Fish The Johnny Darters 
seen one walk around the aquaruim on his fins as if 
they were little fan-shaped feet; and when swim- 
ming, the fins are used as a bird uses its wings. 
There are many species of darters, some of them 
the most brilliantly colored of any of our fresh water 
fishes. In the breeding season the male is especi- 
ally brilliantly colored.

CARE 
Since the darters live in swift streams, they thrive 
best in an aquarium which has running water; 
however, if the aquarium is well-balanced, shallow 
and broad, and contains good oxygen-producing 
plants, the darter will live in it for a time. The 
aquarium should be kept cool for the darters cannot 
stand hot weather nor warm water. 
Their natural food consists of the small creatures 
of the water, but they thrive when fed with small 
earthworms, and meal worms, and will learn to eat 
crissel and the fish foods.
