I am trying to find some empty hermit crab shells to place in my tank. I have a few small hermit crabs and want to get some med-large shells. LiveAquaria only has large right now. Saltwaterfish.com sells them in lots of 50 or 100. I was going to get the 50 for 7.99 but then I saw that will all the fees I would end up paying over twenty dollars. Does anyone know where I can get some shells for a reasonable price?
