Why choose Weitzman's Cory?

Corydoras weitzmani is regarded as one of the most beautiful Corydoras available. Its pearly silver body is highlighted by a bold black mask running through the eyes, creating an elegant contrast that immediately catches the eye. Under quality lighting, mature fish often display subtle blue and green iridescence across their body.

Native to the upper Amazon basin of Peru, this species prefers cool, clean and well-oxygenated water. Like all Corydoras, they spend much of their day foraging across the substrate, gently sifting through the sand with their sensitive barbels while remaining completely peaceful with other aquarium inhabitants.

Although considered a collector's species due to its limited availability, their care is very similar to many other Corydoras provided excellent water quality is maintained.

Benefits

  • Rare collector's Corydoras
  • Distinctive black eye mask
  • Beautiful metallic silver body
  • Peaceful community fish
  • Excellent for planted aquariums
  • Active daytime bottom dweller

Care made simple

  • Temperature: 21–25Β°C
  • pH: 6.0–7.2
  • Diet: Premium sinking pellets, Corydoras wafers, frozen bloodworms, blackworms, brine shrimp and quality live foods
  • Water: Clean, mature, highly oxygenated and well-filtered
  • Setup: Fine sand substrate, driftwood, leaf litter, plants and shaded resting areas
  • Maintain stable water quality and avoid sharp gravel to protect their barbels.

Pairs perfectly with

  • Celestial Pearl Danios
  • Harlequin Rasboras
  • Apistogramma
  • Peaceful Rainbowfish
  • Cherry and Crystal Shrimp
NTA Insight:
Weitzman's Cory is often described as one of the "gentlemen" of the Corydoras world. Their crisp black eye mask and shimmering silver body give them an understated elegance that photographs rarely capture properly. Like all Corydoras, they truly come alive when kept in groups of 6–10 or more, confidently exploring every corner of the aquarium together.

FAQ

How many Weitzman's Corys should I keep?

Keep them in groups of at least six. Larger groups of 8–10 or more display more natural schooling behaviour and are noticeably more confident.

Are Corydoras weitzmani suitable for community aquariums?

Yes. They are exceptionally peaceful and mix well with rasboras, tetras, rainbowfish, dwarf cichlids and other non-aggressive species.

Can they live with shrimp?

Absolutely. Adult Neocaridina and Caridina shrimp are generally ignored, making Weitzman's Cory an excellent companion for shrimp aquariums.

Why is sand recommended?

Like all Corydoras, they naturally sift through the substrate using their sensitive barbels. Fine sand allows this behaviour while helping prevent barbel damage caused by coarse gravel.

Are Corydoras weitzmani difficult to keep?

Not particularly, but they appreciate stable water conditions, excellent oxygenation and a mature aquarium. Their rarity makes them more valuable, so maintaining high water quality is especially worthwhile.

    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.
