some of us care greatly about our fish, and other fish. sadly, many don't, and think of them as throw-away pets because they never get to bond with an amazing goldfish, cichlid, betta, or other amazing fish.
if you have a facebook, the group "Fight Wal-Mart fish cruelty" works hard to stop things like this. just, keep contacting them, leave them nasty notes and e-mails when things look bad, and don't let up. the walmart near me actually stopped ordering bettas, and is re-doing the fish supply section, and has no place for new bettas!
