SOME FRESHWATER AQUARIUM FISHES The Golden Carp, Cyprinus carpio aureus, is an albino form of the Scaled Carp, atone time extensively bred in Germany for ornamental pur- poses but has been largely superseded by the Common goldfish. The Crusian Carp, Carassius carassius. Fig. 45 is a variable form closely related to Cyprinus carpio and differs somewhat in form and in the absence of barbels. It is a shorter fish of more hunch-backed appearance. Its habits are also similar to the common carp, and it will live in localities wherein the impurities are sufficient to destroy most other of the fresh- water fishes. It is con- sidered to have been the form from which the goldfish, Carassius aura- tus, was derived, this fish being of Chinese and Corean origin and ex- traction. Other forms of the Crusian Carp are FIG. 45-Young Crusian Carp, Caras^im carassius Q moks, C. gibelio, C. oblongus and C. humilis, all variations produced by domestication, selection and breeding. Small specimens of all the Carp breeds make interesting aquarium fishes. In 1877, and for some years thereafter, attempts were made to generally introduce the Scaled and Leather Carp in the United States, as their easy propagation recommended them for regions remote from a supply of better-flavored fishes, but the results were not satisfac- tory and in the past years the attempt has been abandoned. The introduction of carp into many streams is now forbidden by acts of state legislation. All carp will excavate the banks of ponds in search for food which consists of the tender shoots and roots of aquatic plants and the tiny ento- mostraca and insects of fresh water, for which it burrows into the mud and the banks of streams and ponds. In the aquarium it will thrive on goldfish foods. The carp is destructive to the spawn of other THE TES
