variety of the Com-mon Tench originally bred in Silesia, and is of bright orange color, spottedwith brown dots on the sides, fins and tail. The small fishes, Fig. 42,are so nearly transparent when viewed towards the light that all the interiororgans and the very functions of life may be seen through the transparentsubstance of the skin. When viewed with the light at the back of the ob-server, the colors are most charming and resemble an opal more than anyother object. With the exception of the Goldfish and the Paradise fish,the Tench is probably the handsomest aquarium fish, very hardy, easilykept, and perfectly harmless, and should find a place in every aquarium.It may be fed with the usual goldfish foods. Its culture should be en-couraged, as it is a very fine pond fish of lively habit. THE CARP The Carp, Cyprinus carpio, is one of the most widely distributed ofthe pond fishes. A number of forms have been produced by Europeanbreeders of which the following are the more interesting.

FIG 43 — Young Scaled Carp, Cyprinus carpio communis 78 SOME FRESHWATER AQUARIUM FISHES The Scaled Carp, Cyprinus carpio communis, Fig. 43, was originallyintroduced into Europe from Central Asia, and has been extensively culti-vated in natural and artificial ponds and slow-flowing streams. It is dis-tinguished from its kindred breeds by its regular concentrically arrangedscales. The color is variable but is usually brownish with a bluish tingealong the back and a golden or coppery reflection along the scales. The Mirror Carp, Cyprinus carpio specularis, Fig. 44, has very largeirregularly disposed scales. Some forms have very few scales, sometimesrestricted to one row along the lateral line, or in others to a line along theback with a tew large scales scattered at random over the sides. Some havea dorsal, a ventral and a lateral line of scales on an otherwise scaleless body,these differences being produced by the careful selection and propagationof breeders.
