The aquarium is the best place for Goldfish because it is properly safe for Goldfish. You know fishes live in rivers which are too big and open. The aquarium is not a river but it has too much space where Goldfish easily swim and play. There you can keep too many things that your Goldfish feel like a river whereas, the bowl has not too much space for swimming and not great protection at home. Like suddenly fishbowl throw down and Goldfish die in some time and the children can catch the Goldfish easily in a fishbowl.
