I'm a little north of Tampa, and the same front hit us (first!). The water
temp dropped to 47.5*, then climbed "all the way back" to 51.6*, where it is
now. My fish did the same thing: they found the deepest spot and lined up,
rank and file, nose to tail and stayed put. They just don't like the cold,
that's all. When the water temp gets up a bit, they'll move around. Our
"Southern" koi just don't understand what their Northern brethren go
through, and they're a bit spoiled.

Happy Holidays!

I have a 1200 gallon pond in Miami Beach. I'm 1/2 block from the bay
and 3 blocks from the ocean with two canals in between. So one would
think that we're protected from much cold. Temps went into high 40's last
week for maybe two days. These lows were not long lived for these two
days as well. The sun still shines here, its only the breeze that gives
you
a chill.

The point:
Since this cold front our fish are all cowered in one corner together.
They
don't
seem to want to move more than 2'. Any ideas? I don't see any signs of
critters.
