It’s about 3-4 months old it has 2 clownfish and a Fiji fox face

Do you have any inverts that could have done this? Is he displaying any strange behavior? Did you adding anything new to the tank recently?

 

[Tylerc33]

I don’t think anything would have done it to him. And nope he was the last thing I added and he’s acting completely normal

I am thinking injury. Keep an eye on it. It would be a good idea to add kana + furan + focus to your feed to avoid a possible bacterial infection.
