It has small sesame-like black spots on its pale yellow body. A black band runs vertically over the eye. The edge of the obi is white.
The dorsal fin has a jagged silhouette, yellow, black, and white from the body.
Found in shallow reef areas. It eats small benthic animals and seaweed.
It is seen as a dead migratory fish along the Kanto coast.
I found him swimming alone in Arasaki after the typhoon passed. It was a small individual, and foraged while drifting between rock crevices. There is no group nearby, so it may be an individual that has wandered into the area.
