I was afraid to order on-line also, but my LFS store in town is not very good with marine fish. I placed my first order last Monday and it arrived on Thursday. I got 4 percula clowns and 2 emerald crabs. When I opened the cooler that they ship in the fish were upright and swimming, not even breathing hard. They each had there own bag. I followed the directions for acclimation and then put them into my tank. They are the brightest colored and hyperactive clowns I have ever seen. I see no reason to buy from LFS in town anymore, besides there clowns were $45. You have nothing to worry about.
