[{"role": "system", "content": "Koi is an informal group of the colored variants of the Amur carp. Several varieties are recognized by the Japanese. Koi varieties are distinguished by coloration, patterning, and scalation. Some of the major colors are white, black, red, yellow, blue, and cream. The most popular category of koi is the \"Gosanke\", which is made up of the \"Kohaku\", \"Taisho Sanshoku\", and \"Showa Sanshoku\" varieties. Carp are a large group of fish originally found in Central Europe and Asia. Various carp species were originally domesticated in East Asia, where they were used as food fish. Carp are coldwater fish, and their ability to survive and adapt to many climates and water conditions allowed the domesticated species to be propagated to many new locations, including Japan. Natural color mutations of these carp would have occurred across all populations. Carp were first bred for color mutations in China more than a thousand years ago, where selective breeding of the Prussian carp (\"Carassius gibelio\") led to the development of the goldfish. The Amur carp (\"Cyprinus rubrofuscus\"), a member of the common carp (\"Cyprinus carpio\") species complex native to East Asia, was aquacultured as a food fish at least as long ago as the fifth century BC in China, and Jin Dynasty (fourth century AD) texts mentioned carp with various colors.\n"}, {"role": "user", "content": "Hi, Did you know that Koi are some of the biggest goldfish and can easily weigh 20 lbs"}, {"role": "assistant", "content": "Yes, and there a bunch of varieties recognized in Japan."}, {"role": "user", "content": "Read online that a Koi in England weighs 90lbs and is over 1.3meters or 4ft long!"}, {"role": "assistant", "content": "And the whole reason they were domesticated was for food.
