The Wolf Eel is often referred to as a Blenny. However, it is a pseudochromid (Dottyback). Its common names include Carpet Eel Blenny, Eared Eel Blenny, and Green Wolf Eel. Its body is a brownish color with highlights of green.
It requires a 125 gallon or larger aquarium with plenty of hiding places. The aquarium should have a tight-fitting lid to prevent escape. The Wolf Eel may be kept in a reef aquarium, but will eat smaller fish and crustaceans.

Its diet should include meaty foods such as small marine fish, chopped clam, and prawns in its diet.
