About this species

The carpet eel-blenny, also known as the green wolf eel or green wolf eel blenny, is a relatively large species of dottyback found in coastal parts of the Indo-West Pacific, including coral reefs, among rocks, seagrass beds, and tidal flats, and in brackish habitats. Despite the common names, it is unrelated to the true wolf eel of the North Pacific, the true eel of the order Anguilliformes, and the true blennies of the suborder Blennioidei.
