I just noticed yesterday that my new JD has some white spots on his tail and on the outside of one set of gills. My first thought was ich, so I started treating with raised temps and salt, plus some melafix in case there were wounds. However, looking at the spots some of them appear larger and fuzzier than I would expect with ich. I'm a bit concerned now that it's a fungus rather than ich.
If it's columnaris or a body fungus, I've got Fungus Clear, Maracyn and I think Maracyn 2 but I know some meds can't be used with salt. Complicating this is the fact that I'm using the penguin biowheels for filtration and can't take carbon out. If it IS columnaris, I want to hit it as fast as possible before it spreads, and I know higher temps make it worse.
So far all fish still act normal and water params are fine. I'm doing another big water change today (>50%) to clear as much crap as possible out of the tank, and will keep doing daily smaller changes until this goes away.
Advice? Should I keep doing the salt and just drop the temps?
