[ARRIVED 13-JAN-2026] Corydoras oiapoquensis 3-4cm

Description

Corydoras oiapoquensis (Oiapoque Corydoras)

Peaceful bottom-dweller for established community and nano tanks

Quick Facts

  • Size: ~5–6 cm
  • Tank size: 40L+ recommended
  • Difficulty: 🟒 Easy
  • Temperament: Peaceful
  • Best kept: Groups (4–6+)
  • Plant safe: Yes

Is this for you?

βœ”οΈ Good if:

  • You want a peaceful bottom-dwelling fish for a community tank
  • You have a planted or nano setup with soft substrate
  • You are happy to keep a group of corydoras
  • You want active but non-aggressive fish

❌ Avoid if:

  • You want a β€œcleaner fish” that survives on leftovers
  • You plan to keep them alone
  • You use sharp gravel substrates
  • You keep aggressive or highly competitive fish

Why this fish?

Corydoras oiapoquensis is a peaceful, active bottom-dweller that brings constant movement and natural behaviour to the lower levels of the tank.

Like other Corydoras, they sift through the substrate for food, helping keep the tank active without disturbing plants or aquascaping.

Common mistakes

  • Keeping them alone instead of in a group
  • Expecting them to survive on leftover food
  • Using sharp gravel β†’ damages barbels
  • Overstocking the bottom of the tank
  • Assuming they replace proper tank maintenance

Care made simple

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

Pair with

  • Sinking pellets / bottom feeder food
  • Fine sand substrate
  • Driftwood and plants
  • Peaceful nano and community fish
NTA Insight:
Corydoras thrive when kept in groups and given proper food β€” most issues come from underfeeding and poor substrate choice, not the fish itself.

FAQ

Can I keep just one?

No. Corydoras are social fish and should be kept in groups of at least 4–6.

Do they clean the tank?

No. They help pick up leftover food but still require proper feeding.

Do they need sand?

Soft sand is preferred to protect their barbels, though smooth substrate can also work.

Are they good for beginners?

Yes. They are hardy and peaceful, making them suitable for most community tanks.

What do they eat?

Sinking pellets, wafers, and frozen foods such as bloodworms or brine shrimp.

    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.
