Jumping temps, lamps screwing up my humidity...... damn glass aquariums!!

I'm thinking about making the switch. I'm making a rack ANYWAYS cause I'm getting some new babies, and I think I'm going to put my 5 year old pair in some plastic. (YES, seperately!!! )

I wonder if they'll miss the space they had? My female is in a 55 gal., and i think the one my male is in is a 40 turned on it's side. If you all remember, I just seperated them about 2 months ago. Would it be too much stress to switch their caging... again????
I can try and tell them that they'll be warmer, but im not sure they'll listen...
