I went to walmart to get a fish, a betta fish actually, and they were all out so I was just going to get a goldfish instead and put it in a fish bowl but the lady was like "Oh, it won't survive in a fish bowl it has to be in a tank." But, the fish was full grown and it was just as big as a betta maybe a bit smaller and she said it was too big. I was really mad. So, can a goldfish survive in a fish bowl that is like a 2 to 3 gallon ish bowl... I think.
