If ever in my life I had seen a turtle with 1/2" of moss on it's back I would not have made that comment. I have many turtles and their backs are as clean as can be. Possibly the cold water and wintering under the ice prevents it. My water just recently passed 70 degrees. It's amazing how opinions can vary between people that are 1500 miles apart.
I also agree on the green sunfish. One of the biggest reasons people avoid the hybrid bluegills here is that they can revert to green sunfish and the bass don't prefer them to the abundant forage here. Of course we never stock native bluegills in Wisconsin because the bass don't even come close to controlling their numbers here. My bass have just started to feed heavily in the last week or so, just in time to control any baby cats. The clouds of them appeared in late july last year and this year the water is colder.
