I just got a fogging machine for my Chinese water dragon a few weeks ago, and the branches that are under it are starting to mold. The first branch that did it, I took out and soaked it in bleach and water, then let it dry out for a few days, and now there's another branch doing it. Does anyone know how to prevent it from molding?

Moulds love warm damp conditions... although based on some places I've lived before, you can ignore the warm part and just say they love damp!

Did you not have any issues with mould previous to getting the fogger? You could try cleaning your plants and the fogger itself and seeing if that solves it?

We've not had problems with moulds in high humidity vivs like CWDs, even with live plants.

I never had any problems until a few days ago. I cleaned the fogger and plants about three hours ago, haven't seen any more, yet! I'm going to clean the whole viv just in case there's any hiding mold spots.
