Wow, I don't think I'll ever get a betta from Walmart after these stories.
My Petco near me actually often has a lot of variety of bettas .. they have veiltails, doubletails, crowntails, deltas, halfmoons, halfmoon doubletails, plakats, "Kings" (is that the same as Giant?), females, males, and babies. All the time. And I have seen some crappy looking ones but also a lot of really interesting looking colors and some that look pretty lively. I have 3 from there and they are all doing very well.
BTW ShadowCourtGirl, sorry about your dead fishy and Congratulations on your consolation fishy - it is very very pretty. :)
