Pond Comets (Carassius auratus) are a member of the goldfish family. They have orange scales with a long, slender body. Differing from the regular common goldfish which have shorter rounded tails, pond comets have a distinct "V" shape to their tail, allowing their tail to be very long and flowing. They range in size from 1.5" to as large as 14".
Comets are primarily solid orange in color but do have other variations. You can occasionally find some with black markings, or some that are solid white or solid black. However, the most popular variation is the sarasa comet which is mainly white with red markings.
Like all other goldfish, comets are hatched from an egg and are smaller than an eyelash in the first days of life. Amazingly, by 45 days they will grow to a marketable size of 1.5" - 2.5" but will need additional time for their color to develop.
Comets are a community goldfish and will do great in any freshwater aquarium setting with all other goldfish. Also, comets are very active and are suitable for outdoor ponds with koi and butterfly koi.
