i just have one question for every one who is just complaining about walmart.
have any of you schedualed an appointment with the manager to talk about volunteering your time to go down and personally change and maintain thier bettas?
i would just about guarentee that if you used the words "volunteer" and "more profit / money" in the same sentance they would be aminable to it. already most of yu are buying your bettas in those cups any way so you are supporting the system you are complaining about. might as well keep the cups clean and feed as proper as you could so that your next purchase will be better than your last.
just explain that bettas are living creatures and will get sick and look sick faster and thus sell less and have to be cared for longer than healthy well maintained animals. if that doesn't work get some local betta enthusiasts to send mass letters to said manager with a letter writing campain to improve his bettas. just remeber to them it is all money so no matter how much you bug them you need to make a case for the bottom line. either in better faster sales or in less die offs.
if all else fails you and all betta lovers in your area just stop shopping at that walmart.
