are lighter colors signs of stress or are darker one are. i ask because i just moved my cage from the bathroom (were he was by his self) to the living room. since being in the living room (were there are kids running around ) i dont know if he minds us being around cause all he does is sets there and bask he only seems to run away when i try to see if he is o.k. He is still eating;and if he is not basking he is a bright green so i dont know if he is happy or not
