Types of Goldfish
Experts believe that the goldfish originated in China and are descendants or at least distant relatives of the carp. They have been bred in captivity for thousands of years and there are now several different types of goldfish available to purchase.
There are two main kinds of goldfish; single tailed and twin tailed. Single tailed goldfish are more similar to the carp in body shape and fin size. Twin tailed goldfish actually have two tails that are fused together at the base. The tail and fins tend to be a lot longer than the single tailed varieties.
Single-Tailed Goldfish
Common – As the name implies, these are the most common of the goldfish varieties. This is the fish that immediately comes to mind when someone mentions ‘goldfish’. They can actually be found in a multitude of colors including orange, red, blue, and brown. Unfortunately, these are used quite often as feeder fish for larger fish. Being coldwater fish, it is best if you do not place them in a tank with more exotic varieties of goldfish. Fancier fish require environments with warmer water temperatures.
Comet – This variety of goldfish is colored wither white or yellow and will have red along the back. Their tails are quite ling and they are extremely quick swimmers. Comets make perfect first pets as they are a resilient class of goldfish that can quickly adapt to changes.
Shubunkins – This type of goldfish is sometimes referred to as the calico goldfish on account of the variety of colors that are speckled over its body. Patterns of silver, blue, black, brown, and yellow adorn this colourful fish. Physically they are very similar to common goldfish. The only real difference is the color patterns.
Twin Tailed Goldfish
Lionhead – These unique looking fish have a head that is shaped much like a brain, which is called a wen. Their bodies are short and they do not possess a dorsal fin. Because they are slow swimmers, it is best if they are kept in a tank with other slow swimming fish. This makes it easier for them to compete for food. Faster fish would snatch up morsels before the Lionhead had a chance to even swim close.
Black Moor – This variety of twin tailed goldfish sports huge protruding eyes and a beautiful black coat. Moors are very slow swimmers, like the Lionhead, and they possess extremely poor vision.
Fantail – The Fantail is one of the oldest species of goldfish and also one of the most popular. It is available in a range of colors including the most common red and orange hues. Sporting an oval shaped body and long, trailing fins that make up about a third of its body length, this is a very beautiful and hardy breed of goldfish.
Veiltail – These elegant goldfish have extremely long and flowing tails and fins, hence the name. They are not considered to be agile swimmers so they should be kept in a tank only other similar goldfish. Take care not to adorn the tank with sharp ornaments or decorations as these can easily damage the thin, graceful tail. Veiltails also thrive in warmer water temperatures.
