Another thread got a bit sidetracked with fish, and I thought it deserved it's own thread (easier to find things later) although, as always, feel free to stray off topic - not trying to be a thread cop.
I have a very small pond, one of those formed plastic ones. It has 3 plant benches around a lower base. I had 9 goldfish, down to 5. Usually when it freezes, I take the axe to the ice to give the fish some oxygen. I totally forgot to do this over Thanksgiving and was happy to see all the fish survived without my ministrations. I'm fairly certain the pond froze through, although maybe the bottom layer of muck didn't freeze solid. It's not very deep, maybe 2 feet in the center. What precautions do you take for your fish over winter?
I don't feed them very often even in summer, and quit feeding them about October. Sometimes they look interested and I'll toss hem a few flakes, but they don't do more than peck at it.
I also don't have a working pump anymore. The one I had been babying along has finally given up the ghost. So my water this winter will be still.
I just buy feeder fish at about a quarter apiece, so if I have to start fresh in the spring, no big deal. This particular batch has been with me I think 3 years so they are good sized. I even have one little dark baby that I see flitting around now and again.
