Where are the File Spurs on the tail? Orange "File" fish have a rasp looking barb on their tail and they a very visible, even from the top! So what are you basing your "Findings" on? Otherwise nice guess, but I would say wrong! Buzzzzzzzzz!
Filefish don't have a file spur on their tail. The name filefish comes from their rough skin (similar to triggerfish skin) and from the first dorsal spine.
