SOME FRESHWATER AQUARIUM FISHES 

THE BRILLIANT CHUBSUCKER OR MULLET 
This fish is known as the Chubsucker, Erimyzon sucetta, Fig. 49, and 
may be recognized by its clear green back, lemon-yellow sides, and white 

FIG. 49—Chub-sucker or Mullet, Erimyzon sucetta 
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 
dificult 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.
