Last night I went to check on my Red Eyed Tree Frog, and found him sleeping on a leaf. This concerned me a bit because of the fact that he normally wakes up within an hour of his light shutting off in his enclosure, and several hours had past since the light had gone off. I checked on him every few hours, and he hadn't budged an inch. This morning when I woke up, he was still in the same spot, sleeping. When the light shut off today, he woke up very slowly, keeping his left eye closed. He began to repeatedly open and shut his left eye, for no apparent reason. While he was doing this, I noticed that his right eye was extremely dilated while his other was not. He seems to be fine now, hunting some crickets that I let loose in his tank for him, but I was wondering if this day-and-a-half sleeping period, as well as his strange eye behavior, are things that I should be worried about. I would greatly appreciate any input!
