Fungus or Bacterial Infection on Tang?

[Khazmodain]

One of my yellow tangs has had a cotton-like white patch on its fin for about two days and it is now starting to spread to the body where the spot on the fin comes in contact. Tank had been fishless for 11 weeks, tang was prophylactically treated with CP and PraziPro while in a 6 week quarantine. He was doing some sparring with another yellow tang so I'm wondering if there was a wound that has become infected. It's really hard to get a good pic, but I've attached what I managed to capture.

There's pretty much no way I am going to catch the fish to treat in QT (tank is 400g and 36" tall with a lot of large rock). Is there anything somewhat reef safe to treat fungul or bacterial infections? I suspect most bacterial treatments would destroy the bacterial population. Kanaplex sounds like it may be the route I'd try, but I'd like to hear from someone with more fish disease experience than myself before I proceed.

Thanks!

api melafix and pimafix are reef safe, use them together to treat
potential bacterial and fungial infections.

Very hard to tell from the pics but it might be Lymphocystis. Keep the water quality in check and feed well and it should clear up on its own (if thats what it is).

I'll give it a try, thanks!

This would be my guess also. Along with making sure your water quality is good, soak your food in some Selcon.

Anything else that would cause Lymphocystis to pop up? I regularly soak food in Selcon. NO3 is 0.00 (using Red Sea Pro or Salifert) and PO4 varies between 0.00-0.02 (Hanna).

from what I know its a viral infection and a couple of water changes and good water quality usually seems to takes care of it.

My new melanurus wrasse had the same thing. I had him in QT and he developed the white cotton like patch on his side fin after a week. I suspected it might be water quality so I dosed for 14 days in paraguard while doing water changes, and at first it seem to help but the white patch remained. I tried kanaplex for 4 days after that but it didnt seem to do anything either. I have a clownfish in the QT with him and it didnt affect the clown. I figure it was probably lymph and being in the DT was going to be better for water quality than the 10 gallon tank... We'll see!

So I just put him in the DT yesterday.

there really isn't a cure for lymph just give them good food and pristine water and they usually heal on its own.

Good luck! Mine was pretty much the opposite scenario. Tang seemed perfectly fine in a 55g QT tank which had around 10 ppm NO3. Had no signs of any health concerns until it was moved into my 400g display with 0 NO3. About 3 days after moving into the DT is when the patch showed up. Water quality in my DT is definitely superior to what was in the QT which is why I've been hesitant to suspect lympho.
