Apparently the combination of anti-predator netting and a load of ice sank the heater, which shorted out. We are hoping that it did no harm to the fish, but we have no way of knowing until the weather warms and the fish should venture into view. I did some scurrying about and replaced the heater with a new one, of better design, and this one is now in service, but as aforesaid—no way of knowing if everybody is all right. There is a gfi on the circuit, but I don’t know if that will have been enough.

The temperatures are in the minuses at night; the whole house was 55 degrees this morning.

It’s hard to get warm. But we don’t heat the house much in the winter: we don’t like heat. We’d prefer just a wee bit more warm, but that’s the way it is.
