gravel. There seem to be spawning areas, however, which one male 

 defends from all others. 



Food. Aquatic insects and possibly algae, but it will learn to 

 eat dried shrimp and similar prepared fish foods. 



Since this species is a stream fish it requires more oxygen than 

 many others and should be kept in running water if possible. It 

 might be induced to spawn in an aquarium, its spawning temper- 

 ature being 70° F. 



FiNESCALE Dace (Pfrille neogaea) 



Appearance. Slender, with a single dark stripe along the length 

 of the body, the male with bright red on the lower part of its sides; 

 the mouth large and straight; the body covered with scales so fine 

 as to be seen only with the aid of a lens. 



Size. Adults reach almost 100 mm. in length. 



Habitat. Chiefly the bog streams and small lakes of all but the 

 lower third of the lower peninsula of Michigan. 



Food. Aquatic insects and probably algae. Will learn to eat 

 dried fish foods. 



This fish proves to be relatively hardy in the aquarium once it 

 has become adjusted to the new conditions. 



Northern Redbelly Dace (Chrosomtis eos) 



Appearance. Very much like the preceding species, but with a 

 shorter snout and a more oblique mouth. 



Size. Adults, about 65 mm. long. 



Habitat. Bog ponds and bog streams, beaver ponds, and similar
