Keeping bettas is actually a good thing unless if you do buy them and keep them in the cup they give you, a bowl, or even a vase. People who know about aquarium keeping though don't do this and they give the betta a better home. Basically, PETA is contradicting themselves. They want animals to be cared for like humans but to leave them in a cup at a store for them to live a miserable life until their death, PETA might as well be advocating people to wipe out the species altogether. If PETA were in control of the world, house dogs would live in the woods to be eaten by the wolves, house cats would live in the jungle to be eaten by the tigers, and bettas would live in the ocean to either be eaten by whatever got to it first or die by the salt content.
