Why choose Hypsolebias coamazonicus?

NTA Insight:
Unlike non-annual killifish, Hypsolebias coamazonicus has evolved to survive seasonal droughts. In breeding programs, the eggs are often collected from peat or spawning substrate and incubated under controlled conditions before being rehydrated to hatch. Their fascinating life cycle is one of the reasons annual killifish are so highly regarded among specialist aquarists.

FAQ

How big does Hypsolebias coamazonicus grow?

Adults typically reach around 4–6 cm, with males displaying the brightest colours during breeding condition.

Is this species suitable for beginners?

No. This species is best suited to experienced aquarists due to its specialised care requirements and annual breeding cycle.

What does "annual killifish" mean?

Annual killifish naturally inhabit temporary pools that dry out seasonally. Their eggs survive the dry period before hatching when water returns, making their life cycle very different from most freshwater fish.

Can they live in a community aquarium?

They are best maintained in a species aquarium or with very carefully selected peaceful companions, as their specialised care requirements are easier to meet in a dedicated setup.

Do they require live food?

While many individuals accept frozen and prepared foods, regular live or frozen foods are strongly recommended to maintain excellent health, colour and breeding condition.

    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.
