Mark -
Your fish are beautiful. I really love the shishui's and yours' have quite a bit of blue on them. When I bought mine, I chose the one that had the most blue and he has kept most of his blue. How long have you had your pond?
Occasionally I see Mr. Heron flying overhead. I live between 2 rivers and it was a number of years ago that he visited us. We put in one of the sensor sprayers that really worked as a deterrent, but my sprayer died this past Summer. Mr. Heron has not discovered that he could probably snack on my fish, but I am afraid that he will figure that out soon..... I do have the straight sides on my pond, too and I think that helps.
