GOLDFISH (Cyprinus or Carassius auratus)  , a small See also:fish belonging to the Cyprinid See also:family, a native of See also:China but natur- See also:Telescope-fish . alized in other countries . In the See also:wild See also:state its See also:colours do not differ from those of a Crucian See also:carp, and like that fish it is tenacious of See also:life and easily domesticated . Albinos seem to be rather See also:common; and as in other fishes (for instance, the See also:tench, carp, See also:eel, See also:flounder), the See also:colour of most of these albinos is a See also:bright See also:orange or See also:golden yellow; occasionally even this shade of colour is lost, the fish being more or less pure See also:white or silvery . The See also:Chinese have domesticated these albinos for a See also:long See also:time, and by careful selection have succeeded in propagating all those See also:strange varieties, and even monstrosities, which appear in every domestic See also:animal . In some individuals the dorsal fin is only See also:half its normal length, in others entirely absent; in others the anal fin has a See also:double spine; in others all the fins are of nearly double the usual length . The snout is frequently malformed, giving the See also:head of the fish an See also:appearance similar to that of a See also:bull-See also:dog . The variety most highly prized has an extremely See also:short snout, eyes which almost wholly project beyond the See also:orbit, no dorsal fin, and a very long three- or four-lobed caudal fin (Telescope-fish) . The domestication of the See also:goldfish by the Chinese See also:dates back from the highest antiquity, and they were introduced into See also:Japan at the beginning of the 16th See also:century; but the date of their importation into See also:Europe is still uncertain . The See also:great See also:German ichthyologist, M . E . See also:Bloch, thought he could trace it back in See also:England to the reign of See also:James I., whilst other authors See also:fix the date at 1691 .

It appears certain that they were brought to See also:

France, only much later, as a See also:present to Mme de See also:Pompadour, although the de Goncourts, the historians of the mistresses of See also:Louis XV., have failed to trace any records of this event . The fish has since spread over a considerable See also:part of Europe, and in many places it has reverted to its wild See also:condition . In many parts of See also:south-eastern See also:Asia, in See also:Mauritius, in See also:North and South See also:Africa, in See also:Madagascar, in the See also:Azores, it has become thoroughly acclimatized, and successfully competes with the indigenous fresh-See also:water fishes . It will not thrive in See also:rivers; in large ponds it readily reverts to the coloration of the See also:original wild stock . It flourishes best in small tanks and ponds, in which the water is constantly changing and does not freeze; in such localities, and with a full See also:supply of See also:food, which consists of weeds, crumbs of See also:bread, See also:bran, See also:worms, small crustaceans and See also:insects, it attains to a length of from 6 to 12 in., breeding readily, sometimes at different times of the same See also:year .
