Yesterday when I was at the store picking out my new Betta I was looking at other tanks. I already had one cycling at home for the new fish, but I was just curious. I found the "Betta section" and the tanks were so disgustingly small. Four inch cubes were the biggest "tanks" they had for the fish. It's even smaller than the little cup it came in and this was at a mom and pop pet store. Why do people think it's okay to keep a fish in such living conditions? I have a one gallon tank as my isolation tank, but other than that the rest of my tanks are three gallons. Now, I have two fish, both were bought yesterday to go into my pretty tanks, and they are my first two fish ever, but I just found that horrifying. I wish people did more research before buying pets.
