It's effecting all amphibians, you're smart to get 2 at the same time, otherwise, you'd be looking at quarantining a new one for two months. That's what I'm doing with my ADF's.
In my sticky about the fungus, there's an attachment for treatment using Lamisil that's shown great promise in getting rid of the virus in ADF's.
I had been advised it's safe to give the treatment even if ADF's aren't showing symptoms as a precautionary measure.
I don't know if it would be the same dosage for Waxy Monkey Frogs.

Steve Busch and his herpetologist were the ones I originally contacted about the fungus. They were able to five me the proper dosage for ADF's.
Perhaps you can find some information there.
Good luck and post pics!
