BC, calm down...lol, funny reading. Many here have seen much worse, ever seen a pond go dry and watch your fish die ? Also, you're not positive that your "bad" fish came from a fish farm, read up...many here have been on the "wrong" end of a neighbor who just wanted to help. Your pond is young and can easily be corrected, just chalk this one up to experience. Get out your fishing pole...toss what you don't like over your shoulder. Even with the best pro's managing your pond, you still need to catch and release...catch and toss...or catch and cook. With a good effort, you can turn your fish balance over in a hurry. Read here first, then find out where you screw up, read again...all of it is here ! You just have to go through the trial and error phase of it. Very few have done "everything" right the first time.
