Habitat. Running streams or clear lakes where the sand and 

 gravel are clean and free of vegetation. Increasingly coninion in 

 the southern peninsula of Michigan. 



Breeding Habits. These minnows seem to spawn in schools and 

 lay their adhesive eggs in clusters on submerged logs and other 

 objects near shore. 



Food. Chiefly aquatic msects and various more or less micro- 

 scopic plants and animals. 



Although relatively uncommon in Michigan, this minnow prom- 

 ises to be an interesting addition to the large aquarium. 



Blackchin Shiner (Notropis heterodon) 



Appearance. The chief distinguishing marks are the black-tipped 

 chin and a dark band running from the nose back through the 

 eye to the tail. The adults are noticeably humpbacked. The color 

 is dusky olive above; dull silver along the sides, except for the 

 black stripe; and silvery white, tinted with orange, underneath. 



Size. Adult length about 47 mm. 



Habitat. Smaller lakes and occasionally weedy streams. 



Breeding Habits. This species spawns in May and June. 



Food. Preferably small crustaceans, such as water fleas, but 

 other animals and plant material are also eaten. 



Once used to an aquarium, this fish is relatively hardy. As with 

 many other captive fishes, occasional meals of living water fleas, 

 mosquito larvae, etc., arc important.
