A very popular variant of a great species! Porcellio leavis tend to grow larger than most people might expect, and our largest are close to 2 cm in length. This is also an active species that breeds well, and is a great isopod for a bioactive "cleanup crew." Though they tolerate a wide variety of humidity levels and ventilation, they seem to to best in higher moisture. They also appear to love protein-rich foods, though they also love their share of tortoise chow and pumpkin!
