We got a goldfish from a carnival. We thought as you did. The fish would not live very long. We bought it a nice goldfish bowl etc. Well that was at least a month ago

This fish has grown a lot. Now, he is too big for his bowl. My husband and I just bought our three year old daughter an aquarium

You are right, usually carnival fish do not live for very long. However ours is still going strong. I am now learning how to take care of an aquarium, which is turning out to be harder than I thought.
