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
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.
