Catch the GC on a Stubby Steves or make an imitation pellet. They learn fast.

I had a bunch of turtles eating the pellets in my pond. I have no idea where they came from, but I reduced their numbers with a .177 pellet gun. That was a few years ago and I think the rest got the hint. There are only one or two in the pond now.
