Why choose Corydoras CW34?

CW34 is an unusual Bolivian Corydoras-type catfish that remains scientifically undescribed, making its CW identification number particularly important for maintaining its identity within the aquarium hobby.

The Freckled Bolivian Cory develops an attractive natural pattern of dark spots and freckles across a lighter body, giving each fish a beautifully textured appearance without relying on selectively bred colouration.

Like other Corydoradinae catfish, they are strongly social. A proper group will spend its time exploring the substrate together, searching for food and resting amongst plants, timber and shaded areas.

Their peaceful temperament also makes them excellent community inhabitants when combined with appropriately sized Tetras, Rasboras, Rainbowfish, dwarf cichlids and other non-aggressive species.

Benefits

  • Distinctive natural freckled pattern
  • Bolivian South American origin
  • Peaceful community temperament
  • Excellent social behaviour in groups

  • Suitable for planted and natural South American aquariums

Care made simple

  • Temperature: Approximately 22–27°C
  • pH: Approximately 6.0–7.5
  • Diet: Quality sinking catfish pellets and wafers supplemented with frozen bloodworms, brine shrimp, daphnia and other appropriately sized foods
  • Water: Clean, stable and well oxygenated
  • Substrate: Fine sand is strongly preferred
  • Setup: Plants, driftwood, leaf litter and sheltered areas with plenty of open substrate for foraging
  • Keep in groups of at least six to encourage confident, natural social behaviour.
  • Regular water changes and a varied diet help maintain excellent condition.

Pairs perfectly with

  • Small to medium Tetras
  • Rasboras
  • Rainbowfish
  • Peaceful dwarf cichlids
  • Other compatible Corydoradinae catfish
NTA Insight:
CW34 is the sort of fish that makes collecting Corydoras-type catfish so interesting. It doesn't yet have a formally described species name, so the CW034 number isn't just a catalogue code—it is an important part of maintaining the identity of this particular fish. Give them fine sand, good oxygenation, quality sinking foods and, most importantly, a proper group. A single Cory sitting quietly in a corner doesn't show you what these wonderfully social fish are really like.

FAQ

What does CW34 mean?

CW34, also written CW034, is a Corydoras World identification number. CW numbers are used within the aquarium hobby to distinguish Corydoradinae forms that have not yet received a formal scientific species description.

Is CW34 still scientifically called Corydoras?

Traditionally this fish has been known as Corydoras sp. CW034. Following the newer revision of Corydoradinae classification, CW034 is placed within Brochis, making Brochis sp. CW034 the more current classification. Corydoras CW34 remains the much more familiar aquarium trade name.

Why is it called the Freckled Bolivian Cory?

The common name refers to its Bolivian origin and the attractive dark spotting or freckling distributed across its body.

How many CW34 should I keep?

We recommend at least six, with groups of eight or more preferred where aquarium space allows. These are highly social fish and generally become more confident and active when maintained in a proper group.

Can CW34 live with other Corydoras?

Yes. They can coexist peacefully with other compatible Corydoradinae catfish. However, other species should not be considered a complete replacement for keeping several CW34 together if you want to observe their best natural social behaviour.

Do CW34 eat algae?

No. They may investigate surfaces while searching for food, but they are not algae-control fish. They require deliberate feeding with nutritionally complete sinking foods.

Will they survive on leftover fish food?

No. Corys are sometimes incorrectly treated as aquarium scavengers that survive on whatever reaches the bottom. CW34 requires its own quality sinking foods supplemented with suitable frozen or live foods.

Why is sand recommended?

These fish naturally spend considerable time searching through the substrate with their sensitive barbels. Fine sand allows this behaviour while reducing the risk of abrasion associated with sharp or coarse substrates.

Can CW34 live with dwarf cichlids?

Yes, in appropriately sized aquariums they can make excellent companions for peaceful dwarf cichlids. During spawning, however, cichlids may defend territories from Corys that wander too close to eggs or fry.

Can CW34 breed in an aquarium?

Breeding may be possible when mature fish are maintained in suitable groups and excellent condition. Because CW034 remains relatively uncommon, maintaining correctly identified fish and avoiding unnecessary hybridisation with similar forms is particularly important for serious breeding projects.

Are CW34 suitable for beginners?

They can be suitable for aquarists comfortable maintaining stable water quality and correctly feeding bottom-dwelling fish. Their rarity, however, means we recommend giving them more consideration than an inexpensive common Cory.

    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.
