Question, Whites Tree Frog Behavior

[maxQ]

My question is will their habits change and should we worry? I've had my Whites for a while now and I think I know their behavior pretty good as you all know your Frogs habits. My whites are very active and humorous to watch at night, Leon loves to run around on the front glass like a wild man. Like most WTF they sleep most of the day and mine sleep up in the foliage that I have made for them, I think they are pretty happy. They were all bought at the same time, and I am guessing that all three of them are around 12-13 months old. Leon, my slightly larger guy always sits in the same spot during the day and kind of just watches everything and everybody from up above, I call him The Crypt Keeper. Last night Leon was up to his usual shenanigans but I noticed he was kinda hanging on the floor of the enclosure more than usual, I did put a few large fresh Magnolia Leaves in the bottom for them to play with and he was sitting on one of the larger leaves, this morning I woke up and this afternoon, he was still hanging around on the bottom, this is rare behavior for him, I reached in to pet him and he just moved to his large water dish, they have two, a shallow one and a deeper one. He seems happy just a little unusual for him is all. Can this be due to East Coast Climate change? Their water is changes daily, their diet is only crickets as they will not eat anything else, they eat every other day and their food gets dusted once a week with Calcium/D3. The Temp is currently 81, Humidity is currently 55%. I mist them daily as needed. As I was taking this picture he jumped 3 inches to grab a cricket on a leaf, and he got a great grab just like Ozzie Smith did for the St Louis Cardinals years ago. But he came right back to his water dish calling like he always does when The Price is right is on, LOL Again, he seems happy, just odd for him to be out this time of day. Any thoughts folks?
