Quick question. I have prepped our pond for the winter. I've got the waterfall running 24/7 with the skimmer doing it's job. Winter has definitely been hanging around for about a month. However, here in Oklahoma, the temps have been all over the place. As low as 20F and as high as 68F over the last month. I stopped feeding the goldfish when the first really cold spell came through and they disappeared for about a week. Then as things warmed up slightly, I have seen them out and about. So my question is, should I be feeding them if we have several days above 50F (but nights are in the 30's)? Thanks in advance!!
