Known in the Far East as Swallowtails, Comets are perhaps the second most popular of all the Goldfish varieties. Comets were probably first produced in USA, and although very similar to the common Goldfish, do have some distinctive differences according to the breed standard, most noticeable, their longer flowing fins.
Again I am grateful to the acknowledged experts of the Bristol Aquarists Society for the definitive breed standard.
A wider colour variation is also acceptable, metallic (self-coloured or variegated in a pleasing pattern and similar on each side) or calico. Metallic colours should appear as burnished metal, extending into the fins. Calico fish should have a blue background with patches of violet, red, orange, yellow and brown, spotted with black.
