I'm just talking out loud here, maybe the geckos' personalities really have nothing to do with whether they are Giants or not. My most docile gecko, King, is so nice and calm......... he's not even a giant......... but he does weigh over 110 grams in the off season
King will sit on my shoulder while I do homework, or if I'm working around the house. Maybe he's so docile because give him so much attention.
