[ARRIVED 15-OCT-2025] C123 Yellowfin Corydoras Elegans 2-4cm

Description

C123 Yellowfin Corydoras Elegans

Elegant spotted Corydoras featuring silver body patterning and warm yellow fin highlights for peaceful community aquariums

Quick Facts

  • Scientific Name: Corydoras sp. C123
  • Common Name: Yellowfin Corydoras / Elegans Cory
  • Adult Size: Approx. 5–6 cm
  • Tank Size: 75L+ recommended
  • Difficulty: 🟒 Easy to Moderate
  • Temperament: Peaceful schooling bottom-dweller

Is this for you?

βœ”οΈ Good if:

  • You enjoy Corydoras groups and schooling behaviour
  • You keep planted community aquariums
  • You want an elegant bottom-dwelling fish
  • You provide soft substrate and stable water

❌ Avoid if:

  • You keep sharp gravel substrate
  • You want a solitary bottom fish
  • You house aggressive or territorial species
  • You expect them to survive on leftovers alone

Why this fish?

C123 Yellowfin Corydoras are admired for their refined silver body covered in delicate dark spotting, paired with subtle yellow tones in the fins.

This variety offers a more elegant appearance compared to heavily patterned Corydoras while maintaining the same peaceful personality and social behaviour.

They actively forage along the substrate, adding movement and natural behaviour to the lower level of the aquarium.

Key Features

  • Elegant silver body with spotted patterning
  • Yellow-tinged dorsal and tail fins
  • Peaceful schooling behaviour
  • Suitable for planted community tanks
  • Excellent bottom-level activity fish

Common mistakes

  • Keeping too few individuals
  • Using sharp gravel substrate
  • Expecting them to survive on scraps alone
  • Housing with aggressive tank mates
  • Poor water quality and dirty substrate

Care made simple

  • Temperature: 22–26Β°C
  • pH: 6.0–7.5
  • Water Hardness: Soft to moderately hard
  • Diet: Sinking pellets, frozen foods, wafers
  • Group Size: 6+ recommended

Feeding

  • Quality sinking pellets or wafers
  • Frozen bloodworms and brine shrimp
  • Occasional vegetable-based foods
  • Target feeding improves health and colour

Pair with

  • Peaceful tetras and rasboras
  • Dwarf cichlids
  • Planted aquariums
  • Other peaceful Corydoras species
  • Shrimp-safe community fish

Important Notes

  • Must be kept in groups for natural behaviour
  • Fine sand substrate strongly recommended
  • Will not replace regular tank cleaning
  • Yellow fin colour improves with quality diet
  • Plant-safe species suitable for aquascapes
NTA Insight:
Corydoras almost always behave better in larger schools. Groups of 6–10 usually display stronger confidence, better feeding response, and more visible social interaction.

FAQ

Groups of 6 or more are strongly recommended.

Do they need sand?

Are they peaceful?

Yes. They are excellent community fish.

Do they clean the tank?

No. They help scavenge food but still require proper feeding and maintenance.

Can they live with shrimp?

Yes. They are generally safe with adult shrimp and peaceful nano species.

    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.
