Very special thanks for the first photos of the Black coralgoby to Dr. Jürgen Herler.
Dr. Herler has taken his photos at Dahab, Egypt, Red Sea and at Gulhi Island, Maldives.
This species is found in shallow water regions such as protected reef flats and reef crests. It is highly specialized and prefers fine-branched corals such as Acropora selago and small tabulate colonies of Acropora hyacinthus. Seldom occurs in other Acropora species, such as A. acuminata, A. samoensis, A. eurystoma and A. valida. Due to its black colouration it is sometimes difficult to detect within the dark interstices of narrow-branched Acropora colonies.
