Whites tree frog nose rubbing

Hi,
I haven't been on the FF for a long time, and just peeked in to see what was on with treefrogs...
Nothing really stands out to me as a huge caution. Good your going to cover the sides of the tank, this will help them to feel more secure.
Their color is very dark, the only time I've seen this dark color in my white's, was when he was sick (although he is typically a brownish shade). Are your white's usually such a deep, dark brown?
Have you checked for parasites or protozoa infection? They can tolerate infections for some time, but then one day it can become a real problem and they'll exhibit strange behavior and color.
Your temps could go a little higher during the day (about 82 F) and slightly higher at night (about 75 F), this may help.
Anything else you can think of? Chemicals in house, new pets or children making new and unfamiliar noises? A/C that may be vvented above tank? Anything at all?

That particular frog has been that color since the day we got them (several years ago.) The other one is a very light green. Day temps are good, about 77-82 during day, 70-75 at night. No new pets near them, no chemicals, etc. conditions have been the same for months now, and all of the sudden they started doing this. I have had a mushroom problem that started just two days ago, but they've been acting like this longer.
This just sprouted today. Could the mushrooms be a cause of anything?

I don't know about mushrooms? As far as I understand, they are fine.
Something has had to change for this new behavior. Perhaps crickets from a new vendor? New dusting powder? Different water conditioner?
You said in post #4 "4- temp is slightly above room temp during the day, room temp during night." In my world, slightly above room temp is like 75 F, I'm sorry I mis-understood.
Still, 70 at night is too far a drop from 82, drop should not be so significant. use a UTh on side wall of tank (maybe) at night to just bump the heat up slightly.
You don't want a 12 degree shift in temps, ever. This is very stressful. So difference between day and night temps should be about 7 degrees.
Can I see pics of your other white's?

***Also, you didn't answer in regard to testing for parasites or protozoa...
