Các tia vây lưng cứng (tổng cộng) : 7; Các vây lưng mềm (tổng cộng) : 10; Tia cứng vây hậu môn: 1; Tia mềm vây hậu môn: 8. This species is distinguished by the following characters: D VI+I,10; A I,8; head and body are naked; presence of a deep curved groove on isthmus; body and caudal peduncle slender (depth 37-41.2% and 13.8-14.7% SL, respectively); juveniles with rounded head, large adults slightly hump-headed; colour in juveniles and adults uniformly black, including iris; very small species (< 2.8 cm SL); females of breeding pairs usually significantly larger than males, recorded smallest highly gravid female is 1.85 cm SL (Ref. 94082).
Body shape (shape guide): short and / or deep; Cross section: compressed.
Facultative air-breathing in the genus (Ref. 126274); 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 (Ref. 94082).
