Thanks for your reply. What has me stymied is that this is not one of my known fish. It's much smaller although not a baby. I spend way too much time observing the pond lol & have never seen this fish before. I guess as Bill Cody said it must have been hatched in the pond & somehow I didn't see it. Now I'm wondering if there are more strangers in there. Not sure how much my son spent having the pond built for me as a Mother's Day present but it's provided so much enjoyment I know it was money well spent. smile
