The term carp is a generic common name for numerous species of freshwater fish from the family Cyprinidae,a very large clade of ray-finned fish mostly native to Eurasia. While carp are prized quarries and are valued as both food and ornamental fish in many parts of the Old World,they are generally considered useless trash fish and invasive pests in many parts of Africa,Australia and most of the United States.

An aquarist is a person who manages aquariums,either professionally or as a hobby. They typically care for aquatic animals,including fish and marine invertebrates. Some may care for aquatic mammals. Aquarists often work at public aquariums. They may also work at nature reserves,zoos,and amusement parks. Some aquarists conduct field research outdoors. In business,aquarists may work at pet stores,as commercial fish breeders,or as manufacturers. Some aquarists are hobbyists,also known as "home aquarists," who may vary in skills and experience.
The comet or comet-tailed goldfish is a single-tailed goldfish bred in the United States. It is similar to the common goldfish,except slightly smaller and slimmer,and is mainly distinguished by its long deeply forked tail. Comet goldfish tend to have a diverse variety of colors,unlike the common goldfish.
The term coldwater fish can have different meanings in different contexts.
The Ranchu is a hooded variety of goldfish native to Japan. It is referred to as the 'king of goldfish" by the Japanese. Maruko more commonly refers to the egg-fish goldfish.
Fishkeeping is a popular hobby,practiced by aquarists,concerned with keeping fish in a home aquarium or garden pond. There is also a piscicultural fishkeeping industry,serving as a branch of agriculture.
Aquarium fish feed is plant or animal material intended for consumption by pet fish kept in aquariums or ponds. Fish foods normally contain macronutrients,trace elements and vitamins necessary to keep captive fish in good health. Approximately 80% of fishkeeping hobbyists feed their fish exclusively prepared foods that most commonly are produced in flake,pellet or tablet form. Some fish foods also contain additives such as sex hormones or beta carotene to artificially enhance the color of ornamental fish.
The common goldfish is a breed of goldfish and a family of Cyprinidae of order cypriniforms. Goldfish are descendants of wild carp from East Asia. Most varieties of fancy goldfish were derived from this simple breed. Common goldfish come in a variety of colors including red,orange,red/white,white/black,yellow/white,blue,grey/brown,olive green,yellow,white,and black,with the most common variation being orange,hence the name. Sometimes,the brightness,duration,and vividness of the color may be an indication of the fish's health status,but not always,as manifold waters conditions facilitate the apparent discoloration.
The Pearlscale is a spherical-bodied fancy goldfish with doubled finnage similar to the fantail.
Carassiusis a genus in the ray-finned fish family Cyprinidae. Most species in this genus are commonly known as crucian carps,though this term often specifically refers to C. carassius. The most well known is the goldfish. They have a Eurasian distribution,apparently originating further to the west than the typical carps (Cyprinus),which include the common carp.
A freshwater aquarium is a receptacle that holds one or more freshwater aquatic organisms for decorative,pet-keeping,or research purposes. Modern aquariums are most often made from transparent glass or acrylic glass. Typical inhabitants include fish,plants,amphibians,and invertebrates,such as snails and crustaceans.
The Prussian carp,silver Prussian carp or Gibel carp is a member of the family Cyprinidae,which includes many other fish,such as the common carp,goldfish,and the smaller minnows. It is a medium-sized cyprinid,and does not exceed a weight of 3 kilograms (6.6 lb) and a length of 45 centimetres (18 in). They are usually silver,although other color variations exist. They are omnivorous and feed on plankton,invertebrates,plant material and detritus. Originally from Siberia or central Europe,they have been introduced to and are now inhabiting lakes,ponds,and slow-moving rivers throughout Europe,North America,and Asia.
The White Cloud Mountain minnow is a hardy species of freshwater fish and coldwater fish often kept in an aquarium. The species is a member of the carp family of the order Cypriniformes,native to China. The White Cloud Mountain minnow is practically extinct in its native habitat,due to pollution and tourism. It was believed to be extinct for over 20 years in 1980,but an apparently native population of this fish was discovered on Hainan Island,well away from the White Cloud Mountain. They are bred in farms and are easily available through the aquarium trade. However,inbreeding in farms has led to genetically weak stock that is vulnerable to disease and prone to physical deformities.
The Japanese white crucian carp,also known as Japanese carp,white crucian carp,or gengoro-buna,is a species of freshwater fish in the carp family. It is found in Japan and,as an introduced species,in several other countries in Asia. This fish is closely related to the commonly known goldfish.
The crucian carp is a medium-sized member of the common carp family Cyprinidae. It occurs widely in northern European regions. Its name derives from the Low German karusse or karutze,possibly from Medieval Latin coracinus.
The ginbuna,sometimes referred to as silver crucian carp or Japanese silver crucian carp,is a species of freshwater fish in the carp family. It is native to lakes and rivers in Japan.
