Are you sure it's not a skim coat of dead alewife?
Hey merrit. Yw for emptying the tank. Did not catch anything on those sickle back minnows. I throw them on the ice to die. Did put a few bobber poles down withe the six good minnows I did have but only had one bite on them. My boy lost a pike or big bass. Did ccatch five pike on tip ups. Ice was a short three inches but softened up by mid afternoon last Friday. But the ice report is pretty null and void now after this deep freeze
Not with minnows
