Oreo Crumble Porcellionides pruinosus 'Oreo Crumble'

Porcellionides pruinosus 'Oreo Crumble' is a selectively bred pied morph mutation of the pruinosus. The result is a white-to-cream base adorned splotches in patterns that vary between individuals. Fast, prolific, and beginner-friendly, it shares all the reliable traits of the pruinosus line while offering a striking color combination that stands out in any setup. Excellent for bioactive vivariums, display cultures, and as a soft-bodied feeder for smaller reptiles and amphibians.

Substrate mix: For best results, use Isopod Paradise Organic Substrate specifically formulated to support healthy colonies. If you would rather mix your own, we recommend a blend of 70% organic topsoil, 10% flake soil, 10% milled sphagnum moss, 8% organics(mushroom compost, earthworm castings and leaf litter) and 2% calcium

Hides & decor: Bark, rotting hardwood pieces, generous hardwood leaf litter. They are fast and will use hides primarily to regulate moisture rather than for long-term shelter.Cuttlebone for calcium source.

Moisture: Maintain a moisture gradient with roughly half the enclosure damp and half dry. P. pruinosus is highly adaptable — it tolerates both semi-arid and humid setups — but consistent moisture access is needed for healthy molting. Add springtails to manage mold from heavy feeding activity.

Enthusiastic, wide-ranging feeders. When protein is offered, they respond dramatically — clustering over food almost like a swarm. Protein once per week is adequate; more frequent offerings speed reproduction.

Feeding frequency:Rotate foods on a weekly basis. Remove leftover food when food begins to mold. Leaf litter and rotting wood can remain as a continuous background food source.

One of the fastest-reproducing isopods in the hobby. Colonies build rapidly under good conditions, and the pied coloring produces variable, interesting patterns in the offspring. Females carry young in a marsupium and give live birth; mancae are immediately active and fast.

Mancae care: Juveniles emerge tiny but fully formed and active. Offer fine food on the substrate surface. Their small size makes them ideal food for dart frogs and small reptiles — plan accordingly if mixing with vivarium inhabitants.

Colony tips: A group of 20 can become a thriving colony within 3–4 months. Oreo Crumble coloring is variable — not all offspring will show strong orange patterning. This is natural variation, not a health issue.
