Quick Facts

  • Size: Approx. 3–4 cm juvenile
  • Adult Size: Approx. 5–6 cm
  • Tank Size: 40L+ recommended
  • Difficulty: 🟢 Easy
  • Temperament: Peaceful
  • Best Kept: Groups of 4–6+

Is this for you?

✔️ Good if:

  • You want peaceful bottom-level activity
  • You keep planted or community aquariums
  • You can provide soft substrate
  • You are happy to keep a proper group

❌ Avoid if:

  • You want a solitary fish
  • You use sharp gravel
  • You expect them to survive on leftovers only
  • You keep aggressive bottom dwellers

Why this fish?

Corydoras oiapoquensis is a peaceful South American catfish that adds constant movement and natural behaviour to the lower areas of the aquarium.

They actively forage through the substrate searching for food, creating a more natural and engaging tank environment.

This species works especially well in planted community aquariums where gentle behaviour and schooling activity are preferred.

Common mistakes

  • Keeping them alone → increased stress
  • Using sharp gravel that damages barbels
  • Assuming they survive only on leftovers
  • Overcrowding the bottom zone
  • Ignoring stable water quality

Care made simple

  • Temperature: 22–26°C
  • Diet: Sinking pellets, wafers, frozen foods
  • Group Size: 4–6+ recommended
  • Substrate: Soft sand preferred
  • Water: Clean, stable conditions

Pair with

  • Peaceful tetras and rasboras
  • Soft sand substrate
  • Driftwood and planted aquascapes
  • Bottom feeder pellets
  • Other peaceful Corydoras species
NTA Insight:
Corydoras do best when treated as social fish rather than “cleanup crew.” Proper feeding and soft substrate make a far bigger difference than many hobbyists realise.

FAQ

Can I keep just one?

No. Corydoras are social fish and should be kept in groups for natural behaviour and reduced stress.

Do they clean the tank?

They help consume leftover food but are not a replacement for maintenance or cleaning.

Do they need sand?

Soft sand is preferred because it protects their sensitive barbels while foraging.

Are they beginner-friendly?

Yes. They are generally hardy when kept in clean water and appropriate groups.

What do they eat?

They prefer sinking pellets, wafers, frozen foods, and protein-rich bottom-feeder diets.

    Live Arrival & Ordering FAQ

    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.
