Comet Goldfish
Among the different types of goldfish, the Comet goldfish is one of the most common. The Comet goldfish is slightly similar in size and appearance to the common goldfish. However, the Comet goldfish’s body is more slender, and a bit smaller than the common goldfish. The most distinguishing characteristic of the Comet goldfish is its long, flowing, forked tail. Comet goldfish have the ability to grow their tales to over 12 inches in length! However, this is usually only possible under optimum aquarium conditions. Due to the length of their tail, Comet goldfish are susceptible to fungal and bacterial infections, such as fin rot. Comet goldfish do have a dorsal fin, which extends from roughly halfway down their body to the beginning of their tail.
Comet Goldfish can be many colors, including white, orange, red, yellow and a red-and-white pattern. These colors may be either enhanced or dulled by the fish’s stress level, diet and tank conditions. Comet goldfish are relatively energetic, more so than many other types of goldfish. They like to “play”, and are often seen darting back and forth in their tank. They are also very hardy, being able to adapt to small variants in temperature and water quality. In most cases, a Comet goldfish will live from 7 to 14 years, though it is possible for them to live longer with proper care. Comet fish may be kept outdoors, and are sometimes kept with other outdoor fish, such as koi fish. Comet fish are relatively easy to care for.
