They are native to my area and should not be too hard to collect a few.

Any one know if they might be minnow eaters?

with the body shape they have it sure seems they would be. The are shaped like a miniature YP. My thoughts are if I can get a small breeding population they will feed on the gams in shallows and sheltered areas to help reduce the numbers of them. I should not have to worry about the PP numbers getting out of control because at max size they will make for a nice meal for many of the predators in the pond.

Goofing off is a slang term for engaging in recreation or an idle pastime while obligations of work or society are neglected........... Wikipedia
