Description

Gold Laser Corydoras (Corydoras sp. CW010)

Bright gold-stripe cory with strong group behaviour for established aquariums

Quick Facts

  • Size: ~5–6 cm
  • Tank size: 60L+ recommended
  • Difficulty: 🟡 Moderate
  • Temperament: Peaceful
  • Best kept: Groups (5+)
  • Plant safe: Yes

Is this for you?

✔️ Good if:

  • You want a standout Corydoras with strong visual appeal
  • You have a stable, established tank
  • You enjoy keeping fish in proper groups
  • You keep peaceful community species

❌ Avoid if:

  • Your tank is newly set up or unstable
  • You want a single “feature fish”
  • You expect them to clean your tank
  • You keep aggressive or highly competitive fish

Why this fish?

Gold Laser Corydoras are known for their striking metallic gold stripe that runs along the body, making them one of the most eye-catching Corydoras available.

When kept in groups, they display natural schooling behaviour and become far more active and visually impressive.

Common mistakes

  • Keeping them in small numbers instead of a group
  • Buying them for appearance but not meeting care requirements
  • Adding to unstable tanks → higher stress and losses
  • Using sharp substrate → damages barbels
  • Underfeeding due to “bottom feeder” assumptions

Care made simple

  • Temperature: 22–26°C
  • Diet: Sinking pellets, wafers, frozen foods
  • Group size: 5+ recommended
  • Substrate: Soft sand preferred
  • Water: Clean, stable, well-maintained

Pair with

  • Sinking cory pellets or wafers
  • Fine sand substrate
  • Driftwood and plants
  • Peaceful tetra, rasbora, or nano fish
NTA Insight:
These look best and behave naturally when kept in proper groups. Most issues come from keeping too few or adding them to unstable tanks.

FAQ

Are Gold Laser Corydoras beginner-friendly?

Suitable for beginners with an established tank, but not ideal for brand-new setups.

Can I keep just one or two?

Not recommended. They are social fish and should be kept in groups of at least 5.

Do they clean the tank?

No. They forage along the bottom but still require proper feeding.

Do they need sand?

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

Why are they called CW010?

CW numbers are hobby codes used to identify Corydoras that are not formally described 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.
