Fungus? Bac. Infection? Please help me find out

[Devildai]

Went on a family vacation and came back and my little guy was looking rough. I set up a QUICK quarantine tank (I am doing another one with no sand this was just an oh crap moment). Is this a bacterial infection or fungal or possibly something else? Any answers would be greatly appreciated.

Oh no!!
Bacterial likely along with slight ammonia burn and the recourse will be to change water- 35-% or so
Treatment preferably in quarantine will be both Maracyn and Maracyn 2
Increase aeration with air stone and monitor ammonia levels with a reliable ammonia kit
Expect slight cloudiness from Maracyn

Welcome to Reef2Reef!

Were there any other fish in with it? If so, how do they look?
Can you get us a clearer picture?
How long have you had this fish?
This sure looks like a secondary bacterial infection, but the question is, what brought it on?
