The crowd-favorite workhorse. Dairy Cow isopods (Porcellio laevis) are big, bold, and remarkably fast-breeding, and their black-and-white spotted pattern earns them their barnyard nickname. They are a beginner favorite for good reason.
Few isopods reproduce as quickly or clean as voraciously. They tear through decaying matter and waste, which makes them a powerhouse cleanup crew and an excellent, protein-rich feeder for reptiles and amphibians.
- Very fast breeders and a high-value colony
- Aggressive detritus and waste processors
- Large, striking, and easy to keep
- Doubles as a premium feeder isopod
