The common dace is found in rivers and streams, sometime occurring in lakes or in the brackish water at the mouths of rivers.[1] It is a surface dwelling fish which gather in shoals of adults in the lower reaches of rivers and backwaters during the winter. Some adults remain upstream in the spawning grounds all winter as well. At spawning time, in March and April, they migrate up stream to lay their pale yellow eggs on shallow gravel beds in fast flowing streams, the eggs attach to gravel and stones.
