That so interesting to hear some Wal-Marts don't sell bettas! I have two in my town (which is not big at all) and they both are always stock full of bettas.
So... I can't believe I did this. I got the ok for my fiancÚ, went back to the store, he was still there and didn't get him!!! He looked completely health in his cup (the water had actually been changed and he was well feed) and I started thinking of my bettas at home.
I am setting up all new tanks for everyone and I just felt like I would ignore all of them if I got another one. Fish are more expensive than I every imagined! I still have a back up tank ready though....just in case :)
