I realized last night that the heaters weren't on ... uhm ... never plugged back in from the partial water change days ago! The water was down to 71F. What can I say. Fortunately the fish seem fine - I imagine it can get even colder than that in the wild, but then these are spoiled fish....constant temperature (usually), regular meals, clean water ...
