FAQ

Are Twig Catfish good algae eaters?

They graze on soft algae and biofilm but should never be relied upon solely for algae control. They require regular feeding with algae wafers, spirulina foods, vegetables and supplementary prepared foods.

Why do they look like sticks?

Their remarkable body shape is an evolutionary adaptation that allows them to blend into submerged branches and driftwood, helping protect them from predators in the wild.

Are Twig Catfish suitable for beginners?

They are better suited to aquarists with some experience, as they require mature aquariums, consistently excellent water quality and careful feeding.

Can they live with shrimp?

Yes. Twig Catfish are exceptionally peaceful and are generally safe with adult freshwater shrimp and most dwarf shrimp species.

Do they need driftwood?

Absolutely. Driftwood provides resting surfaces, natural grazing areas and security, while also helping create the environment these fish naturally inhabit.

Can more than one Twig Catfish be kept together?

Yes. They are peaceful toward one another and can be kept in small groups when the aquarium provides adequate grazing surfaces and sufficient space.

How long do Twig Catfish live?

With excellent water quality, a mature aquarium and a varied diet, Farlowella Twig Catfish commonly live between 6 and 10 years.

What aquarium size is it suitable for?

    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.
