I culture my own red wiggler worms (also known as composting worms). Super easy and a single rubbermaid in my garage supports feeding a 50+ tank fishroom a couple of times per week.
Haven't bought live or frozen foods in years and have yet to find a fish that doesn't want to eat them...

Matt, have you kept pickerel? I do really want mine to take worms, and I have tried on several occassions, they dont even bat an eye at them. crickets, prepped foods, they will zone in on, but worms they don't even give the time of day. My current pickerel, speedy, will target anything in the water (taking it, different story) but he just wont even look at worms.
