Yes actually they will

Ok worst case scenario a 3$ pail of minnows might take twice as long to do the same job.
I'd go with hanging them off the dock in a pond myself. Bluegills and other small fish come quick if you don't move.
Sitting on the dock taking in some rays 0$
Having small fish nibble the dead skin off your toes 0$
Getting back in touch with yourself and nature, Priceless.
