For those of you who say Walmart has no control of how they are shipped, that is rubbish. I've worked for a factory that supplied Walmart, and a warehouse that stored Walmart stuff. Walmart was VERY particular in both cases and everything had to be just so. It had to be shipped in certain boxes, labelled in certain ways, and even put on pallets in a certain fashion. I guarantee if Walmart WANTED, the breeders would ship the fish however Walmart specified, because its freaking Walmart, and if one company/breeder won't do it their way, dozens of others will. So, while the breeders may be responsible for how they are shipped, I guarantee it's because Walmart specified that is how they wanted them shipped.
