The Comet Goldfish, also known as the Comet-tailed Goldfish, is the only breed of goldfish that was developed in America. They were developed by a gentleman in the 1880’s and were first seen in Washington D.C.
First bred and introduced into the commercial aquarium market in the late 1800s, the Comet gets its name due to its long, flowing tail fins. Many people think these give the fish the appearance of a comet burning a trail through the sky. They will dart around their enclosure and due to their hardy nature are best suited for a pond.
Comets are very similar to Common goldfish and the two are often confused.
Some differences are that the Comet has a longer body and longer, flowing fins.They are more slender and their fins are more noticeable and elongated. Their caudal fin is more pointed than the Common Goldfish and their tail is long and deeply forked. Their caudal fin is usually seen as more than half the size of their body. They have two pectoral and pelvic fins and a single dorsal, anal, and caudal fin.
Comets are usually reddish-orange in color. However, they also come in red, orange, yellow, white and bi-color varieties. The Sarasa Comet is a red and white bi-color variety.
Temperament and care
The Comet requires no exceptional care and can survive in the same conditions as Common goldfish. Comets are a very hardy variety of goldfish and therefore an excellent choice for beginners. They come in a variety of colors that make them look great in a pond and since they are quick and playful by nature this is the type of habitat that is usually best for them.
Due to their hardy nature, Comets make excellent pond fish and are usually a feature of koi ponds. Comets should not be kept with slower, double tailed varieties. This is largely because they are strong swimmers that are able to out-compete their slower cousins for food.
Feeding Comets is quite easy, as they will eat almost anything they can fit in their mouths.
Comets, like all goldfish are omnivores and can be fed regularly on a diet of flakes or pellets available at pet stores, plus vegetables. For instance, you may want to feed them pieces of cucumber, zucchini, broccoli and shelled peas.

Choosing comet goldfish
In order to pick out a good fish, it’s important to know what desirable features to look out for.
For instance, all fins of a comet goldfish should be single except the pectoral and pelvic fins.
The tail fin should be long and ideally more than ¾ of the length of the body.
Finally, all of the Comet’s fins should be pointed and erect without any folds or any overlapping.
