While I was debating whether or not to move him to the permanent tank with the light, he appears to have calmed down, at least for now.

After a few more bouts with the top of the enclosure, he's been sitting on the side of the pond (gargoyle style, like he often does.)

I really am hoping that just for whatever reason this frog felt frisky this evening. It was as soon as we put the nightbulb on, which is when he typically comes out. Plan to continue standing here watching him until he either settles in or morning comes and I can call the vet.

Thanks again. I'm still hunting for anything I can find about someone experiencing something like this, and after about 4 hours now, still nothing really.
