Clownknife help

[Reedjasper]

My 24" clown knife fish looks like his toungue turned outside his jaw I hear from opening his mouth to wide . Have read ways to try to fix it but I doubt any I have read will help. Anyone else have luck fixing this issue? I have had him for 12 yrs or so would hate to lose him

Thanks for looking though! Sucks it doesn't look super serious in the picture but in person it looks a lot worse and he isn't eating so definitely not good!
