Additional information:
The Comet goldfish is a hardy and adaptable fish that do not require too much care. It is actually one of the easiest fish to keep which makes it an excellent choice for beginners.
In the wild, goldfish are native of Asia where they became popular during the Tang Dynasty (618 – 907). At this time it was popular to keep carp in ponds. Some of these carp displayed yellowish orange colour rather than silver coloration. So they began to breed the yellowish orange variety instead of the silver variety and created what we call today the Common goldfish. The Comet goldfish has been developed in United States from common goldfish in the early 1880s.
They are a lot like the common goldfish in appearance but the fins are longer. The tail is deeply forked and can be almost as long as the body. The tips of the tail can be clear, which makes the Comet goldfish a really attractive specimen. They come in a variety of colors including yellow, silver, as well as a combination of the two colors.
Today, a few variants of the Comet goldfish can be found:
Sarasa comets are characterized by their red-and-white coloration and resemble the Kohaku color pattern in koi.
The Tancho single-tail is similar to the comet but it has a silver-colored body and finnage with a red patch on the head.
The Comet goldfish is a coldwater fish so the tank does not have to be heated. It will do well with a water temperature of 65° – 78°F, a pH between 6.0 and 8.0 and a dH of 5 -19.
