It's sad but true wal-mart rarely does anything in their fish department here. The rocks were literally covered in black algae, there is never anyone around. I went in one day and there were 3 people in there working on the tanks, and I was like "great finally someones going to do something and take care of these poor fish" well guess what the black algea's back and the fish are dying left and right and living in HORRID conditions. They clean the tanks rarely, most of the time they don't even know what fish they have. My guess would be that they just throw the fish in there and feed them "maybe" once a day if they are lucky. If they are lucky enough to be bought by someone they probably get put in a tank or a bowl that is WAY too small. It's appalling and disgusting.
When I lived in NH the wal-mart there carried fish. Some kid poured dog shampoo in their tanks and wiped out all their fish and they completely took the fish section out. I thought it was awful at first but now I think about all the fish he probably saved.
It broke my heart.
