While the fish are happier in the pond I have a feeling it's a little cold for them. The waterbed heater I tossed in doesn't crank out lots of heat (it takes days to heat a cold bed, and that is indoors and covered). Yesterday Faith went to check out the fish and was stunned to find that all but two were gone. Predators? Racoons? Smudge? Nope. Waterbed. The fish have taken to hanging out inside the curled up heater. Yum, self cooking fish!
