You can actually feed snappers dead fish until you get your minnows out of there. They will scavenge and get a free meal vs. chasing minnows. I've seen them make the rounds on drainage grates before. And we use to catch them with big chunks of meat, mostly common carp. Go catch a common carp, slice it into chunks and put what you don't use in the freezer. Soon the turtle will be like a pet, almost eat out of your hand, maybe your hand also if you are reckless. At least a finger or two.
