Quick Facts

  • Scientific name: Aphyosemion australe
  • Size: ~5–6 cm
  • Tank size: 30L+ recommended
  • Difficulty: 🟢 Easy to Intermediate
  • Temperament: Peaceful
  • Best kept: Pair or species group

Is this for you?

✔️ Good if:

  • You want a colourful, peaceful nano fish
  • You enjoy planted or blackwater aquariums
  • You appreciate unusual and elegant fish
  • You're interested in breeding killifish

❌ Avoid if:

  • You keep highly aggressive or fin-nipping fish
  • Your aquarium doesn't have a secure lid
  • You prefer fast-swimming community fish
  • You want fish that tolerate poor water quality

Why this fish?

The Chocolate Lyretail Killifish is a beautiful colour variety of Aphyosemion australe, admired for its warm chocolate-bronze body, vibrant finnage, and graceful lyre-shaped tail.

These peaceful fish thrive in well-planted aquariums with gentle water movement. They spend much of their time exploring the middle and upper levels of the aquarium and display their best colours under subdued lighting and against dark backgrounds.

Sold as a compatible male and female pair, they are an excellent choice for hobbyists interested in observing natural spawning behaviour or breeding one of the easiest killifish species.

Common mistakes

  • Leaving gaps in the aquarium lid—they are excellent jumpers
  • Keeping them with aggressive or fin-nipping fish
  • Using excessive water flow
  • Providing very bright lighting without plant cover
  • Allowing water quality to deteriorate

Care made simple

  • Temperature: 21–25°C
  • pH: 6.0–7.5
  • Diet: Quality micro pellets, frozen foods, live foods
  • Water: Clean, stable water with gentle flow
  • Setup: Well-planted aquarium with floating plants and a tight-fitting lid

Pair with

  • Peaceful nano fish
  • Freshwater shrimp (larger adults)
  • Floating plants
  • Botanicals and driftwood
  • Live or frozen foods
NTA Insight:
One of the biggest mistakes people make with killifish is underestimating their jumping ability. Aphyosemion australe can launch through surprisingly small gaps, so a tight-fitting lid is essential. Given the right environment, they're hardy, peaceful, and among the easiest killifish to breed.

FAQ

Why are these sold as a pair?

These fish display their best natural behaviours as a male and female pair, and they are one of the easiest killifish species to breed under suitable conditions.

Can they live in a community aquarium?

Yes. They do well with other peaceful nano fish, provided tank mates are not aggressive or prone to fin-nipping.

Do they jump?

Yes. Like most killifish, they are exceptional jumpers. A secure, tight-fitting lid is essential.

What do they eat?

They readily accept quality micro pellets, frozen foods such as bloodworms and brine shrimp, and live foods for optimal colour and conditioning.

Are they suitable for beginners?

Yes. While slightly more specialised than common community fish, Aphyosemion australe are considered one of the easiest killifish species to keep and breed when provided with clean water and a secure aquarium.

    Live Arrival & Ordering FAQ

    Why do livestock prices sometimes change?

    Unlike manufactured products, fish and shrimp continue to grow and develop over time. Their value changes as they increase in size, develop colour, or become breeding pairs.

    Our prices are based on the current size, quality and availability of each specimen. While pricing often remains stable for around 3–4 months, it may be updated at any time to reflect these changes.

    We always aim to offer healthy, high-quality livestock at fair and competitive prices.

    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.
