I inherited my gray tree frog from someone that isn't all that intelligent!! No realy, I mean litteraly!! She found him outside on top of the dumpster by the back of the store in a frozen state. Thinking it was dead she brought him into the store and put it in the trash. Well what do you know.. About 1 hour later another of the employees saw something moving around in the trash and picked it out. She had come back to life. They put it into a bucket and called me to come get her. Not knowing anything about these guy's I decieded to call and talk to my DNR guy. Because of how these guy's go into hibernation, he didn't feel that it would be good for the frog to be put back into it so soon. When they hibernate they seek coverage under logs, rocks, and even leaves. They produce the glucose that protects their organs and then any other liquid left in their bodies literaly freezes solid. They stay in this state until they leave hibernation. So I guess my question here is how is it that this guy is considered in hibernation at all.?? I beleive also that it is the temps that are affecting it. I have a 75 watt bulb on mine and she lay's right under it on the top leaf closest to it during the most of the day. Everyonce in awhile I will see her down on the log. To me this is her thermoregulating.. She is eating real well and has no problem hunting down those mangy little crickets. So again I agree, you need to change out those lights or as suggested get them raised up if you can't offer a lighter bulb..
