Mae sure you disinfect the drift wood! That could be really dangerous for him! He is a cutie though, nice find, very nice.

Also, I didn't have time to read all of your posts I'm sorry, but if you do not have a temp gage or a humid gage, and have a glass tank, you should put that black plastic on the back of your tank to keep the heat in. I have the red bulb too, that is more for basking than regular light, but it will do just fine to keep him warm for now. Most likely you should keep it all the way up to keep it around 90 on one side. Also, try putting a damp towel ontop of your tank to keep the humidity up. Make a square out of it and put it smack dab in the middle of the top. It shouldn't cover the whole thing, but a small portion. This may help keep everything semi-stable until you have the equipment to properly tell.

Good luck!
