When I was in Grade 8/8th Grade I had pet land hermit crabs which I bought at a local pet store. Me and my brother had a total of 6 crabs, which lasted like 2 years.
If you've been watching "Survivor: Pearl Islands" on CBS you can see them once in awhile. They invaded the Morgan camp on the first night.
It would be cool to bring back my old hobby and combine it with my new CP hobby and have them in a terrarium with CPs or would it be a disaster and they would be just another meal for the plants after a few days?
