Freshwater Fishes of the World

We are busy “beefing up” the goldfish section at animal-world so I thought Id post some of the results. Comets are probably one of the most popular tropical fish types, especially for ponds. For a long time I wondered if there was actually any difference between a comet and a common goldfish. As it turns out… there is a difference which is apparent once you know what to look for!

Comet 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 Goldfish, also called the Comet-tail Goldfish, are a ‘reddish orange’ colored goldfish that are inexpensive and readily available. This fish was the first variety of the single-tail goldfish to be developed with a long caudal (tail) fin. It was developed in the United States from the Common Goldfish in the early 19th century, presumably by Hugo Mullert of Philadelphia who then introduced them in quantity into the market. Though they are a bit smaller goldfish than the Common Goldfish, they are every bit as durable and can be kept in either an aquarium or in an outdoor pond.
