Cash only please "These tiny creatures are excellent cleaners and can help to maintain a healthy and thriving ecosystem in your terrarium. Decomposition: By consuming decaying matter, they break down complex organic materials, recycling nutrients back into the soil." Isopods are easy to care for. They need a humid enclosure(by misting the inside walls) with a damp side, with bark, dirt and leaf litter. Moss is a bonus. With the right diet and environment: a protein and calcium sourse, leaf litter and veggies, they breed pretty fast and make unique pets or can breed them for feeders and/or bioactive setups. Any questions just ask! :)
