This fish is hardy but undesirable in the aquarium. It is ugly in 

 appearance and will root out the planting in an aquarium. Its one 

 virtue is that it supplies food to many a poor man's table. 



Goldfish (Carassins aiiratus) 



Appcarciiicc. Full bodied, very deep in the middle; sometimes 

 weirdly shaped; protruding eyes or abnormal fins; black, brown, 

 white, or pale gold to red in color, the light colored young often 

 with temporary black spots or blotches. 



Size. 300 mm. or more in length. 



Habitat. Warm, shallow lakes and rivers, where introduced 

 by man. 



Breeding Habits. During June the males pursue spawning 

 females. The females swim into dense mats of vegetation where, 

 often with much flapping at the water surface, some of the males 

 fertilize the eggs. Accompanying goldfish of both sexes eat all the 

 eggs they can find. 



Food. Similar to that of the carp; anything vegetable or animal 

 that they can swallow. 



Although attractive in color, goldfish are undesirable in the 

 aquarium when they are more than 60 or 70 mm. long, for their 

 hoglike rooting dislodges all aquarium plants and their huge appe- 

 tites result in their fouling the water as do few other fishes. 



Western Blacknose Dace 

 (Khifiichthys atratiiliis iiielcagris) 



Appearance. Slender; dark gray or grayish brown above, silver 

 beneath; back speckled with dark scales, frequently with additional 

 black spots caused by parasites lodged beneath the skin; the pec- 

 toral and anal fins rather large; two minute, fleshy feelers (barbels 

 on upper jaw) . 



Size. 90 mm. in length. 



Habitat. Rapid streams. 



Breeding Habits. The fish mate in the riffles of a stream. There 

 is no nest and no care of the eggs, which are merely released over
