Corydoras CW127 (Hoplisoma sp. CW127)

Rare, striking and highly sought after, Corydoras CW127 is a beautiful Brazilian Corydoras-type catfish recognised by its bold dark markings, contrasting pale body and distinctive streamlined pattern. Sometimes encountered in the hobby as "Super Parallelus", this undescribed CW-number species combines collector-level rarity with the peaceful, social personality that makes Corys such rewarding aquarium fish.

Why choose Corydoras CW127?

CW127 is one of those Corys that immediately attracts attention. Its bold dark markings contrast beautifully against the lighter body, producing a clean and distinctive pattern that looks particularly impressive when a group moves together across a light sandy substrate.

This fish has occasionally been sold under the name "Super Parallelus" because of its resemblance to the highly sought-after Parallelus Cory. However, CW127 represents a distinct form originating from the Rio Tapajós system and should not be confused with the true Hoplisoma parallelum.

Like other members of the group, CW127 is strongly social. Keeping a proper group allows them to forage together, rest together and display the confident behaviour that makes Cory-type catfish so entertaining.

Benefits

  • Rare and desirable CW-number catfish
  • Beautiful contrasting body pattern
  • Compact adult size
  • Peaceful community temperament
  • Excellent social behaviour in groups
  • Fantastic addition to specialist Cory collections
  • Suitable for planted and South American-style aquariums

Care made simple

  • Temperature: Approximately 20–25°C
  • pH: Approximately 6.0–7.2
  • Diet: Quality sinking catfish pellets and tablets supplemented with frozen or live foods such as bloodworms, brine shrimp and daphnia
  • 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 and natural social behaviour.
  • Regular water changes and good oxygenation are strongly recommended.

Pairs perfectly with

  • Small to medium Tetras
  • Rasboras
  • Peaceful dwarf cichlids
  • Small peaceful plecos
  • Other compatible Corydoradinae catfish
NTA Insight:
CW127 is sometimes called "Super Parallelus", but we wouldn't sell it as simply a Parallelus Cory. It is a distinct CW-number fish from the Rio Tapajós drainage and remains scientifically undescribed. For collectors, that distinction matters. Keep them as a proper group over fine sand, provide excellent oxygenation and feed them deliberately rather than expecting them to live on leftovers. This is a feature Cory, not a clean-up crew fish.

FAQ

What does CW127 mean?

CW127 is a Corydoras World identification number used to distinguish this particular Corydoradinae catfish while it remains without a formally described scientific species name.

Is CW127 still a Corydoras?

It has traditionally been sold as Corydoras sp. CW127. Under the newer classification of Corydoradinae catfish, it is placed within Hoplisoma, making Hoplisoma sp. CW127 the more current identification. Corydoras CW127 remains the familiar aquarium trade name.

Is CW127 the same as Corydoras parallelus?

No. CW127 resembles the fish traditionally known as Corydoras parallelus and has consequently appeared under the trade name "Super Parallelus". However, they are distinct fishes with different known geographic origins and should not be treated as the same species.

Where does CW127 come from?

CW127 originates from Brazil and is associated with a tributary of the Rio Jamanxim within the Rio Tapajós drainage.

How large does CW127 grow?

Adults remain relatively compact at around 5.5–6 cm, with mature females generally becoming somewhat larger and fuller-bodied than males.

How many CW127 should I keep?

We recommend at least six, with eight or more preferred where aquarium space and budget allow. These are highly social fish and become considerably more confident when maintained as a proper group.

Can CW127 live with other Corydoras?

Yes. They can coexist peacefully with compatible Corydoradinae species. However, keeping other Cory species does not remove the benefit of maintaining several CW127 together.

Do CW127 eat algae?

No. They are not algae-control fish. CW127 requires deliberate feeding with nutritionally complete sinking foods supplemented with appropriate frozen or live foods.

Can they survive on leftover fish food?

No. Corys should never be treated simply as scavengers. Make sure quality sinking foods reach the substrate so the CW127 receive a complete diet rather than relying on whatever other fish fail to eat.

Why is fine sand recommended?

CW127 spends considerable time searching through the substrate for food. Fine sand allows this natural behaviour and is gentle on the sensitive barbels around the mouth.

Can CW127 breed in an aquarium?

Yes. CW127 has been bred successfully in captivity. Mature, well-conditioned groups can spawn under appropriate conditions, and cooler water changes combined with excellent oxygenation may help stimulate breeding behaviour.

Are CW127 suitable for beginners?

They are not exceptionally difficult fish, but their rarity and value mean we recommend them for aquarists who already understand stable water quality, proper Cory feeding and the importance of keeping social catfish in groups.

    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.
