COLDWATER FISH

'Coldwater fish', in the context of aquariums, refers to fish species that prefer cooler water temperatures than tropical fish, typically below 20 °C (70 °F). Some examples are koi and goldfish. These species tend to grow more slowly, live longer than fish that live in warmer waters and are generally felt to be easier to keep.
Japanese koi carps are coldwater fishes.

Goldfish are also coldwater fishes.
