Howdy Mike,
I puzzled over what to say when I read your post. The first photo didn't seem to me to be female Nosy Be' colors but I really haven't paid that much attention to the early colorations of that locale as much as I should, especially since I have a male that I raised from 3 months to 2+ years old
. He never showed colors like either of yours but that shouldn't mean much coming from me... You could have convinced me that the 2nd photo was the female... How about a photo of the tail base of each to see which one is packing hemipenes? Your concern about health is valid. Sometimes it's the small signs that let us humans spot big problems early.
Photos of your setup and data to describe your "proper heating lighting, feeding and so on" will help get the conversation started with the rest of the group. Usually something will trigger some better ideas than what I've presented. Don't forget brand names of everything regarding lighting and supplements along with dosages, times etc...
