In a Name?
Do They Live?
Tadpole madtoms are found throughout Minnesota in streams, river, lakes, and other areas of quiet water over soft bottoms. They often occur in relatively shallow water (1-2 m deep) that may be clear to somewhat turbid (cloudy). They are attracted to underwater vegetation and other types of plant debris, such as tree branches and leaves. This fish often is found with white suckers, central stonerollers, creek chubs, common shiners, and black bullheads.
Big Do They Get?
Do They Eat?
This private, bottom-dwelling fish feeds mostly at night when it comes out of its daytime hiding places. It eats mostly aquatic insect larvae, waterfleas and other small crustaceans, and worms. Occasionally it consumes snails, fish eggs, and smaller fish.
