Nope, tried to look last night with a flashlight, Colleen, but they are all hiding. I'm somewhat worried about them anyhow. Been reading others talking about "sleeping sickness" with fish, where they lay on their sides, look dead, until you disturb them. That's what several of my goldfish were doing right when it got the first cold snap. They seemed fine after that, when the water warmed with milder temps again, so now I wonder how they are fairing with the much colder air we had 2 weeks ago! I have 3/4 of the koi pond is totally open, and heater is off on that, too, but it never got a drift of snow on it. I've not seen any of the koi since pond froze, not even this morning, so they are all hiding in the "garages" and snuggled in other places as well, I guess. So, to me, the snow didn't do any good keeping the water warm, it made it colder. But, stream is now running again in the goldfish pond, so that will circulate warmer air to the water, until we get cold again tomorrow. Geesh ... then warmer again. It was in the 50's yesterday. I turned the heater back on in the goldfish pond, it's hanging right in front of the skimmer. It's in a wire basket, so can't melt anything if it touches. It's for a rubber bucket/tub, so it's safe for in my pond. Will try to circulate that warmer water and try to melt off more of the snow. At least the air temps were warmer the last few days. Going below freezing again tomorrow, but then back up to 40's on the weekend, I believe.
