Congrogadus subducens

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, tidal flats and in brackish habitats.[1][2] Despite the 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.[3]

It is the largest dottyback, reaching up to 45 cm (1 ft 6 in) in length.[1][4] The 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.[1][2][5]

The carpet eel-blenny occasionally makes its way into the marine aquarium trade, but it is predatory and will eat crustaceans and smaller fish.[2][6]
