Now you mention it Snrub, that makes a lot of sense. I didn't think about the water playing tricks. Plus we've both been anxious to see them since we turned them loose. We have them where they don't seem to be real scared of us as long as we don't move around too much on the bank. They come up pretty shallow when we feed, but not close enough to get a real clear view. If either one of us could see better, it wouldn't be a problem to see them.
