The problem I've got recommending brand name meds is that I'm in the UK - and your the other side of the pond. I don't know what meds you have to choose from.
If I had that in my tank, I'd use a med call Hexamita - by eSHa. The stuff treats for internal and external parasites, body fungus, hole-in-the-head, velvet, and a few bacterial things too. It's not expensive, and works pretty quickly, and if you're not sure what's wrong with a fish it's a bit of a cure-all.
If the Hexamita didn't work within a week, I'd do a 50% water change to dillute that med, and treat with a hard dose of another anti-bacterial med - just looked in my med box - and my purely anti-bac med is made by a company called "King British" - so not much help there - but I've heard good things about Jungle Labs stuff, which is more common over your way.
Go for the Hexamita if you can get hold of it - strong stuff - and usefull to have on hand for the future - especially for new arrivals
