Care notes
Porcellio ornatus is a Mediterranean species that runs drier than most isopods — keep roughly 45–60% RH with a small humid retreat rather than a broad damp zone, and prioritize strong ventilation. Its a large, active species that benefits from protein and calcium to avoid cannibalism in tight quarters. A starter group takes a few months to build a visible population.
