Why choose Betta schalleri?

Unlike the familiar Siamese Fighting Fish, Betta schalleri is a naturally peaceful species that has evolved in quiet, tannin-stained rainforest streams. Mature fish display stunning metallic turquoise and blue-green iridescence across their body and fins, particularly under subdued lighting.

One of the highlights of this species is its unique paternal mouthbrooding behaviour. After spawning, the male carefully carries the fertilised eggs inside his mouth for around two weeks before releasing fully developed fry. This remarkable behaviour is one of the reasons wild Bettas are so captivating to keep.

Their calm temperament, natural beauty and fascinating behaviours make them a rewarding species for aquarists seeking something beyond the typical aquarium fish.

FAQ

Is Betta schalleri aggressive?

No. This species is considerably more peaceful than the common Siamese Fighting Fish and is often successfully maintained as compatible pairs or small groups in well-structured aquariums.

How do they breed?

Betta schalleri is a paternal mouthbrooder. After spawning, the male incubates the eggs inside his mouth until the fry are fully developed and ready to swim independently.

Do they need blackwater conditions?

They thrive in soft, acidic blackwater with tannins, although captive-bred specimens can adapt to stable soft water that closely matches their natural environment.

What do they eat?

They readily accept premium Betta pellets but thrive on a varied diet including frozen bloodworms, mosquito larvae, brine shrimp, daphnia and live foods.

Can they be kept in a community aquarium?

Yes, with small peaceful species that enjoy similar water conditions. Avoid fin nippers, large cichlids and fast-feeding fish.

How long do they live?

With proper care and stable water quality, Betta schalleri typically lives between 4 and 6 years.

Why are wild Bettas different from Siamese Fighting Fish?

Wild Bettas retain their natural appearance and behaviours. They are generally less aggressive, often display fascinating breeding strategies such as mouthbrooding, and are best appreciated in naturalistic aquariums rather than as ornamental display fish.

    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.
