Description

The spotlight goby is a small goby from the western central Atlantic, known from the Bahamas and Grand Cayman. It grows to only about 4 cm and has a slender body with a bright pale stripe, characteristic of the cleaner gobies. It lives on deep reefs between 13 and 45 metres, often on tube sponges, and behaves as a cleaner fish: it removes parasites and dead skin from larger fish, which come to be serviced. The fish is harmless to humans and is assessed as Least Concern (LC) by the IUCN.
