Almost all the Walmart's here in the chicago area sell fish and it disgusts me. Petco's are no better as neither store knows how to properly care for for fish. We have a local petco that has over 35 little Betta cups and they all just sit at the bottom and exist until death free's them. The Walmart near my home goes through guppies & cory's like skittles and not from sales. I don't think any store should be able to stock/sell fish without having properly trained people to take care of them, but we as humans tend to think that all other forms of life other than ours is insignificant and if a fish dies oh well it's just a fish. Sounds like a rant or is one but better training would definately make the hobby much better.
