Carassius
''Carassius ''is 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 (''C. auratus''). They have a Eurasian distribution, apparently originating further to the west than the typical carps (''Cyprinus''), which include the common carp (''C. carpio''). Species of ''Carassius'' are not particularly close relatives of the typical carps of ''Cyprinus'', but rather form a more basal lineage of the subfamily Cyprininae.de Graaf, Martin; Megens, Hendrik-Jan; Samallo, Johannis & Sibbing, Ferdinand A.

Crucian Carp
The crucian carp (''Carassius carassius'') 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'' (a kind of river fish). Distribution The crucian carp is a widely distributed European species, its range spanning from England to Russia; it is found as far north as the Arctic Circle in the Scandinavian countries, and as far south as central France and the region of the Black Sea. Its habitat includes lakes, ponds, and slow-moving rivers. It has been established that the fish is native to England and not introduced. The crucian carp is a medium-sized cyprinid, typically in body length, and rarely exceeds in weight over , but a maximum total length of has been reported for a male,Koli, L. 1990 Suomen kalat. ishes of Finland Werner Söderström Osakeyhtiö.

Carassius Auratus
The goldfish (''Carassius auratus'') is a freshwater fish in the family Cyprinidae of order Cypriniformes. It is commonly kept as a pet in indoor aquariums, and is one of the most popular aquarium fish. Goldfish released into the wild have become an invasive pest in parts of North America. Native to East Asia, the goldfish is a relatively small member of the carp family (which also includes the Prussian carp and the crucian carp). It was first selectively bred for color in imperial China more than 1,000 years ago, and several distinct breeds have since been developed. Goldfish breeds vary greatly in size, body shape, fin configuration, and coloration (various combinations of white, yellow, orange, red, brown, and black are known). History Various species of carp (collectively known as Asian carp) have been bred and reared as food fish for thousands of years in East Asia. Some of these normally gray or silver species have a tendency to produce red, orange or yellow ...

Carassius Langsdorfii
The ginbuna (''Carassius langsdorfii''), sometimes referred to as silver crucian carp or Japanese silver crucian carp, is a species of freshwater fish in the carp family (family Cyprinidae). It is native to lakes and rivers in Japan. Description Ginbuna is a deep- and thick-bodied fish with a terminal mouth and a large caudal fin. It possesses 5 anal fin rays, 41–57 gill rakers, and has 28–31 large lateral line scales. It reaches a maximum length of . This species is parasitized by myxozoan cnidarians of the genus '' Myxobolus'', which infest their gills. Taxonomy The ginbuna can be difficult to distinguish from the common goldfish (''Carassius auratus''), to which it is closely related. In fact, it has often been treated as a subspecies of goldfish. However, current genetic data suggests that the ginbuna is a distinct species. The ginbuna commonly hybridizes with other species in its genus where they come into contact, as well as with the closely related common c ...

Carassius Gibelio
The Prussian carp, silver Prussian carp or Gibel carp (''Carassius gibelio''), 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 and a length of . They are usually silver, although other color variations exist. They are omnivorous and feed on plankton, invertebrates, plant material and detritus. Originally from Siberia, they have been introduced to and are now inhabiting lakes, ponds, and slow-moving rivers throughout Europe, North America, and Asia. Prussian carps are highly invasive fish species in areas outside its native range. They reproduce and spread rapidly. In 2020, scientists demonstrated that a small proportion of fertilized Prussian carp eggs ingested by waterfowl survive passing through the digestive tract and hatch after being retrieved from the feces. Birds exhibit strong preference for fish eggs, while cyprinids produ ...

Carassius Cuvieri
The Japanese white crucian carp, also known as Japanese carp, white crucian carp, or gengoro-buna (''Carassius cuvieri''), is a species of freshwater fish in the carp family (family Cyprinidae). 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. Description This is a medium fish, growing up to 50 cm, with a broad head and a blunt snout. The lips are fleshy, and lacking barbels. The body is deep and laterally compressed, with a distinctly humped back. The scales are large and cycloid in shape, with a complete lateral line. Serration is present on the last ray of the dorsal and anal fins, and the caudal fin is forked. Taxonomy The Japanese white crucian carp was formerly considered a subspecies of wild goldfish, and was classified as ''C. auratus cuvieri''. It has now been elevated to species rank, however some authors are in disagreement. Genetic studies using mitochondr ...
