C125 Ceará Bulldog Cory (Aspidoras raimundi) 3-5cm

Description

C125 Ceará Bulldog Cory (Aspidoras raimundi)

Compact, active and considerably less common than standard Corydoras, the C125 Ceará Bulldog Cory is a charming Brazilian Aspidoras with a finely spotted body, short robust profile and energetic social behaviour. Closely related to Corydoras but belonging to its own genus, Aspidoras raimundi is an excellent choice for collectors and aquarists wanting a smaller, unusual armoured catfish for a peaceful planted aquarium.

What is an Aspidoras?

At first glance, Aspidoras look very much like small Corydoras—and the two groups are close relatives within the Corydoradinae.

However, Aspidoras raimundi belongs to the separate genus Aspidoras, not Corydoras.

The familiar “Cory” name remains useful in the aquarium hobby, but scientifically this fish should be listed as Aspidoras raimundi.

C125 was originally used as a hobby identification number while the fish's identity was uncertain. Subsequent taxonomic work has associated C125 with Aspidoras raimundi.

Is this for you?

✔️ Perfect if:

  • You collect unusual Corydoras-type catfish.
  • You want a genuinely small bottom-dwelling species.
  • You have a planted aquarium with fine sand.
  • You enjoy social fish kept in proper groups.
  • You want something far less common than Bronze or Panda Corys.

❌ Avoid if:

  • You intend to keep only one or two.
  • Your aquarium has sharp or abrasive substrate.
  • You expect them to survive solely on leftover food.
  • You are purchasing them as algae eaters.
  • You keep large predatory bottom-dwelling fish.

Why choose C125 Ceará Bulldog Cory?

C125 offers all the social appeal people love about Corydoras in a smaller and much less commonly encountered package.

The fish has a compact body covered in variable dark spotting and mottling over a lighter base colour. Individual pattern intensity can differ naturally, giving a group a beautifully varied appearance.

They are active little catfish and spend much of their time exploring the substrate together, searching for food and resting amongst plants and shaded areas.

Their small adult size also makes them particularly attractive for aquarists who want a genuine social bottom-dweller without needing a large aquarium.

Benefits

  • Uncommon C-number catfish
  • Compact 4–5 cm adult size
  • Beautiful natural spotted pattern
  • Extremely peaceful temperament
  • Excellent social behaviour
  • Ideal for planted aquariums
  • Excellent addition to Corydoradinae collections
  • Can be bred successfully in captivity

Care made simple

  • Temperature: Approximately 20–25°C
  • pH: Approximately 6.0–7.5
  • Water: Clean, stable and well oxygenated
  • Diet: Quality sinking catfish foods supplemented with frozen and live foods
  • Excellent foods: Bloodworms, brine shrimp, daphnia and other appropriately sized foods
  • Substrate: Fine sand strongly preferred
  • Setup: Plants, driftwood, leaf litter and open sandy areas for foraging
  • Keep in a proper social group rather than individually.
  • Regular water changes and good oxygenation help maintain excellent condition.

Pairs perfectly with

  • Small Tetras
  • Rasboras
  • White Cloud Mountain Minnows where temperatures overlap
  • Peaceful dwarf cichlids
  • Otocinclus
  • Other compatible small Corydoradinae catfish
NTA Insight:
C125 is a good example of why the aquarium hobby's C-numbers are useful even after a fish receives a proper identification. Many aquarists still recognise this fish immediately as C125, while scientifically we now have Aspidoras raimundi. More importantly, don't treat them as bottom-cleaning equipment. Keep a proper group, use fine sand and deliberately feed them quality sinking foods and you'll see a very active little social catfish.

FAQ

What does C125 mean?

C125 is the aquarium hobby identification number historically used for this fish before its species identity was resolved. C125 has subsequently been associated with Aspidoras raimundi.

Is C125 actually a Corydoras?

No. Although it is closely related to Corydoras and commonly called a Cory in the aquarium trade, the correct genus is Aspidoras. The scientific name is Aspidoras raimundi.

Why is it called the Ceará Bulldog Cory?

The common name refers to its Brazilian association with Ceará and its compact, robust “bulldog” body shape compared with many more elongated Corydoras-type catfish.

How large does Aspidoras raimundi grow?

Adults generally reach approximately 4–5 cm, making this a genuinely small armoured catfish.

How many should I keep?

We recommend at least six, with eight or more preferred where aquarium space allows. They are social fish and show considerably more confident natural behaviour in groups.

Can I keep C125 with Corydoras?

Yes. They can coexist peacefully with appropriately sized Corydoradinae species, but other Corys should not be treated as a substitute for maintaining a proper group of Aspidoras raimundi.

Do they eat algae?

No. They are not algae-control fish. They require quality sinking foods and a varied omnivorous diet.

Can they survive on leftover fish food?

No. Make sure suitable sinking foods reach the substrate. Treating small armoured catfish as scavengers that survive on leftovers is a common husbandry mistake.

Why is fine sand recommended?

These fish naturally spend substantial time searching through substrate with their sensitive barbels. Fine sand encourages natural foraging behaviour and reduces the risk of abrasion.

Can C125 live with shrimp?

Adult shrimp can generally coexist successfully with them. Extremely small shrimplets may occasionally be eaten opportunistically, but these catfish are not active shrimp predators.

Can Aspidoras raimundi breed in aquariums?

Yes. The species can reproduce successfully in captivity. Well-conditioned groups maintained on a varied diet and clean, oxygen-rich water provide the best starting point for breeding.

How can I tell males and females apart?

Mature females generally become larger and noticeably fuller through the abdomen, especially when viewed from above, while males tend to remain smaller and slimmer.

Are they suitable for beginners?

Yes, provided the aquarium is mature and stable and the fish are maintained as a proper group with fine substrate and deliberate feeding.

    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.
