I have seen it
So I went to Walmart a couple days ago... Went to the bettas and found a male and a female in the same cup. The same cup. And right above it was a empty cup. There was a walmart employee right there and I showed her this. She said, "That's how they come. I just scoop them out." She probably thought she knew more because I am very young. And then I saw a betta cup on the top shelf. There was a betta, dead and rotting, in it. THE WATER LOOKED LIKE APPLE JUICE. I pouinted this out to the employee. "That's not my job hun." And she walked off.
