Do not feed goldfish because it turns the pond into an outdoor aquarium, but here's yet another reason not to feed them.
Fish soon realize that when a shape appears at the edge of the pond, food appears. They like that and soon they are trained to eat out of your hand. At least that is what you think.
Fish are not the brightest of critters, so when ANY shape appears at the edge of your pond, like a heron, an egret, a crane or a raccoon, they come up to greet the intruder and oops, they become a fresh sushi dinner for a hungry intruder.
