Fungal/bacterial infection?

[Hammer100]

I have a cardinal that suddenly stopped eating yesterday. This morning he didnt eat so i got a closer look at him and he seems to have what looks like a "cottonish" looking sheen on his side. I dont see any flashing or white spots and other than not eating its behavior has not changed.
I also have 3 chromis in the tank and they look/act fine.
I have stable parameters but i did start dosing NOPO4x to bring down my phosphate level on monday.
I am also running Zeovit....too much carbon dosing???

Did you qt? The cottonish sign sounds like uronema.

treatment?

Now looks like a lump on the left side...

Any other fish in tank? @Humblefish I think your assistance is needed.

Can you post a photo of the fish and this lump?

 

[Hammer100]

I'll try to get a pic...only three chromis that look fine and the sick Cardinal...handful of snails

Can't see a whole lot...trying catch him to put in QT

Use a flash to take pic. May get clearer image. If truly looks cottony and whitish lump, I would guess a fungus or lypho.

Still hard to tell, but better. I would definitely get into qt. Then I would consider treating with a fungal/antibiotic. I would use Marine Aid from Fish Vet or Formalin (Many do not want to touch the stuff. I get that too.)

It now seems to have burst with skin dangling

 

[DeniseAndy]

Oh goodness. Is it a visual parasite? Is there any redness anywhere? How is the breathing?

 

[Hammer100]

 

[Hammer100]

Breathing pretty normal but definitely favoring that side

Breathing pretty normal but definitely favoring that side

Has the lump changed color to red or still white? Does it look as though the skin is peeling or sloughing off?

 

[Hammer100]

It doesn't look red....looks like it sloughed off
Doesn't seem to want to move the fins on that side of his body
