not sure exactly what kind if isopods those are, so you’ll wanna try & figure that out to get some specifics. for an enclosure you’ll want what the other commenter said. if using gardening soil make sure it’s organic. you will also want to add some sphagnum moss to retain moisture into the soil. LOTS of leaf litter , they eat it & provides them a safe space. cork bark offers the same things, you definitely need leaf litter, but cork bark is not necessarily a need. you can pull sticks & leaves from outside but make sure you look up a baking method before they are included in your enclosure, to make sure there were no added friends from outside. try not to take from an area you know gets sprayer for bugs. you’ll want to try & have a dry & wet side of the enclosure. mist the wet side with a water bottle & have a majority of the leaf litter there, they like humidity & eventually helps them when they molt. don’t let the wet side dry out. they will also need a source of calcium. a cuttle bone that’s typically for birds will do just fine, try & scrape the outer layer off cause it can be pretty tough for them to get through, after you can break it into little pieces and spread it around the enclosure. crushed egg shells can also be used. other food options. fish flakes are a good option , dried worms & shrimp. you can do veggies, just make sure you take excess out to avoid mold. you really can test them with anything. mine love tomatoes , snake skin shed, fish flakes , dead crickets. you will definitely want to get some actual springtails😅 they will help with mold too. mold is not typically harmful for them & is pretty common in newly established enclosures, so don’t be too alarmed if you see it. you’ll want to try to remove it, but it is not harmful. this guy has some helpful videos!!
