[ARRIVED 26-MAR-2026] Corydoras Pygmaeus Pygmy 1-2cm

Description

Corydoras pygmaeus (Pygmy Corydoras)

Tiny, schooling cory that moves between bottom and mid-water in nano tanks

Quick Facts

  • Size: ~2–3 cm
  • Tank size: 20L+ recommended
  • Difficulty: 🟒 Easy
  • Temperament: Peaceful
  • Best kept: Groups (6–10+)
  • Plant safe: Yes

Is this for you?

βœ”οΈ Good if:

  • You want a nano-friendly schooling fish
  • You enjoy active movement across the whole tank
  • You have a peaceful planted aquarium
  • You are happy to keep a larger group

❌ Avoid if:

  • You want a strictly bottom-dwelling cory
  • You plan to keep just a few (too small group)
  • You keep large or aggressive fish
  • You expect them to clean the tank

Why this fish?

Corydoras pygmaeus is one of the smallest corydoras species, making it ideal for nano aquariums.

Unlike most corys, they regularly swim in the mid-water as a group, giving you both bottom activity and schooling behaviour in one fish.

Common mistakes

  • Keeping too few β†’ they need larger groups (6–10+)
  • Expecting them to stay only on the bottom
  • Keeping with larger fish that intimidate or outcompete them
  • Underfeeding due to small size
  • Assuming they replace tank maintenance

Care made simple

  • Temperature: 22–26Β°C
  • Diet: Fine sinking foods, micro pellets, frozen foods
  • Group size: 6–10+ recommended
  • Substrate: Soft sand preferred
  • Water: Clean and stable

Pair with

  • Micro pellets / fine sinking food
  • Fine sand substrate
  • Dense plants
  • Small peaceful nano fish
NTA Insight:
These are best treated as a nano schooling fish, not just a bottom cleaner. The larger the group, the more natural and active their behaviour becomes.

FAQ

Are they bottom dwellers?

Not exclusively. They spend time both on the bottom and swimming mid-water in groups.

How many should I keep?

At least 6, but 8–10+ is strongly recommended for natural behaviour.

Are they good for nano tanks?

Yes. They are one of the best corydoras species for nano setups.

Do they clean the tank?

No. They still require proper feeding and care.

What do they eat?

Fine sinking foods, micro pellets, and small frozen foods.

    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.
