The American Shubunkin has long and forked tailfins
The Bristol Shubunkin has forked tailfins but it ended in lobes
The London Shubunkin has short and round tail fin.
Shubunkin can grow quite large size reaching length of almost 12 inches measured from head to tail and it is considered a hardy variety meaning that it can tolerate moderate changes in water parameters quite well. Because of its size and active nature (fast swimmers), Shubunkin are sometimes kept in ponds together with koi where they can grow and thrive better compared to keeping them in large glass aquariums.
As with all goldfish, Shubunkin readily accepts all types of food and a very hearty diet. Because they eat a lot, usually they will discharge a lot of waste and fouls the water easily. Shubunkins are recommended to be kept with other fast swimmers like the common goldfish with water temperature maintained at about 20 – 24deg Celsius.
