Western Atlantic: Gulf of St. Lawrence in Canada to North Carolina, USA. Mainly a near-shore marine species, but far inland populations occur in lakes in Nova Scotia in Canada and in Hudson, Delaware and Susquehanna River drainages (Ref. 5723).

Madurez: Lm ?  range ? - ? cm
Max length : 6.4 cm TL macho / no sexado; (Ref. 5723); common length : 4.1 cm TL macho / no sexado; (Ref. 12193); edad máxima reportada: 3.00 años (Ref. 12193)
Adults occur mainly along weedy bays and backwaters, entering brackish water and to a limited extent, fresh water (Ref. 3814). They feed along the bottom, primarily on diatoms, worms and crustaceans by sucking in the prey with a pipetting action (Ref. 27549). Males build, guard and aerate the nest where the eggs are deposited (Ref. 205).
