Fungus?

[Jacob._.merc]

Is this fungus? I have dealt with fungus before but have never had it this severe. I've had this fish for about 5 days and I've been treating him with meds for about 4 with melafix, putting in salt and turning the heat up. Any ideas what to do? Does it go away

I’d lower the temp to 78. Add some salt 1 tsp per g. Add some triple sulfa and api fungus cure. Stop the melafix.
