Hi Nasa,

Water forms layers when it is cold. The bottom of the pond can be several
degrees warmer than the top. Someone here once measured the temps with a
thermometer.

The still water is also easier on the fish, they don't have to work against a
current.

I'd go with the 55 degree temperature to stop feeding. That way you won't be
caught by a sudden down turn of the temps.

My albino channel catfish is a good thermometer where feeding is concerned. He
simply will not eat if the water temperature drops below 52 degrees F, although
the gold fish and Koi will nibble if given a little food. So when my catfish
stops eating, I stop feeding them all, or at least only feed them when the
temperature gets above 52 degrees F. And even then, I only give them a small
amount that they can eat in a couple of minutes, and only a couple of times per
week, if the temperature allows, and only if they are interested.
