Gold fish is a carp - this is a misnomer. Technically goldfish are not carp. Koi and carp are basically the same fish specie Cyprinus carpio. Goldfish are a different genus and specie technically Carassius auratus. One of the distinguishing differences between the two is that goldfish do not have the noticeable barbel at the corner of the mouth. The mouth barbel is loaded with taste buds and allows the carp to taste food when the snout is submerged in bottom mud thus the carp mainly roots or feeds in the bottom for food items. Plus goldfish do not have the protrusible mouth as do carp and koi. Goldfish when abundant can create turbid water as do carp by foraging in the sediments for food items. Individually goldfish do not get a big as carp and koi thus carp can create more muddy water per fish than a gold fish.
