YOU GO GIRL!
I had to smile at your post. I would have done the same thing. In fact, at Christmas I jumped all over our local Walmart store because they were selling Beta fish in little cups with only about 1/2 cup of water. They couldn't even turn around. I was told that the fish were quite happy that way. I told them it was cruel. I noticed next time I was there, the fish were gone. I hope to homes with bigger tanks.
