Why choose Corydoras blochi?

Corydoras blochi is an attractive and underrated Corydoras species native to northern South America. Its body displays beautiful metallic bronze and olive tones with delicate dark speckling, creating a natural appearance that blends perfectly into planted aquariums.

Like all Corydoras, Blochi are highly social catfish that spend their day searching the substrate for food using their sensitive barbels. They're constantly active, often moving together as a group before resting beneath driftwood or broad-leaved plants.

Their peaceful temperament, hardy nature and fascinating behaviour make them an excellent choice for both beginner and experienced aquarists.

Benefits

  • Beautiful metallic bronze colouration
  • Excellent community fish
  • Peaceful with other aquarium inhabitants
  • Active daytime bottom forager
  • Suitable for planted aquariums
  • Hardy and beginner friendly

Care made simple

  • Temperature: 22–27Β°C
  • pH: 6.0–7.5
  • Diet: Premium sinking pellets, Corydoras wafers, frozen bloodworms, brine shrimp and live foods
  • Water: Clean, mature and well-filtered
  • Setup: Fine sand substrate, driftwood, plants and shaded resting areas
  • Soft sand is strongly recommended to protect their delicate barbels.

Pairs perfectly with

  • Harlequin Rasboras
  • Cherry Barbs
  • Rainbowfish
  • Apistogramma
  • Cherry and Crystal Shrimp
NTA Insight:
Blochi may not receive as much attention as Panda or Sterbai Corydoras, but they're every bit as rewarding to keep. Their subtle metallic colours become increasingly attractive as they mature, and like all Corydoras, their personality shines once they're kept in a proper group. A school of 8–10 fish constantly exploring a sandy planted aquarium is one of the most enjoyable sights in freshwater fishkeeping.

FAQ

How many Corydoras blochi should I keep?

They are social fish and should be kept in groups of at least six. Groups of 8–10 or more encourage natural schooling behaviour and help the fish become more confident.

Are Corydoras blochi good cleaners?

They help consume uneaten food from the substrate, but they still require their own balanced diet of quality sinking foods and should never be relied upon as "clean-up fish."

Can they live with shrimp?

Yes. Adult Neocaridina and Caridina shrimp are generally safe alongside Corydoras blochi. Tiny shrimplets may occasionally be eaten, but established shrimp colonies usually coexist well in planted aquariums.

Why do Corydoras swim to the surface?

This is completely normal. Corydoras periodically gulp atmospheric air, which supplements their oxygen intake. Occasional trips to the surface are a natural behaviour and not usually a sign of poor health.

Why is fine sand recommended?

Corydoras naturally sift through soft substrates using their sensitive barbels to locate food. Fine sand allows this instinctive behaviour while helping prevent wear and injury that can occur on coarse gravel.

    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.
