[ARRIVED 10-JAN-2026] SUPER RARE: Corydoras Hastatus - The Dwarf Sedge Cory 1-2cm

Description

Corydoras hastatus (Tail Spot Corydoras)

Tiny schooling cory that spends most of its time in mid-water

Quick Facts

  • Size: ~2.5–3 cm
  • Tank size: 20L+ recommended
  • Difficulty: 🟡 Moderate
  • Temperament: Peaceful
  • Best kept: Groups (8–10+)
  • Plant safe: Yes

Is this for you?

✔️ Good if:

  • You want a nano schooling fish with unique behaviour
  • You enjoy mid-water activity in small tanks
  • You have a peaceful planted aquarium
  • You are happy to keep a larger group

❌ Avoid if:

  • You want a traditional bottom-dwelling cory
  • You plan to keep just a few
  • You keep larger or aggressive fish
  • You expect them to clean the tank

Why this fish?

Corydoras hastatus is one of the smallest corydoras species, known for its distinct tail spot and schooling behaviour.

Unlike most corys, they spend much of their time swimming in the mid-water in tight groups, making them more like a nano schooling fish than a typical bottom-dweller.

Common mistakes

  • Keeping them in small groups → leads to stress and poor behaviour
  • Expecting bottom-dwelling behaviour
  • Keeping with larger fish that intimidate them
  • Underfeeding due to their small size
  • Assuming they replace tank maintenance

Care made simple

  • Temperature: 22–26°C
  • Diet: Micro pellets, fine foods, small frozen foods
  • Group size: 8–10+ recommended
  • Substrate: Soft sand preferred
  • Water: Clean, stable, well-maintained

Pair with

  • Micro pellets / fine foods
  • Fine sand substrate
  • Dense plants
  • Small peaceful nano fish
NTA Insight:
This species behaves more like a nano schooling fish than a typical cory. The larger the group, the tighter and more natural their schooling behaviour becomes.

Are they good for nano tanks?

Yes, they are ideal for nano setups when kept in groups.

What do they eat?

Micro pellets, fine foods, and small frozen foods suitable for nano fish.

    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.
