My local pet store got a nile in a month or so back, he's small maybe 8ish inches total. The weird thing is he is a complete sweetheart. He climbs on your shoulder and willingly hangs out, will sit on your hand without an issue and has no problems with being removed from his enclosure, never whipping, running or anything. He is really beautiful too and shows no sign of disease or anything that would make him slow in the head. Is it normal for baby Niles to be that content, do they grow up mean?
