🔍 At A Glance: Tropical Grey Isopod Husbandry Summary
Scientific Name: Porcellionides pruinosus (Tropical Grey / Powder Blue Morph)
Adult Size & Lifespan: 9–15mm | Adults live for 2–3 years
Breeding & Growth Rate: Exceptionally prolific with rapid population growth; utilizes high-speed reproduction to establish massive numbers within a few months.
Ideal Climate: Temperature: 21–27°C (22–23°C kept The EntoScapes Way for best results) | Humidity: 60–80% (70–80% preferred The EntoScapes Way)
Physical Identification & Behaviour: Elongated, soft-bodied oval shape covered in a specialized, waxy "pruinose" coating that creates a distinct matte, dusty blue iridescent sheen. Extremely agile, lightning-fast scavengers that actively forage both above and within the substrate.
Place of Origin: Originally native to the Mediterranean region; now a highly successful cosmopolitan species distributed worldwide.
Enclosure Sizing Guide: Smaller starter groups thrive perfectly within a compact 20x15x15cm environment; large master breeding colonies scale up cleanly into a 40x20x20cm setup.
Dietary Base: Heavy detritivore essentials reliant on a high-quality base of hardwood leaf litter (oak, beech, hazel), decaying wood, flake soil, organic waste, and sphagnum moss.
Supplemental Nutrition: Weekly fresh vegetables (slices of cucumber, squash, or sweet potato) paired with a weekly high-protein source (fish flakes, shrimp pellets, or nutritional yeast) and a constant separate supply of calcium (crushed cuttlebone, sepia, or eggshells).
Perfect For Live Food: Powder Blues are a soft-bodied prey species with a delicate exoskeleton, making them highly digestible and rich in calcium as an excellent supplemental food source.
Important Safety Note: However, because they can be protein-hungry, we recommend not keeping them with millipedes, as they can sometimes nibble on them while they are vulnerable and moulting.
At EntoScapes, our Powder Blues are UK captive-bred and raised on our mineral-rich leaf litter substrates to ensure they arrive active, healthy, and ready to populate your ecosystem.
