Bad mold problem, please help!

[classabear]

I have a baby Southern Brown Tree frog at the moment and it's my first frog. I've had him for about a month.. anyway.
When I first got him I was using Kritter Krumble ( I se it for my gecko, and it was natural so thought it'd be good) at that point I was misting pretty often to keep the humidity up.
After a week I noticed mold and a bad smell coming from the enclosure, so I changed out the substrate yesterday. I bought turtle rocks (big enough to not be accidentally ingested) and put a thin layer of water on the bottom to keep the humidity up. It worked, but this morning I found a white spider web like mold on the fresh branch that I put in the day before. I've since taken the branch out and disposed of it, but what am I doing wrong? I dont want to use barks since he gets it stuck all over him when he comes out of his water bowl.

Can anyone recommend me a new way to keep the humidity up without getting this mold? I dont want to harm my little froggy sorry for my noobness.

Paper towels are often used,I have them on the floor of my leopard gecko tanks. They are alot less trouble to clean up and the animals cant ingest them easily and get into trouble.

As they are from Southern Australia, I wouldn't think the humidity would need high. I am told they enjoy a mild temperatures.

I would suggest to put your frog in a "quarantine" tank and leave your tank to settle. There will always be mold problems in a new terrarium. If you see that mold does not disappear I will to invest in springtails or isopods. And let only a few running in the viv as they will reproduce.

Can I know what type of wood are you using? I suggest using cork, driftwood, mopani etc.

White mold on new wood added to a terrarium is very common. It will usually resolve itself between 4 days and 2 weeks. Adding Springtails to the tank will help keep the tank clean in general, they will eat frog poop, dead feeders and decaying plants. Oh and they will also eat mold

Isopods eat mold, springtails won't.

Bill - This is the first time I have heard that Springs don't eat mold. I feed my springs yeast which mold in a few hours and they love it... I have also seen them in the tanks swarming on wood that has developed some mold.

Oh, they will feed on mold, but normally only is there is moisture involved. If there is mold high in the tank where there is less moisture, they normally won't venture up there. But that is only been my observations. I am sure a lot depends on tank conditions. I think it also depends on the type of springtails as well. I only keep temperate springs, and they prefer to stay closer to the substrate.
