Congrogadus subducens
species of fish

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. 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.
It is the largest dottyback, reaching up to 45 cm (1 ft 6 in) in length. 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.
The carpet eel-blenny occasionally makes its way into the marine aquarium trade, but it is predatory and eats crustaceans and smaller fish.
Begin with the source’s own compact description: “Congrogadus subducens” is species of fish. The dossier treats that line as a proposition to test through Congrogadus, subducens and species, not as a finished interpretation.
Why this record matters
The phrase “species of fish” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Jul 29, 2026. The linked authority identifier is Q3336768. None of the 0 selected statements returned an explicit reference.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
