Comet Goldfish | Comet-tailed Goldfish

The Comet Goldfish is much like the common goldfish, but is a more reddish orange color and has a much longer, deeper forked tail fin! The comet or comet-tailed goldfish is a single-tailed goldfish bred in the United States. The fish is similar to the common goldfish, except slightly smaller and slimmer, and is mainly distinguished by its long deeply forked tail. It is the most graceful of the elongated goldfish, emphasized by their long tail.

This fish was the first variety of the single-tail goldfish to be developed with a long caudal (tail) fin and the comet-tailed goldfish breed was developed in the United States from the common goldfish by Hugo Mulertt, a government worker, in the 1880s. The first comet goldfish was first seen in the ponds of the U.S. Government Fish Commission in Washington, D.C.

These fish can be quite personable and are delightful to watch. One of the hardiest of the gold fish varieties, the Comet Goldfish are recommended for beginners. They are an easy fish to keep as they are not picky and will readily eat what is offered.

The Comet Goldfish is an elongated, flat-bodied variety of goldfish. The head is wide but short and it has a smoothly tapering body shape, from its back and belly to the base of its caudal fin (tail fin). The caudal fin is long, deeply forked and generally stands fully erect. 

The Comet Goldfish is primarily a reddish orange color, but they are also available in yellow, orange, white, and red.  Comets with yellow, orange, red, white, and red-and-white coloration are common. The red coloration mainly appears on the tailfin and dorsal fin, but can also appear on the pelvic fin.

Since they are omnivorous, the Comet Goldfish will generally eat all kinds of fresh, frozen, and flake foods. To keep a good balance gives them a high quality flake food everyday.
