It's good to hear that there is a Walmart out there with well-kept tanks, but I still would be wary. I haven't checked out the nearest Walmart to see if they even have a fish dept, but I don't have my hopes up for anything good. The Petco near me is terrible, though. I saw a tank with Flame Gouramis and Silver Dollars. The fins on every single Silver Dollar were torn to shreds and they looked extremely stressed. On top of all that there was a dead Gourami floating at the top of the tank. Just disgusting. I completely agree that fish care in stores should be held to the same standards as for kittens and puppies.
