I got 17 cent feeder fish from Petsmart. 4 at first, then 2 more. I bought two sarassas (spelling?) from a pond store and ended up adopting 6 from a friend's pond. There have been some in-pond-parties and now have a bunch of fish kids! I have counted a total of 22 all together. The first resident fish are all around the same size now but one of the sarassas is the heartiest. I call her Pig and she lives up to her name.
