FAQ

What is a Wrestling Halfbeak?

Wrestling Halfbeaks are small livebearing surface fish belonging to the Dermogenys group. The name comes from the displaying and sparring behaviour sometimes seen between males.

Why are they called Halfbeaks?

The lower jaw extends significantly beyond the upper jaw, creating the distinctive “half-beak” profile.

Is Platinum a separate species?

No. Platinum describes the selectively bred pale metallic colour form rather than a separate species.

How large do Platinum Wrestling Halfbeaks grow?

Adults generally reach approximately 5–7 cm, depending on sex and the exact Dermogenys line.

Are Wrestling Halfbeaks aggressive?

They are generally peaceful towards unrelated community fish. Adult males may display, chase and spar with one another, particularly when competing for space or females.

Can I keep multiple males?

Yes, but only with sufficient surface area and visual cover. In smaller aquariums, male competition can become excessive, so reducing the number of males may be necessary.

Do Halfbeaks need floating plants?

They are not essential, but floating plants provide security and break up territories while leaving open areas for surface swimming.

What should I feed them?

Offer quality floating foods because Halfbeaks naturally feed near the surface. Small live or frozen foods such as baby brine shrimp, daphnia, mosquito larvae and suitable insects are excellent supplements.

What does Platinum Wrestling Halfbeak (Dermogenys sp.) do?

Platinum Wrestling Halfbeak (Dermogenys sp.) is intended for species-appropriate, established aquariums. Check the selected option and listing details against your needs.

What aquarium size is it suitable for?

Use any verified rating in the Specifications section as a starting point. If no rating is stated, contact NTA when tank size is the deciding factor.

Is this the right model for my aquarium?

Confirm purpose, physical fit, capacity and compatibility before ordering.

What's included in the box?

Only the selected product and components explicitly stated in the current listing are included.

    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.
