URGENT Slimey patches on Frog!

[ZephAmp]

I've been keeping clawed frogs for 3 years and this is only my second time encountering diseases; I had a bout of red-leg when I first started that healed over just fine, but now I think this may be more serious.
A week ago two of my 3-4" females began regurgitating their meals.I thought this was because of stress right after eating; however, they both began spitting up with no disruptions. This morning I woke up and found the pigmented female with white patches all over her body and shed skin in her tank; I couldn't tell on the other female because she's albino, but there was also a lot of shed skin. One of my smaller females also regurged last night.
I have all three isolated in another room (they were in separate enclosures before; this is just an extra precaution.)
I fear this may be chytrid. 2 weeks ago I bought some fathead minnows from Cabelas, quarantined them for a week, and fed them to the frogs. I believe this is the source of the disease.
Right now, as I said, they're all isolated, and I've dosed their tanks with Sulfamethazine and Trimethoprim. Somebody I know recommended Tetracycline; is this worth a shot?
What other medications should I use? Is this chytrid?
**ALSO!
All the frogs are showing no interest in food right now. They're all still active and are in no way lethargic.

maybe you could throw oone of these people a e-mail???

I think there are lots of pathogens that could cause these symptoms, not just chytrid. In fact, I think Xenopus are relatively resistant to chytrid, so that seems unlikely.

Does this case sound similar?
Confusing X. laevis disease

Unless you know the cause (which could be bacterial, viral, fungal), any medication is going to be a shot in the dark.

Began treatment with the listed medications and the visible symptoms have disappeared. Still no lethargy (or appetite, though) but the frogs are looking better.

All 3 frogs are showing interest in food and visible symptoms/ excessive sloughing have disappeared/stopped. I'm going to continue treatment and keep the frogs fasting for 2 more days.
