I dropped some springtails in the bottom of my tank to help with it. It is unsightly but i was under the impression that it wont hurt the frogs.
The white kind that grows on the driftwood usually doesn't cause much of a problem and I've never had it harm my frogs, but with any fungal and mold growth you want to watch it carefully so it doesn't get out of control. Its a natural process for the wood to grow some mold as it is dead and therefore decaying. I always remove any mold I see due to amphibians being highly susceptible to fungal infections. The white mold grows rapidly showing back up within an hour of being wiped off or rinsed away from the wood, but usually doesn't pose much of a problem.

Always practice safety though and remove it whenever you see fungal or mold growth. Some Vivs have been known to grow mushrooms which is also a natural process and a sign of a fully functional Vivarium. I've had Mushrooms grow in my Viv before and since there are no animals in my Viv I just let them be.
