It all depends on what the "minnows" actually are.

This is when you get down and pray: Please don't be GSF, Please don't be GSF, Please don't be GSF.

Just kidding. Bobby is right though. We have GSF and didn't know it until we started trying to catch some of the BG and RES we stocked back in July. Now I worry that I might have lost my LMB and many of the BG and RES fingerlings. Guess we'll see in the spring. Why not dip up some of those and post some pics. The experts can tell you quick what they are.
