The finescale dace (Chrosomus neogaeus) is a species of freshwater fish in the family Cyprinidae of order Cypriniformes.

[3] Beaver ponds provide an excellent habitat, as they are found hidden in the safety among sunken logs and downed brush.

[3] Their diet also includes a variety of crustaceans, plankton, algae, and in the Northern parts of Minnesota, fingernail clams.

[7] Finescale daces are predated on by a multitude of species including diving beetles, mink, brook trout, and kingfishers, but however, are not consumed by humans.

Their resiliency and sturdiness make them a great species for the bait industry in Wisconsin, Minnesota, and Canada, as well as pets in home aquariums.

[3] Breeding begins in April and ends in June, when the internal temperature of the streams heat to at least 15 degrees Celsius.

The yellow and red colors exhibited in the pigments on the underside of a male's body during breeding season alerts the female of sexual readiness.

[3] The pair will shoot into the indentation together and the female will proceed to lay her eggs while the male begins to fertilize them with his sperm.
