A group of 15 captive-bred powder isopods, a clean-up crew for a bioactive terrarium. They are sold to work on leaf litter and other organic debris in the build.
Isopods suit a build that supports living creatures alongside plants. Use a lid or vent so they stay inside. Start with the full pack in one settled build rather than splitting it across several jars. Keep the build's moisture in mind, as isopods need it to stay active.
