Porcellio Laevis Crystal White Isopods

Porcellio laevis Crystal White isopods are a striking, selectively bred morph of the common dairy cow isopod, prized by keepers for their bright white coloration, fast growth and active behavior. These hardy terrestrial isopods are ideal for bioactive terrariums, naturalistic vivariums and as clean-up crews in reptile and amphibian enclosures, where they help maintain a healthy, low-maintenance environment.

Care and Habitat

Crystal White isopods thrive in a well-ventilated enclosure with a consistently moist substrate layer and plenty of secure hiding spots. A deep mix of coco fibre, leaf litter and decaying hardwood supports healthy colonies, encourages natural burrowing behaviour and provides a constant source of food. Maintaining stable room temperatures, a moisture gradient and moderate humidity helps preserve their vibrant white colour, promotes strong reproduction and supports long-term colony stability.

Diet and Benefits

These Porcellio laevis isopods feed on leaf litter, rotting wood, fish flakes, high-quality isopod diets and vegetable scraps, making them efficient decomposers in any bioactive setup. As part of a clean-up crew, they help break down organic waste, reduce mould, recycle nutrients and support a balanced micro-ecosystem for reptiles, amphibians and invertebrates. Their bright appearance, bold activity and large adult size also make them attractive display invertebrates that add movement and interest to display terrariums.
