Maturity: Lm ?  range ? - ? cm
Max length : 10.0 cm TL male/unsexed; (Ref. 7251)
A solitary species (Ref. 26340) found on nearly vertical cliffs and drop-offs beyond outer reefs. Often upside-down. Retreats into recesses when alarmed (Ref. 9710). Has been reared in captivity (Ref. 35420). Most common in water more than 30 m deep. Gradually replaces G. loreto at depths of 15-30 m (Ref. 26938).
