awsome, I have friends with Niles and its usually hit or miss on them as far as temperament. Even docile by their standards is only handle when they let you. Infact their kinda bipolar as far as monitor species go. example I have a buddy that has full grown male adult that actually crawls up his leg to be picked up constantly but when his having one of those days dont even try getting near him. Once you understand that large monitors demand respect and work with you on their own free will when they learn to tolerate your company then it becomes a great relationship. Your nile looks in great shape and condition, try not to overfeed him please, chubby monitors are slow and unhealthy, even if he seems like he could keep eating. No matter how cute he looks at you, dont do it, keep him fed in moderation.
