Sorry you had to learn this lesson the hard way Michael

! That is the reason you quarantine frogs, fish, anything that goes into an established set-up. Here is a Care Sheet for them in case it helps for future frogs:
http://www.frogforum.net/care-sheet-...warf-frog.html. Also, here is a bit more information on quarantine process:

If surviving frog is still alive; recommend check the linked care sheet and ensure all it's requirements are met. Do you have any pics of frog with fuzzy growth? Did fish showed any symptoms before dying? Hope rest of tank habitants survive
