Hey everyone! I am trying to find new shells for my dwarf zebra hermit crab in my tank. He is currently really small and was wondering if anyone has any advice for what kinds of shells that he might want to get into? Any website link would be greatly appreciated! I bought some shells from ebay (and they tag it as small but when I got it, it looked pretty big. My hermit plays with it but never went into it). Anyone have any suggestions? Round holes or oval? Any help would really be appreciated!
