[3] The eastern blacknose dace is found across the southeast portion of Canada and down along the United States' east coast.
Blacknose dace live in rocky streams and rivers where they feed upon small invertebrates and microscopic biological matter and provide forage for larger fish.
[8] This fish tends to inhabit headwaters, creeks, and small rivers with swiftly moving water.
[9][5][10] Young fry forage in shallow silty water while adults move into riffles and deep eddying pools to find invertebrates.
[5][9] Eastern blacknose dace spawning takes place between May and June and occurs in shallow water over gravel riffles.
[5] During this breeding season, the male develops nuptial tubercles on various parts of the body including the head and fins.
Eggs are deposited into crude nests which are depressions in the gravel created by vigorous movement during spawning.
