[ARRIVED 10-APR-2026] Premium Fish Isolation Box

Description

Premium Acrylic Fish Isolation Box

Clear, hang-on isolation box for safe fish separation, acclimation, and monitoring

Quick Facts

  • Material: High clarity acrylic
  • Mounting: Hang-on design (fits up to approx. 23mm glass)
  • Water Flow: Mesh side panels
  • Use: Isolation / acclimation / breeding
  • Compatibility: Most standard aquariums
  • Visibility: Clear viewing for monitoring fish

Is this for you?

✔️ Good if:

  • You need to isolate sick or injured fish
  • You want to safely introduce new livestock
  • You need temporary separation for aggression or breeding
  • You want to monitor fish without removing them from the tank

❌ Avoid if:

  • You expect it to replace a quarantine tank
  • You need permanent housing for fish
  • Your tank rim exceeds mounting thickness
  • You want a fully self-contained filtration system

Why this product?

This acrylic isolation box allows you to separate fish while still keeping them within the same water system.

Because it shares the aquarium’s water conditions, fish experience less stress compared to moving them into a completely different environment.

The clear acrylic design makes it easy to observe behaviour, monitor recovery, or safely acclimate new arrivals before full release.

Common mistakes

  • Using it as long-term housing → can increase stress
  • Overcrowding multiple fish into one box
  • Ignoring debris buildup or poor water movement
  • Assuming it replaces proper quarantine procedures
  • Leaving aggressive fish within constant visual range too long

Use made simple

  • Hang securely onto aquarium edge
  • Ensure mesh panels remain clear for water movement
  • Use for short-term observation or acclimation
  • Monitor fish regularly during isolation
  • Remove fish once purpose is complete

Pair with

  • Fish nets for safe transfer
  • Water conditioner (e.g. Prime)
  • Air stone for added circulation
  • Hospital tank setup for extended treatment
NTA Insight:
Isolation boxes are one of the most underrated tools in fishkeeping. They are ideal for aggression management, recovery, breeding separation, and introducing sensitive livestock safely.

FAQ

Is this a quarantine tank?

No. It is designed for short-term isolation inside an existing aquarium, not full quarantine.

Can I keep fish inside long term?

It is best used temporarily. Long-term housing may create stress due to limited space.

Does water circulate through the box?

Yes. Mesh side panels allow aquarium water to flow through while keeping fish separated.

What can I use it for?

Isolation, acclimation, aggression management, breeding separation, and observation.

Will it fit my tank?

It fits most aquariums up to approximately 23mm glass thickness.

    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.
