Hello! I've had my White's Tree Frog, Mordin, for just over a month now. He seems perfectly healthy, he eats and poops regularly, climbs around, sleeps, and croaks. But recently I've noticed two things. One, he has some sort of discoloration on his nose. I tried taking a picture, but the camera won't pick it up. It's just a small spot on his left nostril that is slightly blue/purple/white-ish compared to the rest of him. I think it might be a bruise? I feed him in a bowl and sometimes when he dives for crickets, he hits the bottom fairly hard. Any ideas if I should be worried about this?
Also, when I first got him, he was bright green quite often.

but now, he's more brown most of the time, especially on the top of his head.

Yesterday I did his first ever tank cleaning. (replaced the substrate, took everything out and washed it down with water, scrubbed the sides of the tank) As soon as I took him out of the tank, He turned bright green, and when I put him back into the cleaned tank, he stayed green for the rest of the evening ( he seemed very happy to explore his newly rearranged home) But today, he's back to being brown. Am I doing something wrong? I generally keep the temperature around 80 degrees fahrenheit, and the humidity fluctuates. I try to keep it around 60%, never let it get lower than 50%, but sometimes right after I mist the tank it will get as high as 90% and then slowly go down.
