Why We Recommend a 10L Bin for Your First Isopod Setup

Choosing the Right Size Isopod Enclosure

When people first start keeping isopods, one of the most common questions is what size enclosure to use. You’ll often see very small containers like 3-litre or 5-litre boxes recommended online. While these can work, they’re usually better suited to experienced keepers.

For most people, we recommend starting with a 10-litre enclosure.

The reason is simple: stability

Small bins can be surprisingly difficult to manage. They dry out faster, humidity swings more quickly, and conditions can change dramatically in a short period of time. This means they often require frequent monitoring and very small adjustments to keep things balanced.

In practice, smaller enclosures can turn into something that needs constant micro-management.

A 10L bin creates a much more stable environment. Moisture levels change more slowly and the substrate holds humidity more effectively, making it easier to maintain the wet and dry sides that isopods rely on.

More space for a healthier ecosystem

The extra space also allows for deeper substrate, which supports microbial life and helps process waste naturally. It also gives isopods room to burrow and behave more naturally.

You also gain more vertical space for cork bark, leaf litter, and climbing surfaces. This not only improves the habitat for the isopods but also makes the enclosure easier to maintain.

If you're setting up your first enclosure, purpose-built containers like our vented isopod enclosures are designed to provide the airflow and space needed to create a stable environment for most species.

You can also explore other materials typically used in isopod enclosures and supplies, including cork bark, leaf litter, substrate mixes and calcium sources.

Less frequent maintenance

Another advantage is maintenance intervals. Larger setups generally require less frequent intervention because the ecosystem has more room to balance itself.

In simple terms

• Small bins are precise instruments.
• Larger bins are stable ecosystems.

For beginners especially, that extra margin for error makes the hobby far more enjoyable.

If you're just getting started, consider beginning with hardy species such as Zebra Isopods or Cubaris Murina, which are often recommended as beginner-friendly isopods.

That’s why at isopods.co.uk we generally recommend 10 litres as a sensible starting point for most species.
