JohnK, as Dave Davidson said, Tilapia are not a magic bullet, they are the closest thing to it for ponds though...It is all about your goals for your pond. The most used phrase on this forum is it all depends. It is also the most accurate phrase. I invite you to follow the link in my signature to an ebay listing. I have a rather long winded synopsis that is wriiten to be easily understood and provides a great deal of information as to what tilapia can do and why.

Every pond and every pond owner is different. Tilapia may be a perfect fit for you, they may not.
