Arcadia EarthPro Custodian Fuel 80g – Bioactive Microfauna & Isopod Diet

Arcadia EarthPro Custodian Fuel is a natural, nutrient-rich pelleted diet designed to feed and strengthen microfauna in bioactive enclosures. Suitable for springtails, woodlice, isopods, mealworms, earthworms, white worms, small beetles and millipedes, it provides a clean, balanced whole-food source that promotes strong colonies and efficient waste breakdown.

Bioactive custodians form the core of any living substrate. By feeding and multiplying these organisms, Custodian Fuel helps maintain a healthy micro-ecosystem that supports waste recycling, soil aeration and long-term terrarium stability. Growing more springtails and isopods also benefits small reptiles and amphibians, as many species naturally consume microfauna as part of their diet.

The pellets are designed to be pressed into the substrate, where they slowly break down into a nutrient-rich soup that microfauna readily feed on. This method keeps the food out of sight, avoids mould formation, leaves no white residue and provides consistent nutrition across the enclosure.

Custodian Fuel can also be used as a gut-loading food, improving the nutritional value of isopods, roaches and other small invertebrates when they are consumed by reptiles or amphibians.

Key Features:

• Natural dietary pellet for bioactive custodians & microfauna
• Supports springtails, isopods, woodlice, beetles, worms & roaches
• Breaks down into a nutrient-rich substrate food source
• No mould, no white residue, clean and easy to use
• Promotes strong colonies for efficient waste breakdown
• Also suitable as a gut-loading food for reptiles & amphibians

Feeding Instructions:

Press Custodian Fuel pellets into the substrate approximately every 25mm until fully hidden. They will break down naturally into a nutrient-rich soup that feeds microfauna. Repeat every 7–14 days depending on colony size and enclosure conditions.

Suitable For:

• Springtails
• Tropical & European woodlice
• Isopods
• Mealworms & earthworms
• White worms
• Fruit beetles
• Small millipedes
• Other bioactive custodian species

Frequently Asked Questions:

How do I use Custodian Fuel in a bioactive enclosure?
Press the pellets slightly below the surface of the substrate. They will break down naturally and feed the microfauna.

Will Custodian Fuel cause mould?
No. The formulation is designed to break down cleanly with no white residue or mould formation.

Which species benefit from Custodian Fuel?
It supports springtails, isopods, woodlice, worms, beetles and other common bioactive custodians.

Can reptiles eat custodians fed with this?
Yes. Custodian Fuel also works as a gut-loading diet, improving the nutritional value of microfauna eaten by reptiles or amphibians.

How often should I feed my custodian colonies?
Every 7–14 days depending on colony density and bioactive system activity.
