I've never had a Betta fish, but I see them often.  They're the small, colorful, ray-finned fish in pet stores.  Have you ever had one?
I have had all kinds of them, I have 3 kids, pretty sure they have all had at least a few
Nice.  Do you usually get them from a pet store or a pet shop or somewhere else?
Yes the pet store or sometimes Walmart would sell them
Oh yeah, I forgot Walmart can have some animals.  I'm not a huge fan of Walmart, though I do like Sam's Club sometimes.
Our local Walmart does not sell small animals anymore, but they did when my kids were young
I can understand them stopping selling them, with all the criticism Walmart faces against their policies and practices, they probably cut back on a lot of things people didn't buy much.
Walmart is not the best place for small animals, they need to be in a pet store where  they can be cared for properly
