I have 9 bettas and 2 of them I got at walmart, 1 at a pet store at the mall and the rest at Petco. All of them are doing great and are little sharks when it's feeding time. :) I just got the 9th one today from walmart and he was in disgustinly cloudy water and the water was maybe an inch and a half so he didn't have much room to swim. He lookes so sad, so I saved him and now he's very happy! I have all males because they're colors are just magnificent. But like Ilovemyshiny
said, just go to a pet store and see which fish draws your eye.
