What I would like to see is a 'Million Betta March' - photos from ALL the Walmarts across the USA, all the dead/dying/diseased/ disgustingly kept fish collected en masse on a website and the link to that mailed to a TV news department or six. And PETA. And the RSPCA.
Because that company is evil. To me, that level of uncaring for living things is evil. And I am not religiously inclined.
