Help to identify this issue.

I discovered this on my clown in the 60 DT today.

What is it. We lost several fish in the 120 and now this.

I really need help here.

Any new fish added lately? Is the clown new? If so, it could be Brooklynella (read here). Bacterial infection is also a possibility.

it doesnt looke like Brook to me, but that is not to say it is not. it looks more like a sting or bacterial infection.

pull it. QT.

Clown is 10 months old in the tank. Nothing new in 3 months in that tank.
Had ich in 120 which wiped out the entire tank. My hope is this isn't ich. I am warming up the hospital tank and have it at hypo 1.009. Going to hit it with Focus and Kanaplex.

This isn't even close to resembling ich and I don't think its brook. This doesn't look like anything that just suddenly appeared, or did it? I've seen lympho grow in a mass like this, but that's unusual. If you don't get a good answer, I'd remove as much of the mass as you can with a tweezers and scalpel or razor blade and dab with mercurochrome. A wild guess would be some type of tumor.

I think a tumor may be very possible. Like you said, Lympho doesn't usually grow in a mass like that. And I doubt it's Brook if the clown has been in the tank for 10 months and no new additions for 3 months.

To the OP: If you decide to remove it with tweezers/scalpel, QT and treat with something like erythromycin. The probability of infection after "fish surgery" is high.

I stopped by the LFS (we have a great one here). They suggested using Melafix for starters.
Yes i showed them my picture, they agreed it wasn't Brook or Ich.
Ill try it for a couple days

I agree that ca is a real possibility. I have seen vibrio ulcers with a white base. It is hard to tell from the photo if it is an ulcer or sticks out. Anyway, your best bet is treating for a bacteria infection since pathology, surgery and chemo are out. Enrofloxacin or nitrofurazone or sulfa is where I would start. It doesn't look promising though.

Melafix doesn't do anything except make your tank smell like tea. Worthless IME.

Yeah, I have never heard anything positive about the stuff; except quotes from stores.
