My first fish was also a goldfish from the fair, though not a won one, when I was young the fair near us was not very nice, when they went to move they threw their goldfish down rabbit holes (I heard it was cheaper to buy new ones than transport them) so one year I went armed with a bag filled with water and found a couple still alive, they lived for years; they are dead now (due to a fishing cat of mine) but when they died they weren't around to eat their own eggs so we got the next generation of goldfish, their kin are still in my parents pond.
