The grouse goby ( Elacatinus evelynae ) lives in the coral reefs of the Bahamas , the Lesser Antilles and northern South America . The goby-like fish there, like related species from the genus Elacatinus, play the ecological role of the cleaner wrasse from the Indo-Pacific , which is missing in the Atlantic. They also resemble cleaner wrasse in their drawing.
Shark-nosed gobies maintain permanent cleaning stations on raised, massive hard corals of the genera Colpophyllia , Diplora and Montastrea at depths of up to 30 meters and live there individually, in pairs or in groups, often together with the cleaner goby ( Elacatinus genie ), which also cleans fish. Shark-nosed gobies probably feed exclusively on small parasitic crustaceans, which they eat off their “customers” skin. The diurnal fish hide in their coral hiding place at night.
The grouse gobies are only three centimeters long and are bred commercially for seawater aquariums .
