The carpet eel-blenny (Congrogadus subducens), 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.Goemans, B. (November 2008). Dottybacks—Choose Carefully! TFH Magazine. Retrieved 12 November 2016. 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.Reefkeeping (April 2005).

It is the largest dottyback, reaching up to in length.Lieske, E., and Myers, R. (1999). Coral Reef Fishes. 2nd edition. Princeton University Press. Its colour is very variable (green, brown, black, or bluish; often with spots or blotches) and the carpet eel-blenny can change it to match the surroundings.Tan, R. (2008, updated October 2016). Carpet eel-blenny. Wild Singapore. Retrieved 12 November 2016.
The carpet eel-blenny occasionally makes its way into the marine aquarium trade, but it is predatory and eats crustaceans and smaller fish.Reefkeeping (April 2004). What the Heck is That? The Genus Congrogadus. Retrieved 12 November 2016.
