Definition of goldfish. : a small usually golden-orange Asian cyprinid fish (Carassius auratus) often kept as an aquarium and pond fish.
First, goldfish are exothermic, as are all fish. Their body temperature is determined largely by the temperature of the surrounding water. They absorb energy from the water (and to a far lesser extent, from sunlight) and they release energy back into the water.oldfish in aquariums kept at 75 degrees will probably eat five to 10 times more fish food per month than goldfish kept at 58 degrees. Second, temperature directly affects other physical and chemical properties of water, which in turn affect the fish. Warmer waters hold lower concentrations of oxygen.
