What about feeding in the colder weather?
	When the pond temperature gets down to 50 degrees you should stop feeding them. By this, I mean only feed them once or twice a week instead of two or three times a day. Also it is a good idea to feed them wheat germ or other low protein food. They will still come to the side and look at you with those hopeful eyes but it is dangerous to feed them the same when the temp is so low. The food just sits there inside them and rots as their metabolism cannot handle food at low temps.
