Chromis anadema is a newly discovered species that was identified through a closer investigation of the paletail chromis, C. xanhura, a common group of fishes. This short-tailed double bar chromis has distinct juvenile and adult characteristics. It was found on remote oceanic islands in the southern territories of Japan, near Ishigaki, Okinawa Prefecture. Despite its discovery in this area, it has also been collected from the Northern Philippines, Guam, and the Marquesas Islands, indicating that it has a wider distribution.
Juvenile C. anadema are silvery blue with yellow fins, while adults are less colorful with bolder and blacker double bars around the head and grey or black fins. This species, like many Chromis, undergoes significant changes in coloration during development.
