Is this for you?

Why this media bag?

The Seachem Zip Bag – Small is designed to securely contain finer filtration media while allowing efficient water flow through your filtration system.

Its ultra-fine 25 mesh construction makes it especially useful for smaller media particles that may escape from standard mesh bags.

The corrosion-resistant zipper offers a more secure alternative to traditional drawstring bags, helping reduce spills during maintenance.

Common mistakes

  • Using oversized bags in small filter compartments
  • Not rinsing media before use
  • Skipping maintenance cleaning
  • Using incorrect mesh size for intended media

Use made simple

  • Fill with desired filtration media
  • Zip securely closed
  • Place inside filter chamber or sump
  • Allow water to flow through naturally
  • Clean and reuse during maintenance

Pair with

  • Seachem Purigen
  • Fine activated carbon
  • Resin filtration media
  • Small-particle chemical filtration
  • Canister and sump filtration systems
NTA Insight:
Smaller mesh bags are especially useful when using premium filtration media. Preventing leakage of fine resins helps maintain filter efficiency and reduces maintenance mess.

    Live Arrival & Ordering FAQ

    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.
