Premium Bioactive Clean-Up Crew Isopods, Springtails & Custodians

Looking for bioactive clean-up crews in the UK? At Micro Exotics, we offer a wide range of custodians including isopods, springtails, millipedes, worms and other beneficial invertebrates to help create thriving bioactive terrariums and vivariums.

Whether you're building a tropical terrarium, bioactive vivarium, paludarium or planted enclosure, custodians are an essential part of maintaining a healthy, self-sustaining ecosystem.


What Are Custodians?

The term custodian simply means caretaker, and that's exactly the role these fascinating creatures perform within a bioactive setup.

Often referred to as clean-up crews, custodians work tirelessly beneath the surface to break down waste, recycle nutrients and support plant growth. They form the foundation of a balanced ecosystem, helping to keep your enclosure clean while reducing the build-up of decaying organic matter.

From beginner terrariums to advanced bioactive reptile and amphibian enclosures, custodians are one of the most important components of a successful setup.


Why Add a Bioactive Clean-Up Crew?

Bioactive custodians provide a range of benefits, including:

  • Breaking down dead leaves and plant matter
  • Consuming decaying wood and organic waste
  • Processing animal faeces
  • Recycling nutrients back into the substrate
  • Supporting healthy plant growth
  • Helping to reduce mould outbreaks
  • Improving soil structure and aeration
  • Creating a more natural ecosystem

Species such as springtails are particularly effective at consuming mould and fungal growth, making them one of the most popular clean-up crew species available.

As custodians process waste, nutrients are returned to the substrate where they can be utilised by plants, helping create a truly self-sustaining environment.


More Than Just a Clean-Up Crew

Many custodian species are beautiful display animals in their own right.

From colourful tropical isopods to giant millipedes and active beetles, these fascinating invertebrates add movement, biodiversity and natural behaviours to your terrarium. Many species breed readily in suitable conditions and can establish thriving colonies that continue supporting your ecosystem for years to come.

Several species can even be kept together, allowing you to create diverse and visually stunning bioactive communities.


Important Before You Buy

Always ensure your terrarium or enclosure has adequate ventilation before introducing custodians.

Good airflow is essential for maintaining healthy populations and preventing excessive moisture build-up.


Isopods
 
Isopods are a group of crustaceans that include woodlice and pillbugs, isopods can be found in both marine and fresh waters as well as on land.
there are some 10,000+ species of  isopod with over half of these being found on land and we are still discovering new species all the time. Infact some of the most sought after species are so new to science they have not even been given a scientific name yet!

Isopods make the perfect addition to our terrariums, they feed mostly on decaying wood and leaves and will also eat the faeces of other animals, breaking these down into usable nutrients for our terrarium plants. Most species are easy to care for requiring no extra heating or lighting and only minimal supplementary feeding.

Many species  will breed readily, carrying their young in marsupial like pouches until they are ready to fend for themselves. Some species will also show very high levels of parental care,which is fascinating to watch.

Some species are very showy, whilst others shy away from light, they can vary considerably in size, shape and colour. in recent years hobbyists have even begun to create new colour strains called 'morphs', these morphs have been selectively bred over generations to improve colour and shape.
