It came from my freshwater pond in central Indiana (about 1.3 acres). I thought it might be a golden shiner since I added 60 minnow-sized shinners from a bait shop a couple months ago. I know this is a bit risky, but I looked at each fish to see if they all looked the same. Is it possible for golden shiners to grow from 3" bait fish into this sized fish in less than two months? This seems like increadible growth! I have never seen a fish like this in the pond before, and I caught two of these in a minnow trap where the pipe leaves the pond yesterday. I added these along with 10 lbs of FHM this spring after a fish kill. I have since seen surviving LMB and BG, so I thought that I had bought expensive fish food.
