Porcellio spatulatus
Spatulatus is the Isopod King culture listed as Porcellio spatulatus. This care sheet belongs to that species listing, not to a similarly shaped Porcellio. Confirm source-colony conditions with our keeper team before moving an established culture to a different environment.
This sheet belongs to the matching Isopod King listing. Check its selected count and current availability before ordering; the care guide does not change the product's options or shipping terms.
Build the stronghold
A refuge beneath the leaves
Provide generous floor space, suitable food-bearing substrate, deep leaf cover and stable bark shelters. Screen ventilation openings and offer ample airflow above the habitat. Use a sheltered moss pocket at one end, leaving the remaining covered surface drier.
Choose clean, pesticide-free materials and substrate without fertilizer or other chemical additives. Do not rely on plain coco fiber as the whole food supply. Secure ventilation openings against escapes, place the enclosure away from direct sun, and prepare it before the animals arrive.
Give them a choice
Two paths through the habitat
Keep a localized damp retreat rather than wetting the entire enclosure. This dry-leaning species still needs access to moisture. Check beneath the shelter and preserve the gradient as room conditions change; avoid stagnant, waterlogged bedding.
Air humidity alone cannot tell you whether the substrate under a hide is suitable. Check the refuge gently, keep cover in place, and adjust watering to ventilation and room conditions. Small juveniles need nearby sheltered moisture too.
Stock the royal pantry
Provisions for a living colony
Keep decaying leaves and suitable rotten hardwood in the enclosure. Offer modest protein and vegetable supplements in a place you can inspect, removing uneaten material promptly. Check available cover and food access as adults grow.
A suitable calcium source, such as cuttlebone, should remain accessible. Fresh and protein foods supplement the habitat's decaying plant material. Remove spoiled leftovers, reduce the next portion when food persists, and keep an eye on leaf cover as the colony grows.
Steady care, patient growth
Take up the colony watch
On arrival
Have the enclosure ready before opening the shipping container. Follow our arrival and acclimation guide, and give the colony a quiet place to settle.
During maintenance
Check moisture, leaf cover, leftovers and airflow. Observe a familiar shelter without overturning every hide. Record refuge moisture, ventilation changes and where the animals gather without repeatedly disturbing their shelters.
Give pale or molting animals space and avoid peeling away old shell. Females carry developing young in a brood pouch; growth varies with age, conditions and the starting group. Do not expect a fixed breeding timetable. Never release captive isopods outdoors.
A role in the living habitat
Every companion has a place
Keep Spatulatus as its own labeled display colony initially. A consistently wet tropical enclosure may not provide the ventilation and drier area it needs. Maintain a separate reserve colony and evaluate the full habitat before using it as a cleanup crew.
Continue removing excessive waste and checking the needs of every inhabitant. A cleanup crew supports routine care; it does not replace it.
Observe before you adjust
Read the signs along the trail
| What you notice | First checks |
|---|---|
| Refuge drying out | Inspect beneath the moss; restore moisture gradually without flooding. |
| Mold on fresh food | Remove leftovers and review portion size, water and airflow. |
| An overheated enclosure | Check sunlight and nearby heaters; protect the culture from heat. |
| Repeated losses | Record conditions and recent changes. Send clear photos to our keeper team. |
These are habitat checks, not diagnoses. If problems continue, ask Isopod King for help before making several large changes at once.
From the keeper’s camp
Questions along the journey
Can the whole enclosure stay dry?
No. Dry-leaning care means a choice between a sheltered moist refuge and drier, ventilated areas. Complete dryness removes the retreat needed for hydration and vulnerable young.
How often should I water?
Use the condition of the damp refuge as your guide. Ventilation, substrate depth and room conditions change how quickly it dries, so check it and water selectively instead of following one fixed schedule.
Where can I continue learning?

Your colony’s ongoing story
Record refuge moisture, ventilation changes and where the animals gather without repeatedly disturbing their shelters. A few short notes on watering, feeding, molts and enclosure changes help reveal patterns without constant disturbance.
- Keep a usable damp refuge.
- Replenish leaves, suitable wood and calcium.
- Remove spoiled supplements.
- Record changes and ask for help when needed.
