How long do goldfish live?
How big can a goldfish get?
Goldfish can vary in size depending on the type of goldfish as well as their environment. Some goldfish have been known to grow up to 2 feet long and nearly 10 pounds. This is the rare goldfish, however. If you have yours in a fish bowl, don't expect it to get much bigger than a few inches long.
What do goldfish look like?
There are many types or breeds of goldfish. They can vary in size, color, and shape. Many are orange-gold in color, but some are grayish-white with orange spots (like the comet goldfish) and some have black spots or are olive-green. There are fancy goldfish, like the Jikin, which has a butterfly or peacock type tail. The Egg-fish goldfish has a more rounded shape, sort of like an egg. One type of goldfish, the bubble eye goldfish, has big bubbly looking eyes that bulge out from its head. Pretty cool!
A well kept goldfish in the perfect environment can live for years. There are instances where goldfish have lived over 40 years. This type of longevity is rare, though, and many aquarium goldfish will live for 6 to 8 years when properly cared for.
Where do goldfish live?
Goldfish are a freshwater fish and like to live in water that is 50F to 76F. Many goldfish live in aquariums and small domesticated ponds, but some do live in the wild. In the wild they live in slow moving rivers, lakes, and ponds. They like to eat plants and insects when living in the wild. When living in aquariums, they like a lot of space. At least 10 gallons of water for each fish, but the more space the better as this gives them more oxygen, which they get out of the water.
Where do goldfish come from?
Goldfish were originally from China. During the Tang Dynasty and the Song Dynasty the fish were bred for their golden colors. Later, goldfish became popular in Japan where many new breeds were introduced. They were brought to the United States in the late 1800s.
How smart are goldfish?
Goldfish might be a bit smarter than you think. Some goldfish can see and remember well enough to distinguish between people. They often notice the person that feeds them each day and will get excited when they see them. There have been cases where goldfish have been trained to do tricks like swim through mazes, swim through hoops, or even push a ball into a net.
