White lines on my Oscar just showed up

What are these white lines on my Oscar. I woke up the morning and saw them. He is acting normal and not stressed out... He is eating fine as well. It's on both sides of him or her...

Is it fuzzy? Hard to tell but it looks like it's dangling off the body in some areas?

Edit- Okay not Columnaris. I spoke too soon. Its an external parasite from the looks. Your tank looks a bit dirty so that may have caused it

what your fish is suffering from is a fungal infection called Columinaris. Left untreated, it can be deadly, but it's pretty slow moving, so as long as you act now your Oscar will be fine. Just buy some anti-fungal treatment from your local petstore (the fish kind of course), and treat him. Columinaris can be spread from fish to fish, so I would suggest treating the whole tank rather than quarantining and treating, but it's really up to you

Columnaris is a bacterial infection.
