Porcellio werneri
Silver Back is the name of this Isopod King culture, listed as Porcellio werneri. Keep the full culture label with your colony. Counts describe the group you order; they do not identify a different species or change its daily care. The named color or locality line belongs with its species identity; appearance can vary between individuals, ages and molts. Keep lines separate if you want to preserve their records.
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
Place stable cork slabs over food-bearing substrate and leaf litter, leaving low passages suited to a flattened animal. Provide several resting surfaces and adequate floor space. Lift shelters slowly during checks and never squeeze an animal between a hide and the enclosure wall.
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 one sheltered section of bedding damp while the opposite side remains less wet and ventilated. Check beneath the favored hide instead of relying on the exposed surface. Maintain covered routes between suitable resting areas and the moisture zone.
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 suitable decaying leaves and soft hardwood available. Trial small portions of supplemental vegetables and protein, checking which foods are used. Remove spoiled material and avoid burying fresh food under the main hide.
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. Note which low shelters are used and check for trapped animals before replacing cover.
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
A dedicated display culture makes this species’ shelter and moisture needs easier to monitor. Any mixed habitat must offer the same broad sheltered surfaces and a usable gradient, with a reserve culture maintained separately.
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.

Questions along the journey
Does the Silver Back name change the care routine?
Use the needs of Porcellio werneri as your starting point. The line name helps identify the culture, while moisture choice, shelter, food and stable conditions remain the foundations. Keep it separately labeled and confirm any source-colony differences before changing its setup.
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?
