Habitat and biology
The blue velvet angelfish is an extremely shy fish which often hides among rubble and rocks, particularly when alarmed, on seamounts.[4]
Systematics
The blue velvet angelfish was first formally described in 2012 by Kang-Ning Shen, Hsuan-Ching Ho, and Chih-Wei Chang with the type locality given as Bligh Water, east of Yasawa Island in Fiji.[5] The specific name honours Deborah Smith, wife of Walt Smith, a collector and trader in the aquarium trade who collected the type series. Within the genus Centropyge this species is considered to be incertae sedis.[6] It was initially identified as C. nox but the blue tint and subsequent genetic analysis at the National Taiwan University confirmed it was a new species.[2]
