I just wanted to tell you all that not all walmarts are the same, because the one near me is kinda okay. I mean they do put the bettas in little cups, and they dont have that much water in them. But I just wanted to say that I have bought 4 bettas there and none of them have died, gotten sick with anything, and they are all perfectly fine, except they had a few nipped fins!
The reason I go to Walmart is because the only other place i know where I can buy fish is like an hour away, and I dont have time to go there that often, and my mom doesnt like me to drive there. HEHEHEhehehehe but I do anyway.
