Sunshine color from Spain. High Yellow isopods (Porcellio haasi) show a strong, saturated yellow across their plates, native to Spain and adapted to a drier, semi-arid environment than many isopods need.
This species does best with a good calcium supply and lower humidity levels compared to tropical isopods. It settles in well for keepers who already have some experience with dry-leaning Porcellio species.
- Strong, saturated yellow coloration
- Native to Spain
- Prefers a drier, calcium-rich setup
- Good next step for intermediate keepers
