abdomen. It is quite generally distributed in flowing water in most of 

 the river systems of the Eastern, Middle and Southern states. It can be 

 kept with other freshwater fishes and thrives satisfactorily in the aquarium. 

 Its food is the same as that of the Sucker. 



THE MINNOWS 



The Minnows or cyprinoids are among the smallest of freshwater 

 fishes. There are many well-known species some of which thrive in the 

 aquarium, but others, whose natural habitat is swift-running water, are 

 difficult to keep alive except in tanks in which the water is constantly 

 changing. Some of the hardy forms are easily tamed and soon learn to 

 come to the surface of the water to be fed. The most generally distri- 

 buted species are the Black-striped minnow, Notropis procne; the Silver- 

 fin, Notropis analostanus. Fig. 50, and the Red-fin, Notropis cornutus.
