habitats E. ongus occurs in shallow water on coral reefs and rocky substrata. It occurs primarily on inner coastal and lagoon reefs, even in brackish water, where it frequents ledges and caves at depths of 5 to 25 m. 
Distribution E. ongus is widely distributed in the Indo-Pacific region, from the east coast of Africa (northern Mozambique to Kenya) to the Ryukyu and Marshall Islands and south to Fiji, New Caledonia and northern Australia. 
Utility This cryptic species is not very common, it is also of some interest to fisheries in Japan.
