Video of juvenile Genicanthus personatus angelfish

The Masked Angelfish (Genicanthus personatus) is about as rare as angelfish go in our hobby - with a price tag to match. A video of what may be the smallest specimen in captivity surfaced over the weekend. See the video after the jump.

A short introduction about this species:

Genicanthus personatus are described as an Hawaiian endemic (most populous in deepwater and the northern islands where waters are cooler), although they have been recently reported from Midway Island.  G.personatus is, like all Genicanthus, a protogynous sequential hermaphrodite, meaning all specimens start as females but may develop into males.  This species is sexually dimorphic: females are white with black markings, while males white with orange and black markings.  See photos below.

The Masked Angelfish is rarely seen outside of public aquariums.  Read Charles Delbeek's Advanced Aquarist article about the Genicanthus personatus pair at Waikiki Aquarium.
