Well if it is a fungal infection ketoconazole should clear it up.

It doesn't look like a fungal infection to me though. I looked through my Noga fish disease book and couldn't find anything that really fit exactly. If I had to guess I would say some type of myxozoan infection, which is not treatable. That would fit well with what the marine biologist guy said. Here's a google.books link to Noga's description of myxozoan infections...

i dont have the foggyiest. bump- good luck
 
My pleco did something similar and it was also getting worse before I moved him on to the LFS in surrender. Next time it shows up, see if you can get a scraping into a pipette or test tube and centrifuge it if you can. Get it down to a vet and throw him a few bucks or make an appointment and freeze the sample. He might take one look and be able to tell you right away what class of microorganism, if any, are in the sample.

If the fish is calm enough you could possibly lift him gently and do a vertical razor scrape above water for a more concentrated sample.
 
Best to identify the culprit before blindly trying random stressful treatments. But a salt bath isn't a bad start.

The way this thing cycles, there's always the chance you can break the circle at some point. It's just a matter if figuring out what it is we are fighting and how its life cycle works.
 
The whole tank had salt (3 tblspns/5 gallons) and 87 degrees for a week in May. The SDs, which were new, looked a little "sparkly" and I suspected ich. (My bad: ich would have been on their fins as well as their bodies.) The O developed spots during the treatment and the SDs remained as sparkly as ever. I bailed instead of waiting another week.
 
Good choice to end that attempt.

What jcon was suggesting is nothing like what you were doing. A hypersaline bath is an intense but short-lived dip into what may as well be brine. I don't remember the exact dosage, but it's crazy. The idea is that is ruptures most organisms on the surface of the fish. It's a little scary to see your fish float sideways, but it usually only lasts one or two minutes and deaths are rare. Not something I would try before getting an ID on a scraping.
 
wetmedia recommends Nitrofurazone for a bacterial infection . Is Furan 2 more likely to be effective than Jungle Labs Medicated Fish Foods? I'm assuming the food won't nuke my bio-filter.

Then again, I may decide to have a vet take a sample. I found a local one who sees fish.
