Habitat and Ecology

Habitat and Ecology
This reef-associated species inhabits rocky reefs to depths of 21m. It is usually found near Eucidaris thouarsi (Robertson and Allen, 2006). According to Dominici-Arosemena and Wolff (2006), this fish is present in deep rocky walls and reefs, zones of massive coral and exposed shallow rocky reef in Gulf of Chiriqui, Panama. In Gorgona Island, Colombia (Rubio 1986), this species is occasionally found in intertidal pools and coraline substrate.
