Fish near surface - OK??

after checking water ala Jan's suggestion, what is the temp? my koi head to the
bottom when the temp drops below 48o. with the 500 watt heater they been up at the
surface looking for food. the water temp has remained been between 50-55o and they
get a very small amount of food if they are up at the top and somebody grabs the
pellet when I throw it in. Ingrid

Help please!
Just noticed my fish are near the surface of the pond (12 foot by 8 x 2 fot
deep) - I have the pumprunning 24/7 and have a small waterfall for aeration.
The fish are not gasping - seem perfectly OK, but normally I'd expect them
to be at the bottom when it's cold (last night it was about 1C minimum.
There is not much debris in the pond (newly created this year) and the water
is quite clear.
Should I be concerned about the fish?
I've had fish for quite a few years (biggest are 12inches).
Thanks for any info.
