カスミチョウチョウウオ

The fish with a yellow and white body is the pyramid butterfly fish. It lives to the south of Wakayama and can grow up to be 15 cm in length.

It lives in colonies around coral reefs where the current is relatively strong. It feeds on planktons that come by on the current.  When they sleep at night, they stay still near a rock and turn black.
