FBname: Orange margin butterflyfish
Comments: This species was observed in areas of basalt substrata (e.g., basalt talus, blocky lava, lava tubes and pillows, basalt boulders) and in limestone habitats (primarily limestone holes and ledges).  Observed also in the vicinity of an unidentified antipatharian coral, near <i>Cirrhipathes spiralis</i> (Linnaeus), and <i>Antipathes dichotoma</i> Pallas. This species in association with limestone ledges and discontinuities representing ancient shorelines, almost in all cases, the fish were found underneath, inside of, or in close proximity to small undercut overhangs or caves, often swimming upside-down in association with the roof of the overhangs and caves. However, there are no obvious associations with other species, such as antipatharian corals, other corals and sessile invertebrates, or particular fish species; although certain species, such as <i>Odontanthias fuscipinnis</i> (Jenkins, 1901) and the wrasse <i>Bodianus sanguineus</i> (Jordan & Evermann, 1903), these species tend to occupy the same depth and habitat. Collected with hand nets during deep dives using mixed-gas, closedcircuit rebreathers (Ref. 116690).  FishBase common name agreed by authors.
