New Fish and tank investment

How about just getting a few goldfish and guppies. We had a smaller tank when I was a child and had the these fish and later got two angel fish. Those are easy to mantain in a smaller tank, and once you get the knack of having them you could get a bigger tank or better yet move closer to a public aquarium where you enjoy the fish and someone else maintains the tank and the cost in it's upkeep. lol
