the domesticated form of the silver carass (Carassius auratus) and common aquarium fish. The first mention of goldfish breeding in China dates from the tenth to the 12th centuries; in 1611 it was brought to Portugal and later to England. In Japan the goldfish was first bred in the 16th century, and it appeared in Russia at the end of the 17th century. Selection by mutation and hybridization have produced a large number of breeds with attractive coloration, long fins, and protruding eyes, including the comet, shubunkin, veiltail, telescope, stargazer, lionhead, oranda, and pearl. When kept under proper conditions, goldfish reach sexual maturity in their second year; during spawning the female lays up to 2,000–3,000 eggs. The fish can live from 15 to 35 years in an aquarium. The goldfish feeds on moths, daphnids, shredded meat, earthworms, and various cereals and bread.
