Goldfish are now no longer restricted to royalty, being kept by the common people as well. Goldfish are curious fish that will quickly become bored without items or other fish to interact with. Goldfish are minimally territorial, so if your aquarium is already too small for one goldfish, it will certainly be too small for two or more. Color varieties of goldfish are caused by the varying amounts and arrangement of the pigment cells in the skin.
Goldfish are first raised in bowls indoors, allowing for the selection of mutations that might have gone unnoticed in a pond environment. Goldfish are normally active, swimming throughout the tank. They are social and can display schooling behavior when kept with the same goldfish for longer periods. Goldfish are often inhabit in association with freshwater vegetation.
Goldfish are similar to carp in many aspects other than appearance. They are popular pond fish, since they are, inexpensive, colorful, and very hardy. Goldfish are not a delicate fish as some other fish might be, they can survive in water that has some amount of waste or pollution in the water, but of course to a limit.
Common goldfish are a type of goldfish with no other matching from their ancestors other than their color. Common goldfish come in a variety of colors including red, orange/gold, white, black and yellow,red with white shades or ‘lemon’ goldfish. Common goldfish are social fish that prefer schooling. It can be kept in outdoor ponds throughout the year with similar care but they may become sluggish and stop eating in the winter.
Common Goldfish were first introduced to Japan in the 1500s, to Europe in the 1700s, and to the U.S in the mid 1800s. Common goldfish are hardy fish that can live and survive even in less than optimal conditions. Common goldfish, London and Bristol shubunkins, jikin, wakin, comet and sometimes fantail can be kept in a pond all year round in temperate and subtropical climates. The common goldfish are the species most raised in water gardens around the world (especially in Asia).
Breeding usually happens after a significant change in temperature, often in spring. Breeding often results in up to 1,000 eggs, with fry hatching in 5-6 days. Goldfish come from temperate regions of the world, and are therefore seasonal breeders.
Goldfish are quite intelligent creatures and will remember the person who feeds them regularly and will remember associations. Goldfish are coldwater fish that required enough room to move, breath and filtration, water circulation to remove their copious wastes.
