A couple weeks ago I went to a neighboring town public park for a walk. There is a large pond in middle of the park with a large amount of very large Koi fish, the fish were on an average larger than 2 feet some of them were in my opinion almost 3 feet in length with buetiful colors and markings. There was a man sitting on the bank of the pond with a loaf of white bread feeding these Koi fish and the fish were in a feeding frenzy, I never seen anything like that, there must have been over a 100 large Koi going crazy eating the bread and a feaw ducks tring to steal some of the bread from the fish. My question is, is it safe to feed Koi human food like bread with out harming the fish. It seemed those Koi loved it.
