Definition of goldfish. : a small usually golden-orange Asian cyprinid fish (Carassius auratus) often kept as an aquarium and pond fish.
Goldfish are exothermic, like all fish. Their body temperature is determined by the temperature of the water. This means that goldfish are at the mercy of the water temperature to regulate critical body functions. Simple functions such as locomotion are affected by water temperature. Goldfish in cool ponds move more slowly than goldfish in very warm ponds.
