OMG, is that a Black Moor you have Colleen? That is one that I thought would never survive the winters, as they are more "deformed" than the others. I also have fantails, Keith, and this being only my second year, the ones I had from last year made it just fine. I bought several more from Wal-Mart, and most of them survived, I think I have about 6 or 8 of them going into the winter. I did see one belly up on the bottom couple of days ago, so assume that one died for whatever reason. The ones I got from Wal-Mart were small, maybe only about an inch long plus their tails, so I expected some of them not to make it. But most did make it. And, I have only seen it once, but I put a copper colored fantail in the pond, didn't see it until I was in the pond grooming the lilies, and saw a solid black fantail! I guess that sucker changed to black, from bronze/copper color! I hope it's still in there, but won't know until spring. I always watched for him/her, but never saw it again. So many places to hide, though, I will be hopeful that it makes it! Could have changed to solid orange, but didn't have any solid orange ones either.
My pond has more ice on it than yours, Keith! I have the waterfall, stream and skimmers going, thanks to Colleen! If I wasn't going to be gone, I would keep them going, but unless the weather prediction for the 11 days I'll be gone doesn't call for below 25 for nighttime temps, I'll probably be forced to shut down the waterfall. Going to leave the stream and skimmers going, though. Have water bubbler on goldfish pond in front of that skimmer, and air bubbler on the koi pond in front of the skimmer there. I think that should keep the ice from forming in front of the skimmers, since they are pulling in water and moving it so should not freeze. The only thing I worry about (also worries about tubing above ground ...) is if the flexible sump pump tubing I've used would break, that would empty my pond down to about 14", which I don't want to happen, especially if I'm gone! So, we shall see ... I'm sure enjoying having no ice on the ponds, though!
Another thing I've noticed is that the goldfish pond, which has stream, has had almost no ice, but the koi pond which has the waterfall (more above ground) has ice on it. I would conclude that the water running over the stream which is on the ground level is warmed by that, and the water going over the waterfall is more cooled, thus colder water and more ice on the koi pond. But, always open areas where the water is moving, even from the bogs!
