Blacksaddle Filefish (Paraluteres prionurus) ノコギリハギ also Mimic Filefish
The Blacksaddle Filefish looks very much like the Valentin’s Pufferfish. The Valentin’s Pufferfish is poisonous so not much likes to eat it. It is a filefish so it has a spine in front of the dorsal fin, which is lying flat in this picture. The dorsal fin is longer in the Blacksaddle Filefish. Amami

Here you can see the small dorsal and ventral fins on the Valentin’s Pufferfish. The Blacksaddle Filefish is a little harder to see but it has its dorsal spine up. Amami
