HCA: Hermit Crab Association

You can start a separate colony or just keep adding them to your tank. I like to start a separate one in a KK so I always have extras available. Don't collect any that are bright blue or purple, or otherwise discolored. They may have a virus that has the potential to spread to other arthropods. Not...

So..um...I can use Pillbugs to keep my crabitat clean? Do I just go gather some and stick them in the cage, or is there something specific I need to do? I don't use any chemicals outside- pure organic person- and we live in the middle of no where.
