I have gotten most of my fish at walmart. A couple have died, most are doing fine. I really like the associate that works in the dept. he is a hobbiest as well. My walmart has strip thermometers on the fronts of the tank and they all say like 80 degrees or around there. He tells me they don't work and they have floaters they pay attention to. He keeps the tanks pretty well taken care of. I think most of Walmarts problems are the sheer mass of the fish they have in their tanks. I DO NOT put their water in my tank. I float them for about 10 mins and then dump half the bag in the sink fill back up with my water from tank and let sit another 4 or 5 mins and then I use the net to get them out although petland says to let them swim out Of course they also tell you to put their water in your tank, so I just use my judgement. Also, about Walmart, it isn't the fish you are looking to buy, of course they are healthy or you wouldn't be looking at them, it is the fish in the tanks with them!! Look all around the air hoses too, I see so many dead fish there.
