I work at WalMart, and mine has just started selling Bettas!! I am not too happy about this in the least! They have little 'care cards' next to where they are set up, and they suggest a large bowl. It states nothing about a heater, or filtration. I sent my Store Manager an e-mail on the work computer, letting know how strongly I feel about this, and asking if I could ((on my own)) print out pages to put near them about proper care for Bettas. And the misconceptions about small bowls, and so-on. What I am asking you for, the best sites that I could put on the flyers I make for them. There are a lot of websites that go along with the small bowl/Betta in a vase ideas, and I want to bring people away from that!
