A good 200m time for a goldfish is about five minutes. This depends on the size of the bowl, however. A standard size bowl would involve too many laps and the fish would die from giddiness. A 3 gallon bowl would be a good idea, but you're still talking 200 laps. (10" diameter bowl = ~metre/lap at the widest point.)
Sorry, what was the question?
You are a goldfish, aren't you?
