Goldfish Varieties - A Complete Guide to Goldfish Descriptions

Selective breeding over centuries has produced several color variations, some of them far removed from the "golden" color of the originally domesticated fish. Goldfish may also lose their "golden" color, or rather any goldfish color, by varying the spectrum of light under which they are kept, thus causing the scales to gradually change color (e.g., black to orange). There are also different body shapes, fin and eye configurations. Some extreme versions of the goldfish need to be kept in an aquarium — they are much less hardy than varieties closer to the "natural" original. However, some variations are hardier, such as the Shubunkin.
