Growth is stimulated by a higher protein diet, larger tank size, warmer temperatures, and higher water quality. The growth rate of most Goldfish species is influenced by space, diet, and temperature, but is typically about 2-3 centimeters (1 inch) per year. How fast/slow should you expect your Goldfish to grow? ![]() Goldfish have a life expectancy of 15 years, with cases of individuals living 20 years or more in an aquarium with excellent care and conditions. Goldfish turning white Goldfish Lifespan How Long Do Goldfish Live For? Their hardy health and tolerance make Goldfish an excellent choice for an inexperienced aquarist. Some people even keep goldfish in tanks with no temperature control or filtration. They can withstand a variety of water quality and temperatures in an aquarium or a pond. ![]() Goldfish are quite hardy, with Common Goldfish being one of the easiest species to keep. The Common Goldfish is often confused with the Comet Goldfish and “London type” Shubunkin Goldfish. The caudal fin is forked and the dorsal fin is slightly concave. The Common Goldfish has an elongated, flat body with a wide, short head and erect fins. Individuals with a metallic orange sheen are most notable. Besides gold, color mutations of red, yellow, white, brown, black, and any combination of those have been produced. Over many centuries, the extensive breeding of Goldfish and selection for mutations has created numerous variations in coloration and appearance. Fishkeepers began to specifically breed individuals displaying this color to produce ornamental fish for manicured garden ponds.īy the 16th century, Goldfish had spread to Japan, by the 17th century, they had been traded to countries in Europe, and by the 19th century, Goldfish had made their way to America. when a natural genetic mutation produced fish of a yellowish-orange color. Goldfish were developed as a species in China and were originally silver or gray in color until 265-420 A.D. This species inhabits rivers, lakes, ponds, and even ditches of stagnant or slow-moving water, where they have an omnivorous diet of plants, crustaceans, and insects. Genetic research recently concluded that modern Goldfish are descendants of a wild carp species indigenous to Central Asia known as the Prussian Carp, Silver Prussian Carp, and Gibel Carp. Goldfish were originally thought to be descended from the Crucian Carp, a species found widely-spread across Europe. Minimum tank size (as adult): 57 Liters (15 gallons). ![]() Water conditions: Freshwater, 18 – 22 degrees Celcius (65 – 72F), 6 – 8 pH, 5 – 19 dGH.
