The red fish is the big-eyed soldierfish. It lives to the south of mid-Honshu. They are often found in coral reefs south of AmamiOshima and can grow up to be 20 cm in length.

They live in shallow waters around rocky areas and coral reefs. During the day, they stay still and hide in holes of rocks but during the night, they come out and swim around.

Its lower jaw sticks out further than the top jaw, making it easy to distinguish from other fish of the same family.
