Rare, usually found on deeper vertical cliffs on the seaward reef. At the time this species was described, it was known only from specimens found at Kwajalein, but it likely is more widespread.
Some recent photos by Jay Lord suggest that the juvenile of this species is more brown in color but with the same banding. The intermediate (middle shot of the three posted below) appears part way in between the other two photos. The change in color of the tail seems particularly telling.
Apparently a juvenile, about 25mm long.
