Let's Stop Pet Stores From Selling Beta Fish

When Beta Fish are sold in pet stores, they're kept in little glass jars, a glass really. Sometimes they're sick or even dead already in these filthy jars. I don't understand how anyone thinks it's okay to cage a fish, or any animal, like this. It is so inhumane for a fish not to be able to swim. Animals should be able to do what comes naturally to them. Fish should be in an ocean, lake, river etc. NOT confined to a little glass.
