Description
Grammonus ater, also known as the Black Cusk-eel, is a deep-water marine fish found in the Eastern Atlantic and Mediterranean. This benthic species typically inhabits caves and crevices, preying on small crustaceans and invertebrates. It is not suitable for typical home aquariums due to its specialized deep-water habitat requirements.
