Black Mold and Other Problems

[FrogLoverSince5]

Hello, I have had a White's Dumpy Tree Frog (Named Shahar) Since February, and I have been having a few issues with her tank. One of the biggest issues I worry about is the mold. I notice it on her driftwood climbing set. It used to sit directly on the substrate and get mold all the time. Since then I have replaced the substrate with paper towels and have elevated the climbing set so it isn't constantly sitting on the wet ground. For a while the problem seemed under control but recently I have been seeing more and more mold. Most of it is white mold, but I have been seeing what I think is black mold. Usually when I seen this I take my whittling knife to it. (Don't worry, Shahar isn't on it when I do.) Should I take out the climbing set and let it dry or replace it? I mist the tank 2-3 times a day, though sometimes I have my automatic mister go off every 3 hours for 45 seconds to keep the humidity between 40 and 60 percent. The temperature is around 80 degrees.

Another thing I have noticed is that Shahar isn't very active. Most of the time she will sit in one spot until I take her out to feed. She is fed 1-2 crickets every 2 days. When feeding, she can be very active, constantly hopping about and out of the bucket, but as soon as I put her back in the tank she'll get on one of her climbing sets and sit there until the next feeding. Rarely will I find her moved elsewhere. Is this normal? She appears healthy. She has bright eyes, no marks on the skin (beside some scars that where there when I got her) and leaves a 'gift about once a week. Any thoughts?

Daytime temperature around 80 and a nighttime temp around 76 is good. The humidity is very low, it should be at least 60-80%. As far as the mold goes I don't know. I thought I read somewhere on this forum that white mold is okay but I could be wrong.

Also, how old is Shahar and how big are the crickets you are feeding her? 1-2 crickets every 2 days doesn't sound like enough.

Whites spend a lot of time just sitting and staring. My White's was very active when she had a tank mate and would constantly jump around the tank and want to know what the other one was doing. Now that her tank mate died, she spends most of her time just sitting in one spot, except it's feeding time.

Honestly, I not 100% sure how old she is, because the Pet store didn't keep track of that. I'm guessing that she's less than a year old, Maybe? I do know that she is pretty much full grown. I've had her for about 6 months now. The cricket's that I feed her are the large ones, about half an inch. They're a bit bigger than the space between her eyes. When I fed her she becomes very active and will hop all over the place, usually ignoring the second cricket. I know the humidity is kind of low but no matter what I do it won't go above 60% I've tried putting moss in but it became super saturated all the time and became super gross. I have two water dishes in the tank incase she ever feels like she needs to get wet. I also know that they can spend a lot of time sitting, but when she sits in one spot for two days without appearing as if she moved at all, I can't help but feel a bit worried.
