That walmart sounds pretty bad, My walmart I work for is alot better with their fish tho, there is still problems like no hiding places for the fish and some tanks do have quite a bit of algae, the fish are still pretty healthy tho and if I can I try to buy em from there to at least save em from the stupid people and the tanks there. Tho I wont go out of my way for em If I don't want/like the fish I wont get it
Ive stopped buying from them hoping they will eventually get the picture and stop selling fish that are practically dead already. If i was to buy the fish cause i feel bad the store will see this as just sales and order more
