Terry, If this was my hobby and I didn't care what it cost, I would go for hatchery fish. That way I would know that I wasn't introducing any small trash fish or any diseases. To do it right would probably cost an estimated $500 for good stockers. That is less than rotenoning to get rid of problems and start over. Before I did anything I would test PH and alkilinity of the water. While this stuff ain't rocket science, it is pretty easy to make stupid mistakes. I've got a Ph.D inscrewing up because of taking shortcuts.
