Species group: Goldfish
Other common names: Hibuna
Scientific name: Carassius auratus auratus
The Common Goldfish is very popular at fairs and often chosen as a beginner fish because of their ease of care ability to survive a wide variety of water conditions. The Common Goldfish is descended from the Prussian Carp (Carassius auratus gibelio), which was originally native to Siberia, and has now been introduced to lakes and slow-moving rivers throughout Asia and Europe.
One of the challenges to keeping goldfish is making sure they have a large enough tank as they grow. It is a myth that fish will only grow to the size of their environment. Goldfish live an average of 20 years but will die after 3 to 5 years if kept in too small of a tank.
Being such voracious eaters makes feeding goldfish easy. They will eat flakes, pellets, fresh fruits and veggies, and even graze on algae in the tank. When kept outside they will eat bug and mosquito larva too making them great for mosquito control.
The Common Goldfish has a smooth body and a forked tail (caudal fin). It is available in many colors, including red, black, orange, white, bronze and yellow. They can also change colors as they grow. Most Goldfish hatch bronze and become gold or white.
Common goldfish are peaceful and can be kept with koi and other cold water fish like comets, shubunkins, and snails. Because they are long bodied and can swim faster it's best not to keep them with round bodied goldfish like Ryunkins, and Orandas or they might steal all the food before the round bodied goldfish get any.
Common Goldfish, like most goldfish, are best kept in cold water aquariums.They need at least 100 gallons per fish once full grown. They do best in outdoor ponds. Good filtration is necessary because they produce a lot of waste and stir up the aquarium constantly.

Simple but wonderful
I love the heartiness of a simple goldfish. They are so easy to care but my only complaint is they are messy. I love how friendly they are and come to the surface to bed fed once they get to know you. Great starter fish. Even though they are cheap and some people treat them as disposable, get to know them and they will show you their worth..

It's not "just a goldfish"
I met Beethoven when he was staring in a show I was working on. Well, okay, he wasn’t really the star. He had hardly any lines, and was not on stage all that long. But, as far as Beethoven and his understudies were concerned, he was the star of the show. As you can see, he was prominently displayed on the poster. After the show was over, Beethoven needed a home. Thinking, “Oh, it’s just a goldfish,” I decided to bring him home. All I need is a bowl, right? Wrong. It turns out that goldfish actually need quite a lot of stuff. I believe the formula is 10 gallons of water for every inch of fish. And you need a filter, because goldfish are filthy creatures. And water conditioner. And probably some decorations so your fish doesn’t get bored. And when you clean the tank, you can’t just drain all of water and then refill it with freshwater. You need to drain some of it (preferably, while using your gravel vacuum to clean the gravel you put in the tank to look pretty) and then replace only it so the new water doesn’t shock the fish. Because shocking the fish may cause the fish to die. And don’t put your goldfish in a freshwater aquarium. Freshwater aquariums are warm, and goldfish are cold-water fish. A goldfish in warm water will “fail to thrive,” I was told. Well, by the time someone told me that I had already put Beethoven in a tropical fish tank. And he was not failing to thrive. He was already bigger than most of the other fish and he eating them. In the end, Beethoven lived for about 4 years and grew to be about 10” long. He ruled the freshwater tank. So, while I did a lot of things wrong, he lived a long and, if not happy, at least tyrannical life. But just remember, it’s not “just a goldfish” if you’re planning on taking good care of it. If you’re planning to just bring it home, put it in a bowl, and let it fend for itself, then it’s not too hard. But you’re not taking very good care of your pet. .
