something on the filefish's mouth

Not sure what it is because it more or less looked like he got into something and it's just stuck on his mouth. Eating fine but noticed he's a lil less active then before. My first thought was a fungus but when you look at it, looks like a piece of shell. The cleaner shrimp just shed last night an maybe at the shedding? what do you guys think? I have quarantine at ready

 

Just leave him be for now. I wouldn't stress the little guy out by means of quarantine. IMO, it would do more harm than good. At least give it a few days before taking any action. He's nice looking.

 

thank you! yea I'll leave him be then. Was trying to see if it was early signs of something so I can stop it before it got worse. I've heard stories of them turning on corals and destroying lps but he's left all mine alone and thank god for it be cut hes such a beautiful amazing fish

 

Update just something he got into. It was gone this morning.

 

yay! good news! that is a cool looking fish! glad it's behaving for you
