The best thing I can tell you is to go shopping online. If you have Purple Pinchers, they tend to like turbo shells and shells with a snail shape. If you have a Walmart or a craft store, check to see if they carry shells. Sometimes you can find bags of mixed shells and there will be some usable shells in the mix. Sometimes you can find them at "dollar stores" too. YOu can boil the assorted shells and use them as tank decorations.
