and plenty of cover. We always recommend purchasing them in groups rather than individually—not only because they're naturally social, but because schooling helps them settle faster and display far more natural behaviour.

FAQ

Why is this fish called CW106?

CW numbers are hobby identification codes given to undescribed or newly imported Corydoras species before they receive formal scientific classification. CW106 remains widely recognised by this code among collectors. :contentReference[oaicite:2]{index=2}

How many CW106 should I keep?

Keep them in groups of at least six. Larger groups of 8–10 or more encourage natural schooling behaviour, improve confidence and reduce stress.

Do they eat algae?

No. Like all Corydoras, they are not algae eaters. They require a varied diet of quality sinking foods, supplemented with frozen and live foods for optimum health.

Can they live with shrimp?

Yes. Adult Neocaridina and Caridina shrimp generally coexist well with CW106. Dense mosses and plants provide excellent refuge for young shrimplets.

Why is fine sand recommended?

CW106 naturally sift through soft substrates using their sensitive barbels. Fine sand allows this natural feeding behaviour while helping prevent barbel wear and injury that can occur on coarse gravel. :contentReference[oaicite:3]{index=3}

    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.
