Is this for you?

βœ”οΈ Perfect if:

  • You want a brilliantly coloured feature fish.
  • You enjoy planted aquariums with gentle water movement.
  • You can provide a secure, tightly fitted lid.
  • You're interested in breeding unique freshwater fish.

❌ Avoid if:

  • Your aquarium does not have a secure lid.
  • You keep large, aggressive or highly competitive fish.
  • You want a species that thrives in strong water flow.
  • You cannot maintain stable water quality.

Why choose Gardneri Killifish?

Gardneri Killifish are admired for their vivid colouration, with mature males displaying electric blue or green bodies covered in red spots and markings, often complemented by bright yellow or orange fin edges. Females are more subdued but remain attractive, with a soft brown or olive appearance and subtle spotting.

Unlike annual killifish species, Fundulopanchax gardneri is a non-annual killifish and can live for several years when maintained under suitable conditions. This makes it one of the more approachable killifish for aquarists who are new to the group.

They are confident, curious fish that spend much of their time exploring the upper and middle levels of the aquarium. A heavily planted setup with floating plants, shaded areas and gentle filtration helps them feel secure and display their best natural behaviour.

  • Spectacular blue, red and yellow colouration
  • Hardier than many other killifish species
  • Excellent feature fish for planted aquariums
  • Interesting courtship and breeding behaviour
  • Suitable for species tanks and peaceful communities
  • Non-annual killifish with a longer natural lifespan

Care made simple

  • Temperature: 21–26Β°C
  • pH: Approximately 6.0–7.5
  • Diet: Quality micro pellets, flakes, frozen foods and live foods
  • Water: Clean, stable and well-filtered with gentle water movement
  • Setup: Heavily planted aquarium with floating plants, hiding places and open swimming areas
  • Lid: A tight-fitting lid is essential because killifish are excellent jumpers.
  • Perform regular partial water changes to maintain excellent water quality.

Pairs perfectly with

  • Small Corydoras
  • Otocinclus
  • Peaceful Rasboras
  • Small Tetras
  • Other similarly sized peaceful fish
NTA Insight:
Gardneri Killifish are exceptional jumpers and can escape through surprisingly small gaps. Always use a tightly fitted lid and cover openings around filters, cables and airline tubing. For the strongest colour and breeding condition, offer a varied diet that includes frozen or live foods such as brine shrimp, daphnia and blackworms.

FAQ

How big do Gardneri Killifish grow?

Adults generally reach approximately 5–7 cm, with males often developing a slightly larger and more colourful appearance than females.

Are Gardneri Killifish suitable for beginners?

They are among the hardier killifish and can suit experienced beginners who can maintain stable water conditions, provide appropriate foods and use a secure aquarium lid.

Can Gardneri Killifish live in a community aquarium?

Yes, provided their tank mates are peaceful, similarly sized and not overly competitive at feeding time. Avoid aggressive species and fish known for fin-nipping.

Do Gardneri Killifish need live food?

They can accept quality prepared foods, but regular frozen or live foods help improve colour, condition and breeding success.

Are Gardneri Killifish annual fish?

No. Fundulopanchax gardneri is a non-annual killifish, meaning its eggs do not require a prolonged dry period and adults can live for several years with proper care.

Will Gardneri Killifish breed in the aquarium?

Yes. They commonly deposit eggs in fine-leaved plants, spawning mops or moss. Adults may eat eggs or fry, so breeders often collect the eggs or move the spawning medium to a separate hatching container.

    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.
