I work at walmart so I can tell you that buying all of them definitely will not help the situation at all. They will just see it as sales and order more. I try to take care of all the fish (especially the bettas!!) but I can't always do it everyday sadly. I do my best to educate people on their proper care. Some listen and some don't. Still irks me when people ask what kind of fish can live in a bowl or those tiny tanks we sell. i pitch the 10 gallon kits all the time,as that's the biggest we carry. That doesn't always work either heh.
I actually get to order the fish for my store now,so I make sure the tanks don't get overcrowded as best I can. I would love to not order any bettas but customers will and do come in asking for them when they aren't there so higher management frowns on not ordering any at all. I will admit to buying a few from there myself that spoke to me heh. They are my weakness.........
