When I ordered a small quanity of 15 Israeli Carp and some turtles from Zetts in PA they were shipped to IN in a plastic bag with water and oxygen in them and those were in a cardboard box. The fish and turtles were all alive, but you should let your post office know that you have live fish coming so they can notify you. I didn't do that but the fish were still OK when I picked them up.
