Graysbys are light brown or gray in color, with small brown or red spots covering its body. An additional three to five spots often appear along the base of the dorsal fin.

Graybys are found in coral reefs, in areas where they can hide in caves and crevices. They are most active at night, when they come out of their hiding spots to feed on fish and crustaceans.


Graysbys feed on small fish and crustaceans such as crab and shrimp.


Graysbys can reach up to 16 inches.


The graysby’s range includes the Western Atlantic Oceans from North Carolina to southern Florida, as well as the Gulf of Mexico and the Caribbean Sea.

A Note From the Caretaker

Our Graysby comes to the back wall of the exhibit and sits at the surface when I feed the tank. It waits for me to drop a piece of food in front of it, then snatches it up very quickly.
