Note: Porcellio expansus, commonly known as the Giant Spanish Isopod, is a sizable isopod species native to northeast Spain. They thrive in environments that offer a balance between dry and moist areas, facilitated by good airflow and ventilation. Providing ample space is essential, as adult males can be territorial. A substrate rich in decaying organic matter supports their health and encourages breeding. Supplementing their diet with protein sources, such as fish flakes, freeze-dried shrimp, and vegetables like zucchini and carrot, supports their health and breeding success. Maintaining appropriate temperature and humidity levels is crucial for their well-being.
