Coldwater fish

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 (68 °F). Some examples are koi and goldfish. These species tend to grow more slowly and live longer than fish that live in warmer waters, and are generally felt to be easier to keep.

Japanese koi carps are coldwater fishes.

Coldwater fish are fish such as goldfish, koi, and other members of the carp family that are able to survive in cold water temperatures. When kept in a household aquarium, they do not require a heater and are quite comfortable at around 60℉. These fish are also desirable choices for outdoor ponds, although they must be kept indoors during the winter.
