I found it! I drove to the LFS (local fish store) tonight where they were purchased and asked the salesperson. She said they were selling them as Julii because they thought they were "immature" ones. I showed her how the Julii have a definite strip on their side, and the ones they were selling did not have stripes. She took out her big catalog of Cory pictures they can order, and sure enough, there were the 2 Cories that were purchased---SPOTTED CORIES!
Thanks for your input, everyone! I did find out at the LFS that if they don't have the fish you want---ask them. They can probably order them for you!
