You wish! No, unfortunately, I counted 8 tanks sharing the same water at my local Wal-Mart, and then 4 sets of those. 32 total tanks, only 4 water systems. Watch one tank get ich, and all 8 are infected.

I feel bad for the fish at Wal-Mart, but am too scared to try and rescue one for fear of contaminating my tanks with something. If you were going to buy a fish at Wal-Mart, you would have to carefully study every fish in all tanks connected to the same water system...a lot of hassle just to save a dollar.
